Release Notes for SAN-OS Release 2.1(2)
New Features for SAN-OS Release 2.1(1a)
| Feature | Description |
| Inter-VSAN Routing (IVR) Network Address Translation (NAT) | Allows non-unique domain IDs in an IVR topology. This feature simplifies the deployment of IVR in an existing fabric. |
| IVR VSAN topology auto mode | Uses CFS configuration distribution in auto mode to learn the topology of the IVR-enabled switches in the network. |
| IVR service groups | Reduces the amount of traffic to non-IVR-enabled switches by restricting IVR-related traffic to the IVR-enabled switches. |
| Multiple autonomous fabric IDs (AFIDs) for IVR | Allows more that one VSAN in the network with the same VSAN ID. |
| IVR LUN zoning | Allows IVR to directly support LUN zoning. |
| IVZ QoS | Allows IVZ QoS to be configured separately from other zone attributes. |
| SANTap | Allows third-party data storage applications, such as long distance replication and continuous backup, to be integrated into the SAN. |
| Network-Accelerated Storage Backup (NSAB) | Supports server-free backups in the SAN. |
| Distributed configuration copy | Instructs the other switches in the fabric to save their configurations to their local NVRAM. |
| Enhanced IP compression auto mode | Allows auto mode option to use a combination of compression modes to effectively utilize the WAN bandwidth. |
| Zone, zone set, fcalias, and zone attribute set cloning | Allows cloning of a new zone, zone set, fcalias, or zone attribute set can be cloned from an existing zone, zone set, fcalias, or zone attribute set. |
| VSFN support on the SSM | Provides support for VSFN on the SSM. |
| File system support for log: | Allows the file system commands to support a new directory called log: for system message log files. |
| iSCSI cut-thru routing mode | Provides iSCSI cut-thru routing mode in addition to pass-thru and store-and-forward modes. |
| Disable interface bit error rate thresholds | Allows the user to disable bit error rate threshold for a Fibre Channel interface. |
Release Notes for SAN-OS Release 2.1(1a)
New Features for SAN-OS Release 2.0(2b)
| Feature | Description |
| Fibre Channel write acceleration | Provides support for Fibre Channel write acceleration on the ASM and SSM, which minimizes application latency or reduces transactions per second over long distances. |
| SCSI flow statistics | Collects statistics for SCSI flows. |
| FICON enhancements | Provides support for FICON on MPS-14/2 modules. |
| ELP enhancement | ELP is compliant with FC-SW-3. |
Release Notes for SAN-OS Release 2.0(2b)
New Features for SAN-OS Release 2.0(1b)
| Feature | Description |
| Extended ping command | Provides additional options to verify the connectivity of a remote host or server. |
| Initial setup changes | The questions in the initial set up routine and the order in which they appear is enhanced to reflect the various changes in the Cisco SAN-OS Release 2.0(1b) software |
| New inventory information | Displays information for the field replaceable units (FRUs) in the switch, including product IDs, serial numbers, and version IDs. |
| Cisco Fabric Services Infrastructure | Enables efficient database distribution and fosters device flexibility. |
| Dynamic VSANs | Allows you to dynamically assign VSAN membership to ports based on the device WWN. |
| Graceful shutdown | Allows the Cisco SAN-OS software to implicitly perform a graceful shutdown if you shut down an interface operating in the E port mode or if a Cisco SAN-OS software application executes a port shutdown as part of its function. |
| Extended BB_credits | Allows you to configure up to 3,500 receive BB_credits on a Fibre Channel port to facilitate BB_credits for long haul links. |
| Small form-factor pluggable (SFP) | Replaces the term FCOT (Fibre Channel optical transmitter) with the term SFP in the Cisco SAN-OS software and in the documentation. |
| PortChannel | Includes a new mode (ACTIVE) and a new protocol (autocreation). |
| Zone-based QoS | The zoning feature provides an additional segregation mechanism to configure the Quality of Service (QoS) priority as a zone attribute. |
| Enhanced zoning | Is enhanced to be compliant with FC-GS-4 and FC-SW-3. Both standards support basic zoning and enhanced zoning functionalities. |
| Distributed Device Alias Services | Allows you to distribute device alias names on a fabric-wide basis. |
| Security |
|
| Enable SNMP trap notification | Enables a specific SNMP trap (for example, fcdomain traps) notification. |
| RMON configuration | Allows you to configure RMON alarms and events through the CLI. |
| Multicast compliance | To interoperate with other vendor switches, the Cisco SAN-OS software uses the lowest domain switch as the root to compute the multicast tree in interop mode. |
| IP-ACL changes | As of Cisco SAN-OS Release 2.0(1b), you can also apply IP-ACLs to Gigabit Ethernet interfaces (IPS modules) and Ethernet PortChannel interfaces. |
| IP storage |
|
| AAA accounting log | The AAA accounting log size cannot be configured. The default size of the accounting log is increased to 250,000 bytes and cannot be changed. |
| IP Security (IPsec) | Provides security services at the IP layer, including protecting one or more data flows between a pair of hosts, between a pair of security gateways, or between a security gateway and a host. |
| Internet Key Exchange (IKE) | IPsec uses the IKE protocol to handle protocol and algorithm negotiation and to generate the encryption and authentication keys to be used by IPsec. |
| Call Home enhancements | Provides message throttling capabilities, periodic inventory messages, port syslog messages, and RMON alert messages. |
| Port tracking | Is unique to the Cisco MDS 9000 Family. It uses information about the operational state of the link to initiate a failure in the link that connects edge device. |
| SAN extension (SET) tuner | Is unique to the Cisco MDS 9000 Family. It helps you optimize FCIP performance by generating SCSI I/O commands and directing such traffic to a specific virtual target. |
| Command Scheduler | Helps you schedule configuration and maintenance jobs in any switch in the Cisco MDS 9000 Family. |
| WWW changes | Exchange Link Protocol (ELP) and Exchange Fabric Protocol (EFP) use WWNs during link initialization. |
| FC ID changes |
|
| Storing the last core to Flash | The last core dump (service core) is automatically saved to the Flash in the /mnt/pss/ partition before the switchover or reboot occurs. |
