Congure the VLTi
Before you congure the VLTi on peer interfaces, remove each interface from L2 mode with the no switchport command. For more
information, see the VLT interconnect section.
1 Enter the VLT domain ID to enter from CONFIGURATION mode.
vlt-domain domain-id
2 Congure one or a hyphen-separated range of VLT peer interfaces to become a member of the VLTi in INTERFACE mode.
discovery-interface {ethernet node/slot/port[:subport] | ethernet node/slot/port[:subport] -
node/slot/port[:subport]}
3 Repeat the steps on the VLT peer.
Peer 1
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# no switchport
OS10(conf-if-eth1/1/1)# exit
OS10(config)# interface ethernet 1/1/2
OS10(conf-if-eth1/1/2)# no switchport
OS10(conf-if-eth1/1/2)# exit
OS10(config)# vlt-domain 1
OS10(conf-vlt-1)# discovery-interface ethernet1/1/1
OS10(conf-vlt-1)# discovery-interface ethernet1/1/2
Peer 2
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# no switchport
OS10(conf-if-eth1/1/1)# exit
OS10(config)# interface ethernet 1/1/2
OS10(conf-if-eth1/1/2)# no switchport
OS10(conf-if-eth1/1/2)# exit
OS10(config)# vlt-domain 1
OS10(conf-vlt-1)# discovery-interface ethernet1/1/1-1/1/2
Congure the VLT MAC address
You can manually congure the VLT MAC address.
Congure the same VLT MAC address on both the VLT peer switches to avoid any unpredictable behavior during a VLT failover. For
example, when a unit is down or when the VLTi is reset. If you do not congure a VLT MAC address, the MAC address of the primary peer
is used as the VLT MAC address across all peers.
Use the vlt-mac mac-address to congure the MAC address in both the VLT peers.
Example conguration:
OS10(config)# vlt-domain 1
OS10(conf-vlt-1)# vlt-mac 00:00:00:00:00:02
