vsan database
To create multiple fabrics sharing the same physical infrastructure, to assign which ports are in which VSAN, whether Interop mode is on or off, and whether load balancing is per exchange or src-dest ID., use the vsan command.
vsan database [exit] [no] [vsan vsan-id interface fc slot-number | port-channel port-number]
[vsan vsan-id interop loadbalancing src-dst-id | src-dst-ox-id] [vsan vsan-id loadbalancing
src-dst-id | src-dst-ox-id] [vsan vsan-id name name interop loadbalancing src-dst-id |
src-dst-ox-id] [vsan vsan-id name name loadbalancing src-dst-id | src-dst-ox-id] [vsan
vsan-id suspend interop | loadbalancing] [vsan vsan-id suspend]
Syntax Description
exit
|
Exits from submode.
|
no
|
Negates a command or sets its defaults.
|
vsan
|
Configures VSAN information or membership.
|
vsan-id
|
The ID of the VSAN is from 1 to 4093.
|
interface
|
Adds interfaces to VSAN.
|
fc
|
Configures Fiber Channel interface.
|
slot_number
|
Specifies a slot number and port number.
|
port-channel
|
Configures PortChannel interface.
|
port-number
|
Specifies PortChannel number.
|
interop
|
Turns on interoperability mode.
|
loadbalancing
|
Configures loadbalancing scheme.
|
src-dst-id
|
Sets src-id/dst-id for loadbalancing.
|
src-dst-ox-id
|
Sets ox-id/src-id/dst-id for loadbalancing (default).
|
suspend
|
Suspends VSAN.
|
Defaults
None.
Command Modes
Configuration mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(2).
Usage Guidelines
Change to the VSAN database submode to issue this command.
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)# vsan database
switch(config-vsan-db)# vsan 2 name TechDoc
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)# end
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 vsan-id ]
no vsan policy deny {permit vsan vsan vsan-id ]
Syntax Description
vsan policy deny
|
Configures VSAN based roles.
|
vsan-id
|
The ID of the VSAN is from 1 to 4093.
|
permit
|
Remove commands from the role.
|
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)# role name sangroup
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
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 | advertisement-interval | authentication | preempt | priority | shutdown | track]
no vrrp vrrp-number
[address | advertisement-interval | authentication | preempt | priority | shutdown | track]
Syntax Description
vrrp vrrp-number
|
Configures a VRRP on the selected VSAN or management interface
|
address
|
Adds or removes an IP address to the virtual router.
|
advertisement-interval
|
Sets the time interval between advertisements.
|
authentication
|
Sets the authentication method.
|
preempt
|
Enables preemption of lower priority master.
|
priority
|
[1-254] Configure the virtual router priority.
|
shutdown
|
Enables or disables a virtual router.
|
track
|
Tracks the availability of another interface.
|
Defaults
Disabled.
Command Modes
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)# interface vsan 1
switch(config-if)# vrrp 250
switch(config-if-vrrp)# address 10.0.0.10
