Enabling the GLBP Feature

You must enable the GLBP feature before you can configure and enable any GLBP groups.
BEFORE YOU BEGIN
Ensure that you are in the correct VDC (or use the switchto vdc command).
OL-20002-02
You should configure all customization options for GLBP on all GLBP member gateways before
enabling a GLBP group by configuring a virtual IP address.
You must configure an IP address for the interface that you configure GLBP on and enable that
interface before GLBP becomes active.
The GLBP virtual IP address must be in the same subnet as the interface IP address.
We recommend that you do not configure more than one first-hop redundancy protocol on the same
interface.
Cisco NX-OS removes all layer 3 configuration on an interface when you change the VDC, interface
VRF membership, port channel membership, or when you change the port mode to layer 2.
Cisco NX-OS does not support GLBP group configuration on interface secondary subnets.
