Create VLT domain
A VLT domain requires an ID number. Configure the same VLT domain ID on both peers. For more information, see VLT domain.
The no vlt-domain command disables VLT.
1. Configure a VLT domain and enter VLT-DOMAIN mode. Configure the same VLT domain ID on each peer, from 1 to 255.
vlt-domain domain-id
2. Repeat the steps on the VLT peer to create the VLT domain.
Peer 1
OS10(config)# vlt-domain 1
OS10(conf-vlt-1)#
Peer 2
OS10(config)# vlt-domain 1
OS10(conf-vlt-1)#
VLTi configuration
Before you configure VLTi on peer interfaces, remove each interface from L2 mode with the no switchport command. For
more information, see VLT interconnect.
1. Enter the VLT domain ID to enter from CONFIGURATION mode.
vlt-domain domain-id
2. Configure 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
