Hello,
Anyone experience an issue if you issue a clear ip nat translation vrf <VRF_NAME> * it causes the router to reload?

Hi,
Do you have voice deployment ?????
If yes then......
{
http://www.cisco.com/en/US/docs/ios/12_4t/release/notes/124TCAVS.html
In voice deployments when you isssue a clear ip nat trans * command or a clear ip nat trans forced command and have dynamic NAT, you will wipe out the pin-hole/association and must wait for the next registration cycle from the inside device to re-estabilish this. Cisco recommends that you do not use these clear commands in a voice deployment.
Symptoms: A device that is configured with NAT crashes. SIP appears to be translated trough NAT. However, some cases report that the crash still occurs after redirecting SIP traffic elsewhere.
Conditions: The crash is triggered when the clear ip nat translation *, clear ip nat translation forced, or clear crypto ipsec client ezvpn command is entered.
Workaround: There is no workaround.
}
Regards
