Which two operational attributes can be checked for EtherChannel ports that are in err-disabled state?
A. Port mode
B. Port cost
C. Duplex
D. DTP
E. VLAN
Correct Answer: AE
Explanation/Reference:
Compatibility Requirements When you add an interface to a channel group, Cisco NX-OS checks certain interface attributes to ensure that the interface is compatible with the channel group. Cisco NX-OS also checks a number of operational attributes for an interface before allowing that interface to participate in the port-channel aggregation.The compatibility check includes the following operational attributes:
■ Port mode
■ Access VLAN
■ Trunk native VLAN
■ Allowed VLAN list
■ Speed
■ 802.3x flow control setting
■ MTUThe Cisco Nexus 5000 Series switch only supports system level MTU. This attribute cannot be changed on an individual port basis.
■ Broadcast/Unicast/Multicast Storm Control setting
■ Priority-Flow-Control
■ Untagged CoS Use the show port-channel compatibilityparameters command to see the full list of compatibility checks that Cisco NX-OS uses.
