14.1.1 Introduction to GSRP

Gigabit Switch Redundancy Protocol (GSRP) provides redundancy for the Switch by securing a communication path via another switch in the same network even if the primary switch has failed.

Spanning Tree Protocols provide redundancy for the network. However, because GSRP is controlled between two switches, switching between switches is faster than between Spanning Tree Protocols. GSRP is also suitable for large-scale configurations in which core switches are used in multiple stages on a network.

The following figure provides an overview of redundancy in Layer 2 provided by GSRP.

Figure 14-1 Overview of GSRP

The Switch supports GSRP aware. GSRP aware clears MAC address table of the local switch by receiving control frames from GSRP switch.. GSRP aware is not set by a configuration command.
