Spantree Vlan Auto-Edge - Alcatel-Lucent 060321-10, Rev. B Cli Reference Manual

Distributed Spanning Tree Commands

spantree vlan auto-edge

Configures whether or not Spanning Tree determines the operational edge port status for a port or a link
aggregate of ports for the specified per-VLAN mode VLAN instance.
spantree vlan vlan_id {port slot/port[-port2] | linkagg linkagg_id [-linkagg_id2]} auto-edge {enable |
disable}
Syntax Definitions
vlan_id
slot/port[-port2]
linkagg_id[-linkagg_id2]
enable
disable
Defaults
By default, automatic edge port status configuration is enabled (on).
Platforms Supported
OmniSwitch 10K
Usage Guidelines
•
This command only applies to the specified VLAN instance regardless of which operating mode (flat
or per-VLAN) is active for the switch.
•
If the switch is running in the flat mode when this command is used, the specified edge port status for
the port is not active for the VLAN instance until the switch is running in the per-VLAN Spanning
Tree mode.
•
The administrative edge port status is used to determine if a port is an edge or non-edge port when
automatic edge port configuration (auto-edge) is disabled for the port. However, if auto-edge is
enabled for the port, then the administrative status is overridden.
•
Rapid transition of a designated port to forwarding can only occur if the connection type of the port is
defined as point to point or an edge port. Rapid transition of an alternate port role to a root port role is
not affected by the port connection type definition.
•
Configure ports that connect to a host (PC, workstation, server, and so on.) as edge ports to avoid
unnecessary topology changes when these ports go active. This also prevent the flushing of learned
MAC addresses on these ports if a topology change occurs as a result of another non-edge port going
active. If an edge port receives a BPDU, it operationally reverts back to a no point to point connection
type.
OmniSwitch CLI Reference Guide
An existing VLAN ID number.
The slot number and port number of the physical port. Use a hyphen to
specify a range of ports (4/1-8).
The link aggregate ID number. Use a hyphen to specify a range of IDs.
Spanning Tree automatically determines edge port status.
Spanning Tree does not automatically determine edge port status.
