Configuring a service VF instance
Configuring a service VF instance consists of enabling VF configuration in the fabric, and then
configuring a service VF instance that is greater than 4095, The initial release of this feature supports
up through 8192 VLANs, with 8191 being the largest number that can be assigned.
The vcs virtual-fabric enable command , issued in global configuration mode, expands the VLAN ID
address space beyond the 802.1Q limit in the fabric, allowing VLANs with IDs greater than 4095 to be
supported, up through 8191. The command, which is accepted only if the state of the fabric is capable
of supporting VLAN virtualization, does not disrupt existing 802.1Q data traffic in the fabric.
Enabling service VF configuration
In global configuration mode, issue the vcs virtual-fabric enable command:
switch(config)# vcs virtual-fabric enable
NOTE
Use the no form of this command to disable service VF configuration.
Creating a service VF instance
In global configuration mode, use the interface vlan vlan_id command, where vlan_id is a number
greater than 4095, through 8191, and is not a reserved VLAN.
switch(config)# interface vlan 5000
NOTE
Use no interface vlan vlan to delete a service VF.
Configuring a transport VF instance
The following example command sequence illustrates the configuration of three transport VF
instances.
switch(config)# interface vlan 6001
switch(config-Vlan-6001)# transport-service 1
switch(config)# interface vlan 6002
switch(config-Vlan-6002)# transport-service 2
switch(config)# interface vlan 6003
switch(config-Vlan-6003)# transport-service 3
Configuring VF classification to a trunk interface
The following example command sequence illustrates the configuration of VF classification to a trunk
interface.
switch(config)# interface TenGigabitEthernet 1/0/1
switch(conf-if-te-1/0/1)# switchport
switch(conf-if-te-1/0/1)# switchport mode trunk
switch(conf-if-te-1/0/1)# switchport trunk allowed vlan add 5000 ctag 100
switch(conf-if-te-1/0/1)# switchport trunk allowed vlan add 5001 ctag 101
