Connecting a VLT Domain to an Attached Access Device (Switch or
Server)
To connect a VLT domain to an attached access device, use the following commands.
On a VLT peer switch: To connect to an attached device, configure the same port channel ID number on each peer switch in the VLT
domain.
1 Configure the same port channel to be used to connect to an attached device and enter interface configuration mode.
CONFIGURATION mode
interface port-channel id-number
2 Remove an IP address from the interface.
INTERFACE PORT-CHANNEL mode
no ip address
3 Place the interface in Layer 2 mode.
INTERFACE PORT-CHANNEL mode
switchport
4 Add one or more port interfaces to the port channel.
INTERFACE PORT-CHANNEL mode
channel-member interface
interface: specify one of the following interface types:
• For a 1-GigabitEthernet interface, enter the keyword GigabitEthernet then the slot/port information.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information.
5 Ensure that the port channel is active.
INTERFACE PORT-CHANNEL mode
no shutdown
6 Associate the port channel to the corresponding port channel in the VLT peer for the VLT connection to an attached device.
INTERFACE PORT-CHANNEL mode
vlt-peer-lag port-channel id-number
7 Repeat Steps 1 to 6 on the VLT peer switch to configure the same port channel as part of the VLT domain.
8 On an attached switch or server: To connect to the VLT domain and add port channels to it, configure a port channel. For an example
of how to verify the port-channel configuration, refer to
To configure the VLAN where a VLT peer forwards received packets over the VLTi from an adjacent VLT peer that is down, use the peer-
down-vlan parameter. When a VLT peer with BMP reboots, untagged DHCP discover packets are sent to the peer over the VLTi. Using
this configuration ensures the DHCP discover packets are forwarded to the VLAN that has the DHCP server.
Configuring a VLT VLAN Peer-Down (Optional)
To configure a VLT VLAN peer-down, use the following commands.
1 Enter VLT-domain configuration mode for a specified VLT domain.
CONFIGURATION mode
vlt domain domain-id
