192.168.19.1 - 1

994118619 permitted udp 192.168.19.1 138 Serial0/0.2 DLCI_120

192.168.19.255 138 1

EXAMPLES

To process a log as produced by Cisco IOS:: $ cisco_ios2dlf < cisco.log
cisco_ios2dlf will be rarely used on its own, but is more likely called by lr_log2report:: $ lr_log2report cisco_ios < /var/log/cisco.log
