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
Supported
Releases
10.2.0E or later
