- Configuring device redundancy using VSRP
Virtual Switch Redundancy Protocol (VSRP) provides device redundancy for specific ports in a port-based VLAN. Configuring VSRP device redundancy in your network leads to faster failover times if an interface goes offline. - Configuring optional VSRP parameters
You can configure several optional VSRP parameters. - Configuring authentication on VSRP interfaces
If the interfaces on which you configure the VRID use authentication, the VSRP packets on those interfaces also must use the same authentication. - Tracking ports and setting the VSRP priority
Configuring port tracking on an exit path interface and setting a priority on a VSRP device enables VSRP to monitor the interface. If the interface goes down, the VRID’s VSRP priority is reduced by the amount of the track port priority you specify. - Disabling backup pre-emption setting
- VSRP-aware security features
- VSRP fast start
