A 20 year old codebase and Cisco’s indifference to making the SNMP code any better, most likely.

Ok, this is weird. This what all my ASA’s look like as far as ports: [cid:image001.jpg@01DA4EE2.0A463680]
I have disabled polling on the ones I do not need….but the performance data shows this: [cid:image002.jpg@01DA4EE2.0A463680]
Why do ports take so long when there are so few?

I’d say before changing maxreps go to the device and go to the gear-->Performance data and see which module(s) are taking the longest.
If they’re ones you don’t care about you can disable them for that device.

This can happen when a device has a large number of interfaces and/or the device is a long way away (ping time). Also, the snmp poller only collects 10 items at a time which is compatible with everything. However some devices can handle collecting many more items at a time.
Go into Device Properties, SNMP tab and set "Max Repetitions" to a higher number, say 50 or 100.

While all my other infrastructure seems to poll about 5 to 7 sec per device, the ASA’s all take 50 to 60 sec.
Does anyone know why this is and maybe how to speed things up?
Thanks
