LMS 2.6 changed SNMP Communities cause errors

netzeatkw · ‎11-25-2009

Hello,

we use LMS 2.6 with CS 3.0.6 and SNMP v1. A small part of CiscoWorks's SNMP requests cause Authentication errors on network devices which are correct when I test the device cedential verification. A sniffer trace shows some malformed packets with SNMP community names of the form community@21 with suffixes @nn. All other packet contain the unchanged community name and are working well.

Any idea how we can fix this?

Thanks in advance

These queries come from Campus Manager when querying per-VLAN data for spanning-tree and end hosts (i.e. User Tracking). You will need to provide the entire packet in order to know which function in Campus Manager is performing this polling. Based on that, steps can be taken to mitigate the problem.
