I have Cisco CISCO7606-S (R7000) with 48 SFM-capable 48 port 10/100/1000mb
RJ45 moduleNow , I have 5 ports connected to my WiMAX ASN gateway via two vlans
one to the access side and the other one connected to the core sideThe issue am
facing now is some of the ports are into errdisable state by itself
Module diagnostics output 3 Pass
Group Port-channel Protocol

The configuration for the physical port is identical for all ports , no log
messages give a clue that there is a problemNow , if i enabled those interfaces
again , I lose the device until I restart the module again
No spanning-tree issues were noticed , I have checked everything !
What could cause this?
Thanks
