Hi Friends,
I need your help regarding syslogs. We noticed that syslogs are not reflecting interfaces down or Admin shut events though logging seems to be properly configured. For example...below is the config on the router
logging buffered 10000 debugging
logging facility local1
logging source-interface Loopback10
logging xxxxx
On one of the interfaces Fa9/47, if i do a unshut and shut again, i only get the below logs on the router
May 7 17:53:35.222 Singapo: %SYS-5-CONFIG_I: Configured from console by xxxxx onvty0 (xxxx.xxxx.xxxx.xxxx)
However it does not reflect the port went down and came up. The device we are using is cisco CISCO7609.
If anyone of you have come across this, please share your suggestions. Thanks!
Best Regards,
Manoj

Hi Sam,
We added the below command after which we started receiving the logs in the router buffer.
"Logging event line-status default"
Thanks for your suggestion for snmp.

Hi Manoj,
We have 4 Cisco 4507 siwtches and when we use a show logging command there are no logs displayed for port flaps or port downs. Will this command in Cisco 4507 switches help us to display the port flap or down status? Kindly assist.

and if u don't have CCO login, see below.
logging event
To enable notification of interface, subinterface, and Frame Relay data link connection identifier (DLCI) data link status changes, use the logging event command in interface configuration mode. To disable notification, use the no form of this command.
logging event {dlci-status-change | link-status | subif-link-status [ignore-bulk]}
no logging event {dlci-status-change | link-status | subif-link-status [ignore-bulk]}
Pls rate helful posts

You are looking in global config and not finding the command. But it is not a global config command. It is an interface command. Go into interface config mode for one of your interfaces and look there. I believe that you will find the command in your interface config mode. And I believe that it will work for you to generate syslog messages when the interface goes up or goes down.

Hi
TST-POP1-NPE01(config)#logging event link-status default
TST-POP1-NPE01#sh run | inc loggi
logging snmp-authfail
logging buffered 100000 informational
no logging console
logging event link-status default <==============
above is just been tested on 7609 and it is global mode. But perhaps as Rick stated, 4507 would only take this at interface level.

Setting it as a default in global config is a nice capability. I had been aware of the logging event link-status as an interface command, and the documentation cited in a previous post identifies it as an interface command. But it looks like sometimes there is a global opportunity. I am not clear whether it is a platform variable or just a version dependent variable. Thanks for making me aware of the global possibility.

It's a pleasure to be able to repay a very microscopic amount back to the seniors who are making this forum what it is: One of the best learning tools and knowledge sharing places!
