Syntax Description

This command has no other arguments or keywords.

Defaults

Disabled.

Command Modes

Command History

This command was introduced in Cisco MDS SAN-OS Release 1.3(1).

Usage Guidelines

Enabling active equals saved ensures that you do not have to perform the copy running-config startup-config command to save the FICON configuration as well as the running configuration. If your switch or fabric consists of multiple FICON-enabled VSANs, and one of these VSANs has active equals saved enabled, changes made to the non-FICON configuration causes all FICON-enabled configurations to be saved to the IPL file.

Refer to the Cisco MDS 9000 Family Configuration Guide for further information.

Examples

The following example enables the automatic save feature for a VSAN.

switch(config)# ficon vsan 2

switch(config-ficon)# active equals saved 

The following example disables the automatic save feature for this VSAN.

switch(config-ficon)# no active equals saved

switch(config)#

Related Commands

Command	Description
show arp	Displays the ARP table.

attach module slot-number

Syntax Description

slot-number

Specifies slot number of the module to which to connect.

Command Modes

EXEC.

Command History

This command was introduced in Cisco MDS SAN-OS Release 1.0(2).

Usage Guidelines

You can use the attach module command to view the standby supervisor module information, but you cannot configure the standby supervisor module using this command.

You can also use the attach module command on the switching module portion of the Cisco MDS 9216 supervisor module, which resides in slot 1 of this two-slot switch.

To disconnect, use the exit command at the module-number# prompt, or type $. to forcibly abort the attach session.

Examples

The following example connects to the module in slot 2. Note that after you connect to the image on the module using the attach module command, the prompt changes to module-number#.

switch# attach module 1

Attaching to module 1 ...

To exit type 'exit', to abort type '$.' 

module-1# exit

autonomous-fabric-id (IVR topology database configuration)

To configure an autonomous fabric ID (AFID) into the Inter-VSAN Routing (IVR) topology database, use the autonomous-fabric-id command. To remove the fabric ID, use the no form of the command.

autonomous-fabric-id fabric-id switch-wwn swwn vsan-ranges vsan-id

no autonomous-fabric-id fabric-id switch-wwn swwn vsan-ranges vsan-id

Syntax Description

fabric-id	Specifies the fabric ID for the IVR topology. Note For Cisco MDS SAN-OS images prior to release 2.1(1a), the fabric-id value is limited to 1. For Releases 2.1(1a) and later images, the fabric-id range is 1 to 64.
switch-wwn swwn	Configures the switch WWN in dotted hex format.
vsan-ranges vsan-id	Configures up to five ranges of VSANs to be added to the database. The range is 1 to 4093.

Defaults

None.

Command Modes

IVR topology database configuration submode.

Command History

Release	Modification
1.3(1)	This command was introduced.
2.1(1a)	Modified range for fabric-id.

Usage Guidelines

The following rules apply to configuring AFIDs to VSANs:

•The default AFID of a VSAN is 1.

•Each VSAN belongs to one and only one AFID.

•A switch can be a member of multiple AFIDs.

•AFIDs at a switch must not share any VSAN identifier (for example, a VSAN at a switch can belong to only one AFID).

•A VSAN identifier can be reused in different AFIDs, without merging the VSANs, as long as those AFIDs do not share a switch.

You can have up to 64 VSANs (or 128 VSANs for Cisco MDS SAN-OS Release 2.1(1a) or later) in an IVR topology. Specify the IVR topology using the following information:

•The switch WWNs of the IVR-enabled switches.

•A minimum of two VSANs to which the IVR-enabled switch belongs.

•The autonomous fabric ID (AFID), which distinguishes two VSANs that are logically and physically separate, but have the same VSAN number. Cisco MDS SAN-OS Release 1.3(1) and later supports only one default AFID (AFID 1) and thus does not support non-unique VSAN IDs in the network. As of Cisco MDS SAN-OS Release 2.1(1a), you can specify up to 64 AFIDs.

---

Note Two VSANs with the same VSAN number but different fabric IDs are counted as two VSANs out o f the 128 total VSANs allowed in the fabric.

---

The following command enters the configuration mode, enables the IVR feature, enters the VSAN topology database, and configures the pWWN-VSAN association for VSANs 2 and 2000:

switch# config terminal

Enter configuration commands, one per line.  End with CNTL/Z.

switch(config)# ivr enable

switch(config)# ivr vsan-topology database

show autonomous-fabric-id database	Displays the contents of the AFID database.
show ivr	Displays IVR feature information.

autonomous-fabric-id (IVR service group configuration)

To configure an autonomous fabric ID (AFID) into an IVR service group, use the autonomous-fabric-id command in IVR service group configuration submode. To remove the autonomous fabric ID, use the no form of the command.

autonomous-fabric-id afid vsan-ranges vsan-id

no autonomous-fabric-id afid vsan-ranges vsan-id

Syntax Description

afid	Specifies the AFID to the local VSAN.
vsan-ranges vsan-id	Configures up to five ranges of VSANs to be added to the service group. The range is 1 to 4093.

Defaults

None.

Usage Guidelines

Before configuring an IVR service group, you must enable the following:

•IVR using the ivr enable command

•IVR distribution using the ivr distribute command

•Automatic IVR topology discovery using the ivr vsan-topology auto command

To change to IVR service group configuration submode, use the ivr service-group name command.

Examples

The following command enters the IVR service group configuration submode and configures AFID 10 to be in IVR service group serviceGroup1:

switch# config terminal

Enter configuration commands, one per line.  End with CNTL/Z.

switch(config)# ivr enable

switch(config)# ivr distribute

---

Note In user-configured VSAN topology mode, the AFIDs are specified in the IVR VSAN topology configuration itself and a separate AFID configuration is not needed.
