LevelOne GSW-2692 manual Spanning-tree protocol-migration, Auto

4 Command Line Interface

Default Setting

auto

Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

•Specify a point-to-point link if the interface can only be connected to exactly one other bridge, or a shared link if it can be connected to two or more bridges.

•When automatic detection is selected, the switch derives the link type from the duplex mode. A full-duplex interface is considered a point-to-point link, while a half-duplex interface is assumed to be on a shared link.

•RSTP only works on point-to-point links between two bridges. If you designate a port as a shared link, RSTP is forbidden.

Example

Console(config)#interface ethernet 1/5

Console(config-if)#spanning-tree link-type point-to-point

spanning-tree protocol-migration

This command re-checks the appropriate BPDU format to send on the selected interface.

Syntax

spanning-tree protocol-migration interface

interface

•ethernet unit/port

-unit - Stack unit. (Range: 1-8)

-port - Port number. (Range: 1-26)

•port-channel channel-id(Range: 1-6)

Command Mode

Privileged Exec

Command Usage

If at any time the switch detects STP BPDUs, including Configuration or Topology Change Notification BPDUs, it will automatically set the selected interface to forced STP-compatible mode. However, you can also use the spanning-treeprotocol-migrationcommand at any time to manually re-check the appropriate BPDU format to send on the selected interfaces (i.e., RSTP or STP-compatible).
