[cisco-bba] 7206vxr High cpu usage

[Frank Bulk]

Wayne:

Please post a copy of "sh proc cpu | exc 0.00.*0.00" 

Also, if you can capture a copy of: 
	show ip traffic
	sh ip interface
	show interfaces switching
and post that somewhere we'll likely see something to get you started on.

Regards,
 
Frank

Subject: [cisco-bba] 7206vxr High cpu usage

Hello.

I have high CPU usage on our 7206VXR NPE-G1 with 1 gig of memory.
We are using this router for PPPoA Broadband and also BGP for internet
traffic.

Current IOS ver =  (C7200-IS-M), Version 12.3(6b)
Current online users = 1845
Current BGP neighbours (full routes) = 5
Current mem usage (5 minute avg) = 292 meg
Current CPU usgae (5 min avg) = 26%
Current total throughput in = 91.09 bits per sec
Current total throughput out =     95.46 bit per sec

I've been reading the list and following the threads on high CPU usage,
we have no compression applied to the Virtual-Access interfaces. I'm
out of my depth here so any help would be appreceated.
