GEIP+ and Cisco 7505

Unanswered Question
Apr 16th, 2009

Is there a limit on number of GEIP+ that can be used in a 7505 chassis? (other then slots)

Also is there a limit that can be used with a RSP4 and RSP16?


I have this problem too.

Hello Dan,

an advice:

performance of GEIP+ are far lower then declared consider them as a way to provide a GE port to the device.

With small packets capabilities for us were in the order of less then 100 Mbps

With big packets we could achieve up to 260-280 Mbps.

A c7505 should have a single Cybus running at 1Gbps : a shared bus for all linecards/VIPs

All packets are actually moved via MEMD that is on the RSP (for the legacy cards) so the platform is not really distributed.

If you look for performance it is better to look at othe platforms:

a C7200 with NPE-G1 or NPE-G2 behaves better just to say.

C7500 has been a very good router, but now its performances are too low for most applications.

Hope to help
