vlt-mac Configures a MAC address for all peer switches in a VLT domain. Syntax Parameters Default Command Mode Usage Information vlt-mac mac-address mac-address - Enter a MAC address for the topology in nn:nn:nn:nn:nn:nn format. Not configured VLT-DOMAIN 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 Parameters Default Command Mode Usage Information vrrp mode active-active None Enabled VLAN INTERFACE 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 Virtual Link Trunking 1435
