Features and Enhancements in Release 5.0.20

This section contains the following new features and enhancements in Release 5.0.20:

Multilink Frame Relay on MPSM-T3E3-155

Port Oversubscription on MPSM-T3/E3-155

Channel Loopback on MPSM-T3E3-155

Enhancement to Statistics Counters on MPSM-T3E3-155

Multilink Frame Relay on MPSM-T3E3-155

Multilink Frame Relay (MFR) combines multiple individual links into one logical interface, called an MFR bundle. Multilink bundles help bridge the gap between DS1 and DS3 bandwidths, and can increase resiliency because the failure of a link usually does not bring down the whole bundle. In the MPSM-T3E3-155, each link is a T1 path on a channelized DS3 line or path.

The bundle interface serves as the Frame Relay data link, and performs the same functions as a physical Frame Relay interface. The bundle interface is visible to peers, so you configure Frame Relay functionality on the bundle interface. This section describes how to provision Mulitlink Frame Relay (MFR) services on the MPSM-T3E3-155 card.


Note Before you perform the procedures in this section, you must first configure the MPSM-T3E3-155 card and lines.


Features

The MPSM-T3E3-155 provides the following features:

MFR supported on the 3-port channelized T3 back card and the 2-port channelized OC-3 back cards.

Maximum of 42 bundles with up to 12 links per bundle.

Support for Class A, Class B, and Class C bandwidth classes.

Bundling of links that belong to different channelized T3 (up to 3 T3s) or STS-1s (up to 3 STS-1s).

Aggregation of only full T1/E1 links. MFR bundles with NxDS0 links are not supported.

12 bit sequence number format.

Two-byte Frame Relay header supported.

Support only for Extended Super Frame (ESF).

Both UNI and NNI mode as per FRF.16.1 are supported.

MPSM is transparent to end-to-end MFR and cannot be the initiating or terminating end for end-to-end MFR.

FRF.2.1 Annex 1 is supported on NNI-type bundle interfaces.

Restrictions

The MPSM-T3E3-155 has the following restrictions:

Aggregation of full T1 links only; MFR bundles with n x DS0 links are not supported

Blending T1 and E1 is not supported

Two-byte Frame Relay header (for example, 10 bit DLCI) is supported

Four-byte Frame Relay header for extended addressing is not supported. Frame Relay extended addressing uses a 23-bit DLCI field that enables support for thousands of DLCIs in NNI networks.

Frame Relay fragmentation is not supported.

Super Frame (SF) mode is not supported. Only ESF (Extended Super Frame) mode is supported for MFR services.

A maximum of 200 DLCIs per bundle is supported.

Multilink Frame Relay General Provisioning Procedures

This section contains procedures for provisioning MFR on the MPSM-T3E3-155. You create SPVCs for MFR the same way that you create Frame Relay SPVCs.


Note To support MFR, both ends of a physical link must be MFR capable, and the MFR configuration must match on both ends.


Creating an MFR Bundle

The MPSM-T3E3-155 implements MFR service using MFR bundles, which contain one or more serial links. When you add a bundle, the MPSM-T3E3-155 creates the corresponding Frame Relay data link layer interface for the service. After adding a bundle, you can then add MFR links to the bundle.

When you add a bundle using the addmfrbundle command, you specify the bundle number and activation class only; all other bundle parameters assume default values. You subsequently configure other bundle parameters using the cnfmfrbundle command. For example, after adding a Class C bundle you also need to configure the minimum number of links that must be operational before the bundle is operational.

To create an MFR bundle, perform the following steps:


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 Create an MFR bundle using the addmfrbundle command.

M8850_SF.10.MPSM155[FR].a > addmfrbundle <bundleNum> <activationClass>

Table 2 describes the parameters for the addmfrbundle command.

Table 2 addmfrbundle Command Parameters

bundleNum

Bundle Number, range 1-42

activationClass

Bundle activation class:

1=Class A—At least one bundle links must be operational for the MFR Bundle to be operational

2=Class B—All the bundle links must be operational for the MFR Bundle to be operational

3=Class C—Configured number of bundle links must be operational for the MFR Bundle to be operational.


This command creates a MFR bundle with the default configuration shown in Table 3.

Table 3 MFR Bundle Default Configuration 

Parameter
Description

minimumLinks

Specifies the minimum number of active links required for a Class-C MFR bundle to be operational. The default value is 1 link

helloTimer

Specifies the interval in seconds at which to send hello messages. The default is 10 seconds.

ackTimer

Specifies the maximum time period to wait for an acknowledgement message from the far end. The default is 4 seconds.

maxRetry

Specifies maximum number of times to re-try sending a hello message to the far end if an acknowledgement message is not returned. The default is 2 retries.

bundleName

Identifies the near-end bundle. The default bundle name is of the form node.slot.bundle, for example M8850_SF.Slot10.Bundle03


The following example creates MFR bundle 3 with Class A service type using default bundle parameters:

M8850_SF.10.MPSM155[FR].a > addmfrbundle 4 3

Step 3 To verify that the MFR bundle has been created, enter the dspmfrbundle <bundleNum> command, specifying the number of the bundle.

M8850_SF.10.MPSM155[FR].a > dspmfrbundle 4
    Bundle Number                   : 4

    Far End Bundle Name             : <not defined>


Configuring an MFR Bundle

When you add an MFR bundle, most of the configuration options are defaults (See Table 3). For example, if you want to add a bundle with a minimum number of links that is greater than one, you have to configure the minimum number of links is this procedure.

To configure an MFR bundle, perform the following steps:


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 If the MFR bundle is administratively up, bring it down by entering the dnmfrbundle <bundleNum> command.

Step 3 Configure MFR bundle parameters using the cnfmfrbundle command.

M8850_SF.9.MPSM155[FR].a > cnfmfrbundle -bundle <bundleNum>  
[-class <activationclass>] [-minlinks <minimumlinks>] 
[-hellotimer <hellotimer>] [-acktimer <acktime>] 
[-maxretry <maxretry>] [-bname <bundleName>]

Table 4 describes the parameters for the cnfmfrbundle command.

In the following example, the user increases the minimum number of links for a Class C MFR bundle to 4 and sets the maximum number of retries to 4.

M8850_SF.9.MPSM155[FR].a > dnmfrbundle 4 
M8850_SF.9.MPSM155[FR].a > cnfmfrbundle -bundle 4 -minlinks 4 -maxretry 4

Step 4 Restore the bundle to the administrative up state by entering the upmfrbundle <bundleNum> command.

Step 5 To verify MFR bundle configuration, enter the dspmfrbundle <bundleNum> command, specifying the number of the bundle you want to display.

M8850_SF.10.MPSM155[FR].a > dspmfrbundle 4
    Bundle Number                   : 4
    Activation Class                : C

    Far End Bundle Name             : <not defined>


Adding Links to an MFR Bundle

After you have established and configured an MFR bundle, you can add links to the bundle. Adding a link sends an Add-Link request message to the far-end of the bundle. A link is actively operating in a bundle only after the following conditions are met:

An Add-Link acknowledgement is received from the Far end for the transmitted Add-Link message.

An Add-Link request is received from the Far-end.

After both messages are received from the far-end, the MFR link is ready to transmit and receive data. Depending on the Activation Class of the bundle, the Bundle Up Indication is sent by the MFR Bundle layer to the Frame Relay Data Link layer under the following conditions.

Class A bundles—After receiving link activation confirmation for one link.

Class B bundles—After receiving link activation confirmation for all links in the bundle.

Class C bundles—After a predefined number of links in the bundle confirm activation.

To add a link to an MFR bundle, perform the following steps:


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 Bring up the links (paths) that you want to add to the MFR bundle by entering the uppath [-path_filter] <path_num> command. To display all available paths, enter the dsppaths -all command.

Step 3 Add links to the MFR bundle by entering the addmfrlnk command. The new link has a default name with the format node.card.link.

M8850_SF.10.MPSM155[FR].a > addmfrlnk <link> <bundleNum> 

Table 5 describes the parameters for the addmfrlnk command.

Table 5 addmfrlnk Command Parameters

Parameter
Description

link

Specifies a DS1 or E1 path:

DS3 payload: bay.line.sts:ds1

VT payload: bay.line.sts:vtg.vt

where: bay=1, line=1-3, sts=0-3, ds1=1-28,
tug3=1-3, vtg=1-7, vt=1-4 (VT15) or 1-3 (VT2)

Note Enter the dsppaths -all command to display all available paths on the card.

bundleNum

Bundle number, in the range 1-42

Note Enter the dspmfrbundles command to display all bundles on the card.


The following example adds link 1.1:11 (bay 1, DS3 1, DS1 11) to bundle 4.

M8850_SF.10.MPSM155[FR].a > addmfrlnk 1.1:11 4

Step 4 To verify that the link was added to the MFR bundle, enter the dspmfrlnk <linkNum> command, specifying the number of the bundle.

M8850_SF.10.MPSM155[FR].a > dspmfrlnk 1.1:11
  Link Number                      : 1.1:11

  Link Far End Name                : <not defined>
  Link Far End Bundle Name         : <not defined>
  Link PHY Operational Status      : Down


Configuring MFR Links

Optionally, reconfigure the near-end name of the MFR link. Links have a default near-end name in the format node.slot.link, for example M8850_SF.Slot10.Link11.

To rename a link, perform the following steps.


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 Reconfigure the link by entering the cnfmfrlnk command.

M8850_SF.10.MPSM155[FR].a > cnfmfrlnk -link <lnkNum> -lname <linkname> 

Table 6 describes the parameters for the cnfmfrlnk command.

Table 6 cnfmfrlnk Command Parameters

  Link Far End Bundle Name         : <not defined>
  Link PHY Operational Status      : Down


Adding a Port to the MFR Bundle

You need to add a port to an MFR bundle to connect it to other endpoints.

To add a port to an MFR bundle, perform the following steps:


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 Prepare to add a port to the MFR bundle:

a. Determine the bundle number on which you will add the port. To display a list of the MFR bundle numbers, enter the dspmfrbundles command.

b. Verify that the bundle and port number you want to use are not already configured. To display a list of the Frame Relay ports already configured on the MPSM-T3E3-155 card, enter the dspports command in the Frame Relay service context.

When you add a port, you must specify a port number that is unique on the MPSM-T3E3-155 card. For example, if port number (If Num) 5 is assigned, you cannot use port 5 on any other line or bundle on that MPSM-T3E3-155 card.

Step 3 Add and configure an MFR port for the MFR bundle by entering the addmfrport command:

M8850_SF.10.MPSM155[FR].a >addmfrport <ifNum> <bundle> <portType> <sct> 
[-rat <rat>] [-oversub <oversub>] 
[-lmiSig <lmiSigType> ] [-asynUpdt <updateType>] 
[-elmi <elmiState>][-segLmi <segLmiStatus>] 
[-t391 <t391Value>] [-t392 <t392Value>] 
[-n391 <n391Value>] [-n392 <n392Value>][-n393 <n393Value>] 

Table 7 lists the parameter descriptions for adding MFR ports.

Table 7 addmfrport Command Parameters 

ifNum

A number for the port, in the range 1-1003.

bundleNum

The MFR bundle number, in the range 1-42.

Note Enter the dspmfrbundles command to display all MFR bundles on the card.

portType

Type of logical interface (port):

1 = Frame Relay Service

3 = Frame Forward (Not applicable for MFR bundles)

sct

The Service class template (SCT) for the port, range 0-255.

Default: 0

Note The port SCT file must exist and be registered on the PXM disk before it is available for use. Enter the PXM dspscts command to view all registered SCT files on the PXM card.

-rat

The egress service ratio of the high priority and the low priority queues, range 0-15.

Enter 0 to indicate that no service ratio is configured. In this case, bandwidth is allocated to both the high priority and the low priority queues on demand, which means that traffic is dynamically allocated on a first-come, first-serve basis.

The default setting is 1. In this case, the traffic of the CBR and rt-VBR service categories is allocated to the high priority queue, while the traffic of the nrt-VBR, ABR, and UBR service categories is allocated to the low priority queue.

-oversub

Oversubscription control:

1 = enable

2 = disable (default)

-lmiSig

LMI signaling protocol type:

2 = No Signaling (default)

3 = StrataLMI

4 = AnnexAUNI

5= AnnexDUNI

6 = AnnexANNI

7 = AnnexDNNI

Note When LMI is configured, the maximum number of connections per port for Strata LMI port is 560 and for Annex A/D UNI/NNI port is 898.

-asynUpdt

Enables or disables asynchronous updates. Asynchronous updates are an extension to the LMI protocol that notify the user immediately of changes in PVC and Multicast status. Before enabling this feature, make sure that any DTE equipment you are connected to supports asynchronous updates from the network.

Asynchronous update control:

1 = Disable both Asynchronous Status Updates and Unsolicited Full Status (default)

2 = Enable Asynchronous Status Updates

3 = Enable Unsolicited Full Status

4 = Enable Asynchronous Status Updates and Unsolicited Full Status

-elmi

Enable or disable enhanced LMI. Enhanced LMI enables the automatic exchange of Frame Relay QoS parameter information between the DTE and DCE. When enabled on both the DTE and the MPSM port, this allows the DTE device to learn QoS parameters from the frame relay port and use them for traffic shaping, configuration, or management purposes.

1 = enable

2 = disable (default)

-segLmi

Segmented LMI control:

1 = enable

2 = disable (default)

-t391

T391 timer. This is the Link Integrity Verification polling timer. The user (DTE) sends Status Enquiry messages to the network (DCE) every T391 seconds. An error is recorded if a Status message is not received within T391 seconds. The T391 counter always applies to the user equipment. It applies to the user and network if NNI bi-directional polling is present. Range 5-30. Default: 10

-t392

T392 timer. This is the Polling Verification timer. The network (DCE) expects Status Enquiry messages from the user (DTE) every T392 seconds. If the network does not receive a Status Enquiry message from the user within T392 seconds and the timer expires, then the network records a missing Status Enquiry message by incrementing the N392 counter. This timer value must be set greater than the T391 timer. The T392 timer always applies to the network. It applies to the network and user if NNI bi-directional polling is present. Range 5-30. Default: 15

-n391

N391 counter. This setting establishes the Full Status (status of all PVCs) polling cycle. The user (DTE) sends a Full Report Status Enquiry to the network (DCE) every N391 polls. The N391 counter always applies to the user equipment. It applies to the user and network if NNI bi-directional polling is present. Range 1-255. Default: 6

-n392

N392 counter. This setting specifies the UNI/NNI error threshold. This is the number of errors during N393 events that will cause an error condition. This counter should be less than or equal to the N393 counter. This counter can apply to both the user (DTE) and the network (DCE). Range 1-10. Default: 3

-n393

N393 counter. This setting is the monitored UNI/NNI events count, which must be greater than the N392 counter. N392 errors during N393 events will cause an error condition. If the N393 counter is set to a value much less than the N391 counter, the port could go in and out of an error condition without notification to either the user equipment or the network. This counter can apply to both the user (DTE) and the network (DCE). The value of this parameter should be greater than that for the -n392 parameter. Range: 1-10. Default: 4


Step 4 To display a list of all Frame Relay ports configured on the MPSM-T3E3-155 card, enter the dspports command in the Frame Relay service context. Port numbers are listed in the ifNum (interface number) column. If you want to view information on a particular port, note the number of that port.

In the following example, the user adds MFR port 4 to bundle number 4 with service class template 0.

M8850_SF.10.MPSM155[FR].a > addmfrport 4 4 1 0

Step 5 To verify the port, enter the dspports command:

M8850_SF.10.MPSM155[FR].a > dspports

Deleting an MFR Bundle, Link, or Port

Use the following procedure to delete an MFR bundle, link, or port.


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 To delete an MFR port, enter the delport <ifNum> command. You must delete connections to the port before deleting the port.

Step 3 To delete an MFR link, enter the delmfrlnk <link> command. You must delete the port before deleting the last link.

Deleting a link sends a Remove-Link request message to the far-end of the link. The bundle stops transmitting data on the link after the Remove-Link request has been sent. However, data received on the link is processed until the acknowledgement for the Remove-Link request is received.

Step 4 To delete an MFR bundle, enter the delmfrbundle <bundleNum> command. You must delete all links from the bundle before deleting the bundle.

Step 5 To verify the deletion of ports, links, or bundles, enter the dspports, dspmfrlnks, or dspmfrbundles commands respectively.


Port Oversubscription on MPSM-T3/E3-155

This release adds Frame Relay port oversubscription to the MPSM-T3/E3-155 card. When enabled, the total committed information rate of all connections on the port can exceed the physical port rate. However, traffic is always limited to the physical port rate.

This feature affects the following commands:

addport—new -oversub option to enable or disable oversubscription for a new port

cnfport—new -oversub option to enable or disable oversubscription for an existing port

dspport— also displays activation and oversubscription status for a port

The following table describes the oversubscription option.

-oversub <value>

Oversubscription control. Enter a number to enable or disable the oversubscription indicator, as follows:

1 = enable

2 = disable


Channel Loopback on MPSM-T3E3-155

Channel loopback is a feature that loops all channel traffic (data and OAM) back to the source. There are two types of loopback:

Ingress—loops incoming line (CPE) traffic back to the line

Egress—loops outgoing (network) traffic back to the switch

You specify the type of loopback when you activate a channel loopback. You activate, deactivate, and display channel loopbacks using the commands shown in Table 8. Channel loopback configurations are persistent, so they survive a card reset.

Table 8 MPSM-T3E3-155 Channel Loop Commands 

Command
Description

addchanloop

Activates a channel loopback

delchanloop

Features and Enhancements in Previous Release 5.0.10

This section contains the following new features and enhancements in Release 5.0.10:

PXM45 RAS

Standard Available Bit Rate (ABR) Mapping Changes (PER 4148)

License Management

AXSM-16-155-XG Feeder Support

Unique Device Identifier (UDI)

CES Line Conditioning

Previously, on a CESM card with structured ports, the line is not conditioned when an OAM AIS is received on a VC. For unstructured ports, the line is conditioned (AIS is sent on the line). Non line conditioning is a problem for applications that convert T1 to E1. For this application, a structured port of 24 time slots is created on both ends. Therefore, when the T1 line goes into alarm, the far end E1 line stays up.

This feature enables CESM-8-T1E1 and MPSM-8-T1E1 cards in CES mode to send AIS on the line if OAM AIS is received on any channel irrespective of other channels on the line. When line conditioning (lineCondition) is enabled on a connection and OAM AIS is received on the connection from the network, AIS is generated on the line. AIS generation is irrespective of other active connections on the line. Similarly, when the VC stops receiving OAM AIS from the network, AIS generation on the line is stopped. This parameter is only applicable to connections on a structured port.

The following limitations apply to CES conditioning:

1. This channel parameter is not available for configuration upload.

2. Two ends of the CES channels have enabled the line condition, and two ends of the lines have physical loop back. After removing one loop back and inserting back, two ends of the lines are stuck in alarm. The channel is also stuck in alarm.

3. Two ends of the CES channels have enabled the line condition, and two ends of the lines are connected to CPE. Two CPEs that keep having alarms and alarm recovering might cause the line to be stuck in alarm. However, this occurrence is of a very low probability.

Workaround for limitations 2 and 3 is to add a soft loop back (addnloop) to one line, or, disable the line condition from one end of the channel.

Platforms

The feature is supported on the following MGX switches:

MGX 8850 (PXM45)
