Other Devices

The following table summarizes how other network devices see two ASR 5000s chassis during online upgrade. The

table below assumes that a SRP-activated loopback address is configured in the source (toward the MS), the destination

(toward the HA), and the AAA contexts (Diameter and RADIUS).

Consideration in Two-Chassis Configuration

This L3 switch sees two chassis as a single entity. Only the physical port in the switch changes due to the

switchover operation by G-ARP. The rest of the ASR 5000 information (IP address and MAC address) remain the

The MS sees two PDIFs as the same entity. However, upon switchover the SCTP connection is disconnected and

then a new SCTP connection with ASR 5000 is established immediately.If an L3 switch exists between the PDIF

and Diameter server, it sees two chassis as a single entity. Only the physical port in the switch changes due to the

switchover operation by IPv6 Unsolicited Neighbor Advertisement. The rest of the ASR 5000 information (IP

address and MAC address) remains the same.
