PXM1E Platform Card in the new MGX 8850 (PXM1E) and MGX 8830 Switches
The new PXM1E-based switches include:
•
•
These switches are low end, cost effective multi-service switches based on the current MGX architecture with integrated uplinks on the processor card. The switch will provide a mix of broadband and narrowband services in addition to PNNI routing and signaling. It combines Narrow Band Service Module (NBSM) support, onboard network interface, and PNNI capability into a cost-effective single board switch. The PXM1E switches have these features:

•
•
•
•
•
•
•
•
•
•
•
•
The PXM1E has PNNI/ATM routing that supports the ATM Forum standard PNNI routing/signaling. It can be a peer to the PXM45 based switches in the single peer group and participate in the multi-peer groups. It supports different types of connections - SVC, SVP, S-PVC, and S-PVP. UNI 3.X/4.0 signaling and ILMI are used to setup SVCs. PXM1E will support 16K local switching connections.
This card is supported on the MGX 8850 (PXM1E) and the MGX 8830.
About the New MGX 8830 Switch
The Cisco MGX 8830 is an attractively priced 1.2 Gbps switch for sites with power and size constraints. It allows our customers to extend their geographic reach to more remote locations that need the high availability and features of the MGX 8850 in a smaller footprint.
The MGX 8830 supports interface modules for Frame Relay, ATM, Circuit Emulation, IP and Packet Voice.
New with the Cisco MGX 8830 is the industry's first ATM Modular optics, enabling service providers to mix and match single-mode, multi-mode and intermediate reach fiber on Broadband ports. Service providers can also add the broadband ports as needed, minimizing CAPEX.
About the New MGX 8850 (PXM1E) Switch
The Cisco MGX 8850 Multiservice Switch -- with the new PXM1E processor card -- is a low end, cost-effective multiservice switch based on the current MGX architecture with integrated network interfaces on the processor card. Like the MGX 8830, the switch will provide a mix of broadband and narrowband services in addition to PNNI routing. It scales from DS0 to OC-3/STM1.
ITU APS on AXSM/B and AXSM-E for PXM45
APS provides redundancy on SONET/SDH equipment to protect against line failure or fiber cut. APS permits the network to react to failed optical lines and/or optical interfaces by switching to an alternate line. This release supports the international standards ITU-T G.783 Annex A and B APS on AXSM/B and AXSM-E optical modules. APS 1+1 intercard redundancy requires use of an APS connector (MGX-APS-CON) to connect adjacent back cards.The complete list of architecture mode supported by software is:
•
•
•
•
•
ITU-T APS on AXSM/B is supported on the MGX 8850 (PXM45) and MGX 8950 switches. ITU-T APS on AXSM-E is supported on MGX 8850 (PXM45).Benefits
For a line failure, the detection and signaling of the failure occurs within 10 ms and the switchover occurs within 50 ms. For a card failure, the recovery will occur in less than 250msec. Using APS is a faster way to recover than can be achieved with Y-cable redundancy or ATM layer rerouting.
MGX-RPM-XF-512 Card
MGX-RPM-XF-512 is the next generation RPM card based on Cisco Patented Parallel Express forwarding (PXF) technology. Service Provider customers can use MGX-RPM-XF-512 to IP enable their FR/ATM infrastructure to provide high touch services like IP VPN's using MPLS with line rate QOS. The MGX-RPM-XF-512 GigE module can play a key role in service provider networks providing Metro Ethernet services in conjunction with Cisco ONS 15454.

The MGX-RPM-XF-512 card is supported on the MGX 8850 (PXM45) switch.
DSL Access Support — Single-ended SPVC Configuration
The feature enables configuration of both the endpoints of the SPVCs at the master end of the connection. With the feature, the connection needs be provisioned using the double ended provisioning model. The slave end of the connection is activated when the connection is established by the master end. This feature provides the ability to provision single-ended SPVC connections that originate on the DSLAM.
The Single-ended SPVC Configuration feature is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830, and MGX 8850 (PXM1E) switches.
Benefits
This feature enables improved interoperability with other vendor equipment and management stations.
250K Connections
The 250K Conns feature improves the scalability of the existing PXM45 node from the current 100K connections to 250K connections. This feature is supported only on the version B of the PXM 45 card with 256M of memory. On a single node, there can be a maximum of 250K SPVC/SPVP and SVC/SVP connections, where a maximum of 100k connections are persistent, and the other 150K connections are non-persistent. However, a node will support 250k persistent connections if it is not managed by CWM.
The number of persistent connections are limited by the number of connections supported by CWM, which is currently 100K.
The 250K Connections feature is supported on the MGX 8850 and MGX 8950 switches with PXM 45 version B cards.
Benefits
Customers can provision more connections on each switch.
Path and Connection Trace
The Path and Connection Trace feature allows the user to determine the path taken by a connection. The Path Trace feature is used for new connections in the process of being established. The Connection Trace feature is used to collect information on existing connections that have already been established. The Path and Connection Trace feature supported in the previous releases is based on the pre-standard version of the ATM Forum specification. In the current release the Path and Connection Trace feature will conform to ATM Forum standard PNNI Addendum for Path and Connection Trace, Version 1.0 af-cs-0141.000.
The Path and Conn Trace feature is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830 and MGX 8850 (PXM1E) switches.
Benefits
Standards based feature enables interoperability with other vendor equipment.
Network Clock Distribution Protocol (NCDP)
Network Clock Distribution Protocol (NCDP) is the means by which an accurate clock source is chosen by a node and is distributed to the rest of the nodes within a network for the purpose of ensuring synchronized network operation. NCDP based clocking provides resiliency of clock sources in a network which is vital for delay-sensitive traffic like video and voice traffic and allows the network to proactively switch clock sources rather than waiting for the quality of the active clock source to degrade.
NCDP is disabled by default. The only configuration required to enable the clock distribution is to enable it, then add the clock source references. NCDP can be turned off on a nodal basis or an interface basis. NCDP supports clock distribution to 200 nodes in the network. If the network is larger than 200 nodes, it should have multiple clocking domains with separate clock sources.
NCDP is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830, and MGX 8850 (PXM1E) switches.
Benefits
The implementation of NCDP based clock distribution on the MGX 8800 enables service providers to deploy large scale networks with integrated clocking suitable for delay sensitive data transfer.
Simple Network Time Protocol (SNTP)
Simple Network Time Protocol (SNTP) based time of day synchronization enables MGX 8800 nodes to have network time synchronization. Accurate time of day service is provided by synchronizing to Universal Time Coordinated (UTC) time. The standard based approach allows the switch to synchronize to any SNTP/NTP time server. This provides accurate time for statistics and alarms generated on the switch and enables accurate synchronization of such events between switches. The BPX uses a similar protocol for time distribution, but with the addition of SES, the BPX can also be synchronized using SNTP. In a network of BPX 86xx and MGX 88xx switches, time must be set on the BPX in order to be distributed consistently throughout the network.
SNTP is supported on the MGX 8850 PXM45, MGX 8950, MGX 8830 and MGX 8850 (PXM1E) switches.
Benefits
The SNTP Server functionality allows MGX 88xx and BPX 86xx switches to act as SNTP servers for the network.
Priority Routing
Priority based routing allows customers to specify the priority of connections. The priority allows high priority connections to be established before low priority connections. During failures, the high priority connections are also released before low priority connections. This action enables rerouting and reestablishment of high priority connections earlier than low priority connections.
This feature is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830, and MGX 8850 (PXM1E) switches.
Benefits
The customer can offer prioritized services based on connection priority.
Per Connection Overbooking
The Per Connection Overbooking feature for SPVCs provides improved control of network utilization for multiple tiers of service on a network supporting various trunk capacities. The percentage utilization factor is used for Connection Admission Control for the connection. The actual bandwidth used for Connection Admission Control for the connection is based on the PCR/SCR configured for the connection and the percentage utilization factor configured for the connection, combined with the percent utilization configured for interfaces in the selected path.
Overbooking means that less bandwidth is reserved for a connection, however it can use more bandwidth. The feature will enable overbooking to be performed on a connection basis.
Per Conn Overbooking is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830, and MGX 8850 (PXM1E) switches.
Benefits
This feature enables service providers to provide differentiated overbooking on a per connection basis rather than only on a uniform basis allowed by interface overbooking.
Preferred Routing
Preferred routing of connections provides the network operator a means of bypassing the PNNI route selection, and configuring a specific path through the network by which a connection will follow. Preferred routes can be configured as either Preferred or Directed routes. A Preferred route is a route which will follow the configured path if available, but will revert to a PNNI-selected route if the preferred route is not available. A Directed route is a route which will follow only the configured path; if the configured path is not available, the connection will remain unrouted.
In this first implementation of Preferred routes, a set of preferred routes is configured and assigned reference numbers, referred to as route sets. As connections are configured, they can be assigned to a particular route set. Each route set can currently contain one preferred (or directed) route.
Preferred routes can currently be specified only across a single PNNI peer group.
Since the preferred route is placed in the PNNI DTL by the source node, preferred routes are interoperable with any standard PNNI implementation.
Preferred routing is supported on the MGX 8850 (PXM45), MGX 8950, MGX 8830, and MGX 8850 (PXM1E) switches.
Benefits
The customer can control the selection of routes based on criteria other than those allowed in the route selection algorithms offered by PNNI.
Clear Service Module Configuration (clrsmcnf)
The clrsmcnf feature clears the configuration for a particular service module slot without affecting the configuration of other slots. This feature clears the configuration from both memory and disk (persistent). The clrsmcnf command will be a blocking command and the service module will be unavailable for provisioning during the entire duration of the command.
The clrsmcnf feature is supported on the following modules.
•
•
•
Benefits
The clrsmcnf feature does not impact or clear the configuration of the entire shelf (clrallcnf), it only clears the configuration for a particular slot thereby limiting the impact.
Disk Sync Verify
This feature provides a verification utility to check the synchronization of the disk "data" between the active PXM and standby PXM hard disks in the D:/DB2 directory. This disk synchronization verification utility provides a method of checking the "data" between the active PXM and standby PXM hard disks when invoked through CLI. This new CLI command, dskdbverify, invokes the task of verifying the "data" between the active PXM and standby PXM hard disks. This CLI command can be invoked both on the active PXM and standby PXM.
AXSM and AXSM-E Virtual UNI
A new port type called Virtual UNI (VUNI) is defined in addition to the already defined port types - UNI, NNI, VNNI (Virtual Trunk). This feature benefits both the MPLS and PNNI control plane.
Virtual UNI is supported on the MGX 8850 (PXM45) and MGX 8950 switches with the AXSM, AXSM/B, and the AXSM-E line cards.
Benefits
Customers can provision multiple Virtual ports each with a VP range on one physical line and thus allow transport of PNNI SPVPs. This feature removes the restrictions in previous releases with Virtual Trunks (VNNI) wherein only one VP could be defined so only SPVC could be transported across those VNNI interfaces. With Virtual Port an MGX, that is not configured with MPLS control plane (LSC) but is expected to transport PNNI and MPLS traffic to a neighboring switch configured with both MPLS and PNNI, can utilize this feature by defining a combination of VUNI (0-255 VP range) or VNNI (0-4095 range) or a VNNI (one VP only) on a single Physical ATM port thus allowing trunking as well as terminating traffic on a single physical port.
Virtual port allows the flexibility of defining separate Service Class Templates per logical Virtual port. This allows customers to engineer different behaviors of traffic on different logical ports on the same physical line.
Persistent Topology
The Persistent Topology feature enables CWM to maintain a persistent topology information of the entire network. One or more nodes will be designated as gateway nodes. Whenever CWM needs info about the network, it will query gateway nodes to collect necessary information. Gateway nodes are defined to be nodes from which CWM can query for information on the nodes contained within a peer group. A node needs to be configured to be a gateway node in every peer group through CLI or CWM before it can be used as one.
This feature will deliver the following functionality:
Cumulative collection of node info for topology database. Node info will contain nodeId, nodeName, lanIP, atmIP, sysObjId.
•
•
•
Benefits
This feature is useful to monitor the entire network as information of all the nodes irrespective of their state will be available to the CWM. It enables service providers who deploy large scale networks to keep track of the all the nodes in the network.SCT File Management and User-Configurable Names
This features implements version control for the SCT files such that the SCT files can have a major version, which would keep track of the parameters being added/deprecated, and a minor version to address limitations. A SCT management MIB was created to keep CWM and the switch in sync with respect to the MIBs. The SCT MIB contains a version parameter, and can be used to convey the minor and major versions of the SCT file. When the SCT file is modified by the user, the user can save the file as a new file or as a different version of the SCT file.
Detection of Non-native Controller Front Card and HDD Card
With this feature the runtime firmware detects when a controller front card or HDD card from another shelf/node is inserted into a node in the standby controller card slot. When the firmware detects a non-native PXM1E front (that has hard disk) or HDD back card is inserted into a node in the standby controller card slot, all the contents, except the contents in the C:FW, C:SCT, F:SCT and the image files and auto configuration files in the E:RPM, on the hard disk in the standby controller card slot will be deleted and the event log files will be backed up.
In other words, when a non-native hard disk is detected in the standby controller slot, the following files and directories will be preserved, event log files are backed up and everything else, including event log files, will be deleted on the non-native hard disk:
•
•
•
•
As a result of this feature, the hard disk on the standby controller slot no longer needs to be manually cleaned up when it is moved from another shelf/node.
VISM-PR Card
