An interface on 2921 router is not coming up. When I shut/no shut the interface, I see this:
Router#sh log | i 0/2
Oct 17 08:55:06: %IP_VFR-7-FEATURE_DISABLE_IN: VFR(in) is manually disabled through CLI; VFR support for features that have internally enabled, will be made available only when VFR is enabled manually on interface GigabitEthernet0/2

Router#sh int gi0/2

Kashish,
See if "ip virtual-reassembly" on the interface resolves the issue. Then do your shut/no shut.
HTH,

I tried that as well, but it remains down, down.
interface GigabitEthernet0/2
ip address <>
no ip redirects
no ip proxy-arp
ip nat outside
ip virtual-reassembly in
shutdown
duplex auto
speed auto
end

Hi,
Have you checked for physical layer issues? I see the link itself is getting down : %LINK-3-UPDOWN
Kind Regards,
Ivan Shirshin
