Good grief! What the heck do you have running on that?? We have six
FastEthernet interfaces, seven T-1 interfaces running frame relay with a
total of about 150 PVCs, four ethernet interfaces, a VIP with an ATM
Port Adapter, huge access-lists, eigrp with lots of neighbors, two T1
point-to-point interfaces, policy routing, a CIP acting as a tn3270
server with hundreds of connections, ip accounting, etc..... and if our
router hits even 10% we freak out!
My suggestions:
1. If you have long access lists, turn on netflow switching on those
interfaces and also use Turbo ACLs (compiled access lists)
2. Use CEF and DCEF where you can, fast switching everywhere else.
3. Send us a copy of show proc cpu when the processor is really busy
so we can get a better idea of the cause.
4. Is this device being managed by some other device using SNMP?
Sometimes this can cause high CPU usage, but I haven't seen it happen on
an RSP before. What RSP are you using?
5. Use passive-interface statements to stop unnecessary routing
protocol traffic.
6. Check to see if someone turned on debugging and forgot to turn it
off.
Okay, that's all I can think off this early in the morning.
Good luck!

Greetings,
Any tips on improving high cpu utilization on a Cisco 7500?
4 T1s
1 HSSI
1 TokenRing Port
2 FastEthernet (Bundled, FEC)
Its running around 54%, any segmentations would be great.
Thanks,
Nabil
