Information About GIR
You can use Graceful Insertion and Removal (GIR) to isolate a switch from the network in order to perform
debugging or an upgrade. When switch maintenance is complete, you can return the switch to normal mode.
When you place the switch in maintenance mode, all protocols are gracefully brought down and all physical
ports are shut down. When normal mode is restored, all the protocols and ports are brought back up.
The following protocols are supported:
• Border Gateway Protocol (BGP)
• BGPv6
• Enhanced Interior Gateway Routing Protocol (EIGRP)
• EIGRPv6
• Intermediate System-to-Intermediate System (ISIS)
