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 configuration.
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
Configures 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 configured
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 configure a VLT MAC address,
the MAC address of the primary peer is used as the VLT MAC address across all peers. This configuration
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 configuration.
NOTE: Configure 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
vrrp mode active-active
Enables the VRRP peers to locally forward L3 traffic in a VLAN interface.
Syntax
vrrp mode active-active
Parameters None
Default Enabled
Command Mode VLAN INTERFACE
Usage
Information
This command is applicable only for VLAN interfaces.
In a non-VLT network, the backup VRRP gateway forwards L3 traffic. If you want to use VRRP groups on
VLANs without VLT topology, disable the Active-Active functionality, to ensure that only the active VRRP
gateway forwards L3 traffic.
The no version of this command disables the configuration.
Example
OS10(conf-if-vl-10)# vrrp mode active-active
