Getting Physical port failure error on Nexus 7000 switch

[nayanpanchal]

I've Nexus 7010 switch installed in my DC. I've conncected Cisco router to one of the Ports. On the same port I'm getting following error message and hence, unable to form EIGRP neighborship.

DR-CORE-SW-S01-NEXUS7K %MODULE-2-MOD_SOMEPORTS_FAILED:

Module 1 (serial: JAF*******NGK) reported failure on ports 1/2-1/2 (Ethernet) due

to R2D2 : Speed patch failed - no frames transmitted in device 143 (error 0xc8f0

1273)

Please suggest what is the solution for this.
