IP SNAT Conn Proc

Hi,

I saw the IP SNAT Conn Proc is holding the memory too much.

Is there any bug for ip sant processor?

My IOS version is C2800NM-ADVSECURITYK9-M), Version 12.4(5). 2821 is the router.

Is the bug CSCsd66869 problem for my ip snat.

But when checked with show ip nat trans, there is no nat entries at all. All nat entries has expired on both routers.

What can be the problem? Can some body help on this please.

Re: IP SNAT Conn Proc

Hi,

use this command to view snat entries

show ip snat distributed

Try to clear SNAT entries from the translation table before they time out.

using the command

clear ip snat sessions *

and also this command

clear ip snat translation distributed *

HTH

Thanks,
