You can enable Syslog logging using "logging " and make sure to have the command "logging event link-status" under the interfaces.

thanks Mohammed,

if you can tel me what difference between:

- snmp trap link-status


- logging event link-status

mohammedmahmoud Mon, 09/03/2007 - 06:09


snmp trap link-status > sends snmp trap to the NMS for interface status.

logging event link-status > sends logging to a syslog server for interface status.

if you have no syslog server, you can download a free one :

but if you use subinterfaces with frame relay, may be you will not receive a log msg when only one lgical interface (and not the physical) comes down.

mohammed, did you face this problem before? i think in this case we must use SNMP traps.

Hi Oussama,

For subinterfaces you must make sure that the command "logging event subif-link-status" is under the main/physical interface.
