NAME

       cisco_ios2dlf - convert cisco logs to dlf format

SYNOPSIS

       cisco_ios2dlf

DESCRIPTION

       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

        Aug 19 04:02:34 gateway.foo.bar 218963: Aug 19 04:02:32.977:
         %LINEPROTO-5-UPDOWN: Line protocol on Interface BRI0:1, changed state
         to down
        Aug 19 04:02:34 gateway.foo.bar 218964: Aug 19 04:02:33.262:
         %ISDN-6-DISCONNECT: Interface BRI0:1  disconnected from 172605440 acme,
         call lasted 42 seconds
        Aug 19 04:02:35 gateway.foo.bar 218965: Aug 19 04:02:33.266:
         %LINK-3-UPDOWN: Interface BRI0:1, changed state to down
        Aug 19 04:02:38 gateway.foo.bar 218966: Aug 19 04:02:36.103:
         %SEC-6-IPACCESSLOGP: list 102 denied tcp 100.198.139.148(4652) ->
         100.193.176.49(80), 1 packet
        Aug 19 04:02:45 gateway.foo.bar 218967: Aug 19 04:02:43.543:
         %ISDN-6-LAYER2DOWN: Layer 2 for Interface BR0, TEI 86 changed to down
        Aug 19 04:02:53 gateway.foo.bar 218968: Aug 19 04:02:51.471:
         %SEC-6-IPACCESSLOGP: list 102 denied tcp 100.74.103.1(2162) ->
         100.193.176.98(80), 1 packet

       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
