vlt-port-channel
Congures the ID used to map interfaces on VLT peers into a single VLT port-channel.
Syntax
vlt-port-channel vlt-lag-id
Parameters vlt-lag-id — Enter a VLT port-channel ID, from 1 to 1024.
Default Not congured
Command Mode PORT-CHANNEL INTERFACE
Usage Information Assign the same VLT port-channel ID to interfaces on VLT peers to create a VLT port-channel. The no version of
this command removes the VLT port-channel ID conguration.
Example (peer 1)
OS10(conf-if-po-10)# vlt-port-channel 1
Example (peer 2)
OS10(conf-if-po-20)# vlt-port-channel 1
Supported Releases 10.2.0E or later
vlt-mac
Congures a MAC address for all peer switches in a VLT domain.
Syntax
vlt-mac mac-address
Parameters mac-address — Enter a MAC address for the topology in nn:nn:nn:nn:nn:nn format.
Default Not congured
Command Mode VLT-DOMAIN
Usage Information Use this command to minimize the time required to synchronize the default MAC address of the VLT domain on
both peer devices when one peer switch reboots. 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. This conguration must be symmetrical in all the
peer switches to avoid any unpredictable behavior. For example, unit down or VLTi reset. The no version of this
command disables the VLT MAC address conguration.
NOTE: Congure the VLT MAC address as symmetrical in all the VLT peer switches to avoid any
unpredictable behavior when any unit is down or when VLTi is reset.
Example
OS10(conf-vlt-1)# vlt-mac 00:00:00:00:00:02
Supported Releases 10.2.0E or later
