Question

Using KIWI Syslog server with Cisco router but no messages are being logged?

Asked by: dealvis

Using KIWI Syslog server for Cisco 1720 router logging but no messages are being logged except for when I use the IOS command "logging trap XXXX" command to change the logging level?

Cisco 1720 Router is perimeter router out in front of PIX FW.
rtr1720#show ver                
Cisco Internetwork Operating System Software                                            
IOS (tm) C1700 Software (C1700-Y-M), Version 12.1(3)XT2, EARLY DEPLOYMENT RELEAS                                                                                
E SOFTWARE (fc1)


KIWI Syslog Daemon V8.0.2 (with trial license key installed) is running on Admin Workstation PC on internal LAN.

I think I have ruled out PIX because I do see an entry appear in the KIWI Syslog server display from the Cisco 1720 router when I change the logging level on the 1720 Router from "INFORMATIONAL" to "DEBUGGING" using the

 -> rtr1720(config)#logging trap debugging

command that looks like this:

08-07-2006    17:18:08  Local7.Notice    209.43.17.1    40:Aug 7 22:18:12: %SYS-5-CONFIG_I: Configured from console by Admin on console

  I think I am missing something in router logging configuration?  Here it is, can an Expert take a look?

rtr1720#show logging
Syslog logging: enabled (0 messages dropped, 1 messages rate-limited, 6 flushes,
 0 overruns)
    Console logging: disabled
    Monitor logging: disabled
    Buffer logging: level debugging, 7 messages logged
    Logging Exception size (0 bytes)
    Trap logging: level debugging, 40 message lines logged
        Logging to 209.43.17.61, 7 message lines logged

Log Buffer (4096 bytes):

Aug  5 23:27:42: %SYS-5-CONFIG_I: Configured from console by suldao on console
Aug  5 23:31:56: %SYS-5-CONFIG_I: Configured from console by suldao on console
Aug  5 23:35:32: %SYS-5-CONFIG_I: Configured from console by suldao on console
Aug  6 00:19:45: %SYS-5-CONFIG_I: Configured from console by suldao on console
Aug  6 00:28:42: %SYS-5-CONFIG_I: Configured from console by suldao on console
Aug  6 00:32:10: %SYS-5-CONFIG_I: Configured from console by suldao on console
Aug  6 00:32:51: %SYS-5-CONFIG_I: Configured from console by suldao on console
rtr1720#


Note that the Admin PC running KIWI Syslog server is on the internal LAN behind the INSIDE interface of the PIX and has the address 192.168.0.9

I used a static command and an ACL entry on the PIX to facilitate the syslog messages from the router (209.43.17.1) on the "OUTSIDE" to reach the PC running the Syslog server on the "INSIDE".  Again, my assumption is I did this correctly or the entry that does appear from the router as shown above would never show, right?

Hi,

All you need for syslogging is really the host ip address.  Such as, for example:

router#conf t
router(config)#service timestamps log datetime msec
router(config)#service timestamps debug datetime msec
router(config)#logging x.x.x.x (this will be the syslog server)
router(config)#logging trap <0 - 7>  (To set from Emergency through to Debug)

Dont get confused with SNMP traps, which are a slightly different thing.

Cheers

Sorry Mr. Mohawk I am not following?

I already used those IOS commands on the Cisco 1720 router but the only log message that shows up on the KIWI Syslog server is:

08-07-2006    17:18:08  Local7.Notice    209.43.17.1    40:Aug 7 22:18:12: %SYS-5-CONFIG_I: Configured from console by Admin on console

(The above message only shows up when I change the logging level on the router using the "logging trap" command).

If the notification message about the change in log level is making it through to the syslog server then why aren't the other bazillion log messages there that should be since the log level is set to "debugging"?

 

by: mohawk1Posted on 2006-08-09 at 01:51:59ID: 17277348

Agreed.  The router should be sending everything.  The only command that is missing is:

 logging source-interface <your interface>

Other than that, could it be the configuration on Kiwisyslog??  I've only got v7.2.35 here so it may be quite different.

 

by: dealvisPosted on 2006-08-09 at 06:39:19ID: 17278766

My understanding is the logging source-interface is optional.
I enabled syslog on our Cisco switch and have the same problem as the router (no messages besides config change notifications).
I am going to contact KIWI support - be back later.
