Interface SNMP info not matching CLI output

branfarm

I have an SVI on a Catalyst 6500 that is showing an transmit rate of 175Mbps in Orion, but the CLI output shows a 5 minute output rate of 0 bits/sec.  This particular interface only receives Dense mode multicast groups, and there's an output ACL that blocks almost all outbound traffic on the interface.  If the ACL wasn't there, I think the 175Mbps might be accurate due to some other dense mode traffic that would be flooded out the interface.  Does the SNMP data get stored before the ACL is applied to the traffic?

 

Thanks,

Not sure, this is a Cisco question, but a good way to test that is to take a MIB Walk of what the agent  returns and to compare with the CLI output, and also compare with what NPM shows (at approx. the same time of course).

Whatever NPM shows but be ~= to the SNMP walk. Otherwise it's a bug.

You can use this procedure or whatever MIB browser (from Eng Toolset for ex.)

 Please download and install net-snmp from http://net-snmp.sourceforge.net/

You can download the Win32 binaries here: http://sourceforge.net/projects/net-snmp/files/net-snmp binaries/5.5-binaries/net-snmp-5.5.0-1.x86.exe/download

It doesn’t matter what machine do you install it on, as long as it reaches the device.

Run this command from “installation directory/bin/”: snmpwalk -v 2c -c public -O netU 127.0.0.1 1 > output.txt

(change the IP address and community string accordingly)

Pack the file output.txt into zip archive and send it.
