SYNOPSIS
cisco_ios2dlfDESCRIPTION
This script expects syslog-type logs from a CISCO IOS router on stdin. These look like e.g.
Jul 3 00:00:39 router 40108: 4d09h: %SEC-6-IPACCESSLOGP: list FR_VA_in permitted udp 192.168.19.1(137) (Serial0/0.2 DLCI 120) -> 192.168.19.255(137), 2 packets Jul 3 00:02:39 router 40109: 4d09h: %SEC-6-IPACCESSLOGP: list FR_VA_in permitted udp 192.168.80.42(138) (Serial0/0.2 DLCI 120) -> 192.60.60.148(138), 1 packet Jul 3 00:02:39 router 40110: 4d09h: %SEC-6-IPACCESSLOGDP: list FR_VA_in permitted icmp 192.168.80.82 (Serial0/0.2 DLCI 120) -> 149.1.1.1 (8/0), 1 packet
or

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
