Grab Option 82 data from DHCP syslogs
Today's Mission:
One of my customer wants to grab Option 82 data from DHCP syslog servers. So we have the Switch name in the "circuit-id" and then rename the new switch with that information.
Here is the data:
('10.10.10.53 : ', '<30>Nov 12 15:02:13 10.10.10.53 dhcpd[27476]: Option 82: received a REQUEST DHCP packet from relay-agent 10.10.10.97 with a circuit-id of "MyTestSwitch-A" for 10.10.10.100 (0:26:51:30:ca:41) lease time is undefined seconds.')
('10.10.10.53 : ', '<30>Nov 12 15:02:13 10.10.10.53 dhcpd[27476]: DHCPDISCOVER from 00:26:51:30:ca:41 via 10.10.10.97 uid 00:63:69:73:63:6f:2d:30:30:32:36:2e:35:31:33:30:2e:63:61:34')
