Nexus 5548 with FEX sync peer not rechable;ping ok;CFS peer not showing

Hi,

We have two Nexus 5548 switches along with a coupe of dual homed FEXes. All vlan, portchannel, interface configurations were done in 'conf sync' mode.

We continued like this and faced no problems. However recently i found out that after a change, i tried to verify and commit, however there is an error saying that the peer is not reachable. But i am able to ping both the Nexus switches from each others console via the appropiate vrfs. I noticed that on switch 1 i am able to see the cfs peers, but on switch 2 on giving the command following is the output:-

5548_02# show cfs peers

CFS Discovery is in Progress ..Please wait

Could not get response. The network topology may be under going change.

Please try after about 30 seconds

5548_02#

{{ Above output takes some time to display}}

I am not able to find much information about this. I disabled CFSoIP and re enabled it. Still same result. I am actually stuck here. The other things to do would be delete the switch profile and add back again or may be reload the switch.

Any help would be appreciated.

The NX OS is:-

BIOS:      version 3.6.0

loader:    version N/A

kickstart: version 5.2(1)N1(2a)

system:    version 5.2(1)N1(2a)

power-seq: Module 1: version v1.0

Module 3: version v2.0

On switch 1 peers are showing up as normal:-

5548_01# sh cfs peer
