show vlt mac-inconsistency

Displays inconsistencies in dynamic MAC addresses learned between VLT peers across spanned-VLANs.

Syntax

show vlt mac-inconsistency vlan

Parameters

None

Default

Not configured

Command Mode

EXEC

Usage Information

Use this command to check for a mismatch of MAC address table entries between VLT peers. Use this command only when you observe network convergence issues. To verify VLT configuration mismatch issues on peer switches, use the show vlt domain-name mismatch command.

Use this command if there are traffic convergence issues.

This show command displays all the sticky mac inconsistencies along with other mac inconsistencies in all VLANs.
