64 bit interface?

Hi everyone, I am configuring an NMS software (Zenoss) to work with my Cisco devices. In Zenoss there is an option to set alerting for 32-bit or 64-bit ethernet interfaces. Would Cisco interfaces be considered 32-bit or 64-bit?

It depends on the speed of the interface, not the type of device.

SNMP version 1 supports only 32 bit counters - which means that for 1 gig (or faster) interfaces, you don't get a "true" indication of utilisation or speed.

If your device only supports SNMP version 1, then it's a 32 bit device as far as your NMS software is concerned. if your device supports (and has enabled) SNMP v2 or SNMP v3, then it's a 64 bit device as far as your NMS is concerned.

Most Cisco modern Cisco devices support SNMP v1/2c/3, so they're all "64 bit" devices, provided you have enabled the appropriate level of SNMP on your device.

Cheers.

I'm not familiar with the software, but you can see what processor your appliance is equipped with by running show version

For example, on a 2950 switch, midway through the show version would read:

"cisco WS-C2950-24 (RC32300) processor (revision R0) with 21039K bytes of memory."

A quick search shows that the RC32300 is a 32 bit processor. In fact, the 32 after RC designated 32 bit archeticture and the 64 bit family is named RC64xxx

Is the question 32 or 64 bit SNMP MIB counters?
