Deployment Guide

Additionally, ARP entries resulting from station movements from VLT to non-VLT ports or to dierent non-VLT ports are learned on the
non-VLT port and synced with the peer node. The peer node is updated to use the new non-VLT port.
NOTE: ARP entries learned on non-VLT, non-spanned VLANs are not synced with VLT peers.
Verifying a VLT Conguration
To monitor the operation or verify the conguration of a VLT domain, use any of the following show commands on the primary and
secondary VLT switches.
• Display information on backup link operation.
EXEC mode
show vlt backup-link
• Display general status information about VLT domains currently congured on the switch.
EXEC mode
show vlt brief
• Display detailed information about the VLT-domain conguration, including local and peer port-channel IDs, local VLT switch status, and
number of active VLANs on each port channel.
EXEC mode
show vlt detail
• Display the VLT peer status, role of the local VLT switch, VLT system MAC address and system priority, and the MAC address and
priority of the locally-attached VLT device.
EXEC mode
show vlt role
• Display the current conguration of all VLT domains or a specied group on the switch.
EXEC mode
show running-config vlt
• Display statistics on VLT operation.
EXEC mode
show vlt statistics
• Display the current status of a port or port-channel interface used in the VLT domain.
EXEC mode
show interfaces interface
• interface: specify one of the following interface types:
• Fast Ethernet: enter fastethernet slot/port.
• 1-Gigabit Ethernet: enter gigabitethernet slot/port.
• 10-Gigabit Ethernet: enter tengigabitethernet slot/port.
• Port channel: enter port-channel {1-128}.
