Command History

Release
Modified

1.0(2)

This command was introduced.

3.0(1)

•Added the IPv6 option.

•Added the address and advertisement-interval options that are specific to IPv6.


Usage Guidelines

You 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 virtual router.

The total number of of VRRP groups that can be configured on a Gigabit Ethernet port, including main interfaces and subinterfaces, cannot exceed seven. This limitation applies to both IPv4 and IPv6 groups.

Note If you configure secondary VRRP IPv6 addresses on an IPFC VSAN interface, you must remove the secondary VRRP IPv6 addresses before downgrading to a release prior to Cisco Release 3.0(1). This is required only when you configure IPv6 addresses.

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 IPv4 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

vsan (iSCSI initiator configuration and iSLB initiator configuration)

To assign an iSCSI or iSLB initiator to a VSAN other than the default VSAN, use the vsan command in iSCSI initiator configuration submode or iSLB initiator configuration submode. To disable this feature, use the no form of the command.

vsan vsan-id

no vsan vsan-id

Syntax Description

Modification

1.3(2)

This command was introduced.

3.0(1)

Added iSLB initiator configuration submode.


Usage Guidelines

When you configure an iSLB initiator in a VSAN other than VSAN 1 (the default VSAN), the initiator is automatically removed from VSAN 1. For example, if you configure an iSLB initiator in VSAN 2 and you also want it to be present in VSAN 1, you must explicitly configure the initiator in VSAN 1.

Examples

The following example assigns an iSCSI initiator to a VSAN other than the default VSAN: 

switch# config terminal 

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

switch(config)# iscsi initiator name iqn.1987-02.com.cisco.initiator

switch(config-iscsi-init)# vsan 40

switch(config-iscsi-init)#

The following example assigns an iSLB initiator to a VSAN other than the default VSAN: 

switch# config t

switch(config)# islb initiator ip-address 100.10.10.10

ips-hac2(config-islb-init)# vsan ?

<1-4093> Enter VSAN

ips-hac2(config-islb-init)# vsan 10


The following example removes the iSLB initiator: 

switch (config-islb-init)# no vsan 10

To remove a configuration, use the no command in VSAN database submode.

vsan database vsan vsan-id [interface fc slot/port | fcip fcip-id | fv slot/dpp-number/fv-port | iscsi slot/port | port-channel portchannel-number.subinterface-number} | interop [mode] [loadbalancing {src-dst-id | src-dst-ox-id}] | loadbalancing {src-dst-id | src-dst-ox-id} | name name [interop [mode] [loadbalancing {src-dst-id | src-dst-ox-id}] | loadbalancing {src-dst-id | src-dst-ox-id} | suspend [interop [mode] [loadbalancing {src-dst-id | src-dst-ox-id}] | loadbalancing {src-dst-id | src-dst-ox-id}] | suspend [interop [mode] [loadbalancing {src-dst-id | src-dst-ox-id}] | loadbalancing {src-dst-id | src-dst-ox-id}]]

Command History

Release
Modification

1.2(2)

This command was introduced.

3.0(1)

Increased the interop mode range to 4.

3.1(2)

Added the interface bay | ext option.


Usage Guidelines

Change to 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)

There are four interop modes:

•Interop mode 1 - Standards based interop mode that requires all other vendors in the fabric to be in interop mode.

•Interop mode 2 - Brocade native mode (Core PID 0).

•Interop mode 3 - Brocade native mode (Core PID 1).

•Interop mode 4 - McData native mode.

Note Before you configure Interop mode 4 (or remove the configuration), you must suspend the VSAN. You should unsuspend the VSAN only after you configure a VSAN-dependent switch WWN with the McData OUI [08:00:88].

Examples

The following examples show how to create multiple fabrics sharing the same physical infrastructure and how to assign ports to VSANs: 

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 

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

switch(config-vsan-db)# vsan 2 suspend 

switch(config-vsan-db)# no vsan 2 suspend

switch(config-vsan-db)# vsan 2 interface fv2/8/2

switch(config-vsan-db)# vsan 2 interface iscsi 2/1

switch(config-vsan-db)# end

switch#

The following example shows how to suspend a VSAN and enable interop mode 4: 

switch# config t

switch(config)# vsan database

switch(config-vsan-db)# vsan 100 suspend

switch(config-vsan-db)# vsan 100 interop 4

switch(config-vsan-db)# exit

Command
Description

vsan wwn

Configures a WWN for a suspended VSAN that has interop mode 4 enabled.


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

no vsan policy deny permit vsan vsan-id

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

Release
Modification

1.2(1)

This command was introduced.


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
