Command Modes

Configuration mode.

Command History

This command was modified in Cisco MDS SAN-OS Release 1.2(2).

Usage Guidelines

Change to the VSAN database submode to issue this command.

The interface range must be in ascending order and non-overlapping. You can specify a range using a hyphen and several interfaces using commas:

•The interface range format for a FC interface range is
fcslot/port - port , fcslot/port , fcslot/port
(For example, show int fc1/1 - 3 , fc1/5 , fc2/5)

•The interface range format for a FV interface range is
fvslot/dpp/fvport - fvport , fvslot/dpp/port , fvslot/dpp/port
(For example, show int fv2/1/1 - 3 , fv2/1/5 , fv2/2/5)

•The format for a PortChannel is
port-channel portchannel-number.subinterface-number
(For example, show int port-channel 5.1)

Examples

The following examples show how to create multiple fabrics sharing the same physical infrastructure and to assign which ports are in which VSAN.

switch# config terminal

switch(config)# vsan database

switch(config-db)#

switch-config-db# vsan 2

switch(config-vsan-db)# vsan 2 name TechDoc 

updated vsan 2

switch(config-vsan-db)# vsan 2 loadbalancing src-dst-id

vsan policy deny

To configure a vsan-based role, use the vsan policy deny command in configuration mode. Use the no form of this command to delete a configured role.

vsan policy deny
permit vsan vsan-id

vsan policy deny
no permit vsan vsan-id

no vsan policy deny

Syntax Description

permit	Remove commands from the role.
vsan vsan-id	Specifies the VSAN ID. The range is 1 to 4093.

Defaults

Permit.

Command Modes

Configuration mode—role name submode.

Command History

This command was introduced in Cisco MDS SAN-OS Release 1.2(1).

Usage Guidelines

You can configure a role so that it only allows commands to be performed for a selected set of VSANs. By default, the VSAN policy of a role is permit. In other words, the role can perform commands configured by the rule command in all VSANs. In order to selectively allow VSANs for a role, the VSAN policy needs to be set to deny and then the appropriate VSANs need to be permitted.

Examples

The following example places you in sangroup role submode.

switch# config t 

switch(config)# role name sangroup 

switch(config-role)# 

The following example changes the VSAN policy of this role to deny and places you in a submode where VSANs can be selectively permitted.

switch(config)# vsan policy deny 

switch(config-role-vsan) 

The following example deletes the configured VSAN role policy and reverts to the factory default (permit).

switch(config-role)# no vsan policy deny 

The following example permits this role to perform the allowed commands for VSANs 10 through 30.

switch(config-role)# permit vsan 10-30 

The following example removes the permission for this role to perform commands for vsan 15 to 20.

switch(config-role-vsan)# no permit vsan 15-20 

vrrp

To enable VRRP, use the vrrp command in configuration mode. Use the no form of the command to revert to the factory defaults or to negate a command.

vrrp vrrp-number
address ip-address [secondary] |
advertisement-interval seconds |
authentication {md5 keyname spi index | text password}|
preempt |
priority value |
shutdown |
track interface {mgmt 0 | vsan vsan-id}}

vrrp vrrp-number
no address ip-address [secondary] |
no advertisement-interval |
no authentication |
no preempt |
no priority |
no shutdown |
no track}

no vrrp vrrp-number

Syntax Description

address ip-address	Adds or removes an IP address to the virtual router.
secondary	Specifies a virtual IP address without an owner.
advertisement-interval seconds	Sets the time interval between advertisements. The range is 1 to 255.
authentication	Configures the authentication method.
md5 keyname	Sets the MD5 authentication key. Maximum length is 16 characters.
spi index	Sets the security parameter index. The range is 0x0 to 0xffffff.
text password	Sets an authentication password. Maximum length is 8 characters.
preempt	Enables preemption of lower priority master.
priority value	Configures the virtual router priority. The range is 1 to 254.
shutdown	Disables the VRRP configuration.
track	Tracks the availability of another interface.
interface	Select an interface to track.
mgmt 0	Specifies the management interface.
vsan vsan-id	Specifies a VSAN ID. The range is 1 to 4093.

Defaults

Disabled.

Command Modes

Interface configuration mode.

Command History

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

Usage Guidelines

Enter the Virtual Router configuration submode to access the options for this command. From the VSAN or mgmt0 (management) interface configuration submode, enter vrrp number to enter the switch(config-if-vrrp)# prompt. By default, a virtual router is always disabled (shutdown). VRRP can be configured only if this state is disabled. Be sure to configure at least one IP address before attempting to enable a VR.

Refer to the Cisco MDS 9000 Family Configuration Guide.

Examples

The following example enables VRRP configuration.

switch(config-if-vrrp)# no shutdown

The following example disables VRRP configuration.

switch(config-if-vrrp)# shutdown 

The following example configures an IP address for the selected VRRP.

switch# config terminal

switch(config)# interface vsan 1 

switch(config-if)# vrrp 250 

switch(config-if-vrrp)# address 10.0.0.10
