I am new to the open source network access control solution called Packetfence.
I am currently diagnosing Packetfence log files remotely.
The network seemed to be running smoothly with Packetfence, until around the 5th-6th of March. Now, when the Packetfence service is started, the network on the destination stops working.
There are 50+ switches and 500+ PCs and devices that access the network so it is not possible to diagnose this issue in other ways than looking at log files.
Some errors from the log file:
Mar 05 17:14:34 pfsetvlan(22) ERROR: error creating SNMP v2c read connection to 172.17.250.19: No response from remote host '172.17.250.19' (pf::SNMP::connectRead)
ERROR: could not convert dot1dBasePort into ifIndex in any VLAN. Setting trapType to unknown (pf::SNMP::Cisco::parseTrap)

Mar 06 08:41:04 pfdhcplistener(3617) INFO: could not resolve 172.17.4.120 to mac in ARP table (pf::iplog::ip2macinarp)
- Why do these error messages occur?
- What can I do to continue searching for the problem?
