Are your network management people stating that they are
experiencing timeouts when attempting to communicate to
your 7500, or through your 7500?
I doubt the 7500 is going to be upset about passing UDP traffic
through it. The router should just forward the traffic, generally
speaking, the router doesn't care what kind of traffic it is.
However, an SNMP query must be processed by the RSP, and requires
an interrupt. A large amount of interrupts is going to cause
slowdowns, and SNMP timeouts are possible. If they are doing
large amounts of queries on the box, you might want to look
into the following links:
http://www.cisco.com/warp/public/63/highcpu.html
http://www.cisco.com/warp/public/477/SNMP/ipsnmphighcpu.shtml
http://www.cisco.com/warp/public/477/SNMP/collect_cpu_util_snmp.html
As well as getting with your network management people to
see just why in the world they need to pound your 7500
with SNMP queries.
If that still doesn't help, it'd be handy to pull out
a sniffer, or use tcpdump/snoop on the box making all
those SNMP requests. See just what its sending the messages
to, etc...

Subject: Traffic geneartor for SNMP [7:51172]
Hi,
Anybody know any traffic geneartor which is available for testing the snmp
traffic.
I am having a lab configuration with cisco 7500 router and the network
management people are syaing that there are lot of SNMP timeouts.
I want to pump in lot of UDP packets on to the network and see whether it's
the problem of the network?
How can u see the udp problem in Cisco routers?
Is there any command to see that?
How will you see the CPU utilization of the routers?
Is there any command?
Any help appreciated.
