CatOS experts? Need snmp/rmon help..

[mlew]

I am trying to set interface packet thresholds and report an alarm or event when this threshold exceeds the limit. Now, for IOS I am using the following line from #sh int fa XX:

5 minute input rate 30000 bits/sec, 58 packets/sec

or

rmon alarm 1 lifEntry.9.23 10 absolute rising-threshold 200 1 falling-threshold

100 2 owner Marcelo

HOW can I get similar results with CatOS (2948G and 2980G)? I see that my software version (CatOS 6.4.X) has the RMON-MIB (RFC 1757), which allows me to see that output on my IOS switches with an SNMP viewer (What’s Up Gold in my case). Is there a 5-minute output for packets, bits, or something in CatOS?

Thanks for the help.

Unfortunately, there's no CLI to configure RMON alarms and events on CatOS. You will have to use snmpset to accomplish this.

Thank you, I will give this a try.

Do you know much about CiscoWorks? Is there a way to ckeck packet output with CW, not just overall bandwidth utilization? (that's what I found on DFM)

Thanks again.

CV can do some basic monitoring, but it only shows you total packets per second, not just output. The best shot is open source tools, MRTG and Cricket. You can always poll ifOutOctets or ifHCOutOctets using any snmpwalk tools.

"You can always poll ifOutOctets or ifHCOutOctets using any snmpwalk tools"

What MIB object shall I use for 5 min snapshots on CatOS? What is HCOutOctets? Because ifOutOctets is a cumulative count, right?

Thanks.
