VLTi conguration
Before you congure 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 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
OS10(conf-vlt-1)# discovery-interface ethernet1/1/2
Congure VLT MAC address
You can manually congure the VLT MAC address.
Congure the VLT MAC address symmetrical in both the VLT peer switches to avoid any unpredictable behavior when any unit is down or
when 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. Conguring the MAC address manually enables to minimize the time required to synchronize the default MAC address of
the VLT domain on both peer devices when one peer switch reboots.
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
NOTE
: It is recommended to congure the same VLT MAC address manually on both the VLT peer switches.
