MLAG Partner Switch Configuration
1 Configure partner switch 1 with a port-channel connected to the MLAG
aware switches.
console#config
console(config)#interface Gi1/0/19
console(config-if-Gi1/0/19)#channel-group 1 mode active
console(config-if-Gi1/0/19)#no keepalive
console(config-if-Gi1/0/19)#exit
console(config)#interface Gi1/0/24
console(config-if-Gi1/0/24)#channel-group 1 mode active
console(config-if-Gi1/0/24)#no keepalive
console(config-if-Gi1/0/24)#exit
console(config)#interface port-channel 1
console(config-if-Po1)#switchport mode trunk
console(config-if-Po1)#exit
2 Disable the loop protect feature on all the interfaces (optional).
console(config)#interface range gigabitethernet all
console(config-if)#no keepalive
console(config-if)#exit
3 Configure spanning-tree mode as RPVST.
console(config)#spanning-tree mode rapid-pvst
4 Create VLAN-2 for voice traffic. This configuration must be the same as
on the MLAG aware switches.
console(config)#vlan 2
console(config-vlan-2)#exit
5 Enable Voice VLAN globally.
console(config)#voice vlan
6 Configure the VoIP phone connected port. The Voice VLAN assignment
must be the same on all switches.
console(config)#interface Gi2/0/11
console(config-if-Gi2/0/11)#switchport mode access
console(config-if-Gi2/0/11)#voice vlan 2
console(config-if-Gi2/0/11)#exit
7 Configure egress queue 2 as strict. By default, the VoIP phone sends voice
traffic with 802.1p priority 5, which is mapped to egress queue 2 by
default.
