Disable CISCO-GENERAL-TRAPS "TcpConnectionClose".1.3.6.1.4.1.9.0.1

[kwengenfu]

I want to disable this trap for 3550 , but what is the command ? I try to use the following command but failed

no snmp-server enable traps

Any suggestion ?

Hi,

I think they are sent by

snmp-server host .... tty

command.

Does "no snmp-server enable traps tty" help?

[kwengenfu]

Thanks,

do not support "tty" and "x25" .

For More Info, see "Cisco IOS SNMP Traps Supported and How to Configure Them"

where do you see this traps, on LMS or NNM? If its NNM its probably esieast to set them to "dont`t log or display"

[kwengenfu]

I see those traps using Sniffer, and then I set NNM to display those(default is don't log or display).

You may ask why ?

Accourding to sniffer result, This type of trap is "Top one trap" in my company now. and it is no use for us.

Disable such trap ,decrease total trap count.

As you cannot turn this trap off alone, I would ask myself what the reason is. I can hardly imaging that it is normal behaviour that this one is the top one. Perhaps there is a management application causing these traps. Or are you opening and closing tty sessions to your 3550s such often?-then you really just have to live with it or turn it off for special sources... :-(

Dear Martin:

If you are interesting in this case you can mail to kwengenfu@ebtelco.com to get more Info.

I think this is CMS application causing such traps(I am not sure now).
