Metarouter with SNMP crashes on RB1100AH

by Wazza » Wed Feb 22, 2012 2:42 pm

Hi,

I've got several RB1100AH's that we're using for Metarouters. We need SNMP to work on these things, however whenever we enable it in the metarouter, the terminal hangs / crashes. Same deal under Winbox.

Tested on several different RB1100AH's, with RouterOS 5.12 and consistently fails.

I've tried under 5.13, and it does seem to work there, but the ethernet interfaces flap, which prevents me from switching to that version.

Any thoughts on this?

Thanks,

Wazza.

I've got same problem. When I opened the snmp settings window, the (meta)router logged this error to the console:
