RSTP configuration

RSTP mode is supported on VLT ports. Before you configure VLT on peer switches, configure RSTP in the network. RSTP prevents loops during the VLT startup phase.

  • Enable RSTP on each peer node in CONFIGURATION mode.
    spanning-tree mode rstp

Configure RSTP — peer 1

OS10(config)# spanning-tree mode rstp
