%IP-4-DUPADDR: not showed on the gestion platform

HI all,

The thing is... our gestion platform (which receiveds the SNMP traps) don´t shows dupplicated ip addresses in the network, I mean... ie. we have a 6500 box and we can see the following line in the log: May 30 20:03:35: %IP-4-DUPADDR: Duplicate address on Vlan3003, sourced by 0015.2bb4.fa45

I understand this box has detected a device in the network with an ip which is already configured on itself, but we don´t know the way to tell the 6500 box about sending a trap to the gestion platform...

Has anyone any idea about it?

Thanks in advance.



Re: %IP-4-DUPADDR: not showed on the gestion platform

Hi Enrique,

do you have logging to a syslog server enabled?

For IOS: logging trap

and for CATOS: set logging server

If a IOS "logging trap errors" is set the warnings the the Dup_IP are not sent to the syslog server.

Only messages from Level 3 down to 0 are sent (emergencies, alerts, critical and errors)

You will find a list of levels here:

(Note: This is for another switch, but the levels are accurate)

If you want the level 4 messages sent to a syslog server you have to issue the command

IOS: logging trap warnings

CATOS: set logging server 4

And be sure logging is enabled.

Hope that helps

Best regards,
