I appear to have issues with receiving MAC addresses via SNMP Trap from a Cisco WLC, they end up as garbage in the resulting JSON.
I have verified several things based on similar posts
- The MAC address is valid in the tcpdump
- I'm running the latest version of logstash that fixed a similar issue
- I've tried both queuing methods (memory and persisted)
- I've set codec => plain & charset => ASCII-8BIT
Any help would be greatly appreciated.
