Hello Team,

Along with the above ill set few more parameters:


check the status of ISL port 22 on both the switches --- >> portcfgshow 22 (save it for future reference)
decom the ISL port 22--- >> portdecom 22
disable the npiv capability of e port --→>> portcfgnpivport --disable  22
lock the port to e port ---→>> portcfgeport 22  2
