Perplexed by something . I'm trying to clean up some 2950 L2 switch configs. On all switches, a predecessor configured snmp and syslog logging, but the configs reference a non-existent server IP address. That's fine - I can just change the address to the correct one. But what is baffling me is that syslog and snmp are already both receiving information from the switches (confirmed with Wireshark). In other words, before changing anything in the configs, I wanted to confirm the problem and looked at data on the installed Cisco Network Assistant on the correct server. And I see that syslog and snmp are both receiving info from the switches. And the logged entries are current. My question is 'How can this be?'. How can an snmp or Syslog server get information from an agent device that is incorrectly configured? Could it be that an SNMP community is all that is needed on an agent (and not snmp-server host)? (Doesn't explain the syslog).
Thank you for any help you can provide.
