Consistency checks and compatibility checks are performed before a vPC is created. During a compatibility check, one vPC peer conveys configuration information to the other vPC peer to verify that vPC member ports can actually form a port channel. Which option is considered as a Type-2 misconfiguration?
A. port MTU mismatch
B. native VLAN mismatch
C. STP interface settings
D. VLAN mismatch
Correct Answer: D
Explanation/Reference:
Explanation:
If the PortChannel ports are suspended, a mismatch occurred in the PortChannel ports between the switches that are supposed to bring up the PortChannel. For example, a vPC on the Cisco Nexus 7000 Series is configured with ports that individually connect to two different PortChannels on the Cisco Nexus 5000 Series.
Alternatively, if the access-layer ports are not configured for a channel, the Cisco Nexus 7000 and 5000 Series will operate normally with spanning tree. If the ports on the Cisco Nexus 5000 Series are configured in passive channel-group mode and the Cisco Nexus 7000 Series ports are not configured for PortChannels, the Cisco Nexus 7000 and 5000 Series run spanning tree again on those ports.
