list FR_VA_in permitted udp 192.168.19.1(137) (Serial0/0.2 DLCI 120)

The outputted dlf files look like:
994118619 permitted icmp 192.168.80.9 - Serial0/0.2 DLCI_120
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
