Configuring Per Port Parameters - HP 3500 Series Advanced Traffic Management Manual

Configuring Per Port Parameters

Syntax: [no] spanning-tree <port-list> admin-edge-port
Enable admin-edge-port on ports connected to end nodes.
During spanning tree establishment, ports with admin-
edge-port enabled transition immediately to the
forwarding state. If a bridge or switch is detected on the
segment, the port automatically operates as non-edge, not
enabled. (Default: No - disabled)
If admin-edge-port is disabled on a port and auto-edge-port
has not been disabled, the auto-edge-port setting controls
the behavior of the port.
The no spanning-tree < port-list > admin-edge-port command
disables edge-port operation on the specified ports.
Syntax: [no] spanning-tree < port-list > auto-edge-port
Supports the automatic identification of edge ports. The
port will look for BPDUs for 3 seconds; if there are none it
begins forwarding packets. If admin-edge-port is enabled
for a port, the setting for auto-edge-port is ignored whether
set to yes or no. If admin-edge-port is set to No, and auto-
edge-port has not been disabled (set to No), then the auto-
edge-port setting controls the behavior of the port. (Default:
Yes - enabled)
The no spanning-tree < port-list > auto-edge-port command
disables auto-edge-port operation on the specified ports.
Syntax: spanning-tree < port-list > hello-time < global | 1 - 10 >
When the switch is the CIST root, this parameter specifies
the interval (in seconds) between periodic BPDU
transmissions by the designated ports. This interval also
applies to all ports in all switches downstream from each
port in the < port-list >. A setting of global indicates that the
ports in < port-list > on the CIST root are using the value set
by the global spanning-tree hello-time value (page 3-22).
When a given switch "X" is not the CIST root, the per-port
hello-time for all active ports on switch "X" is propagated
from the CIST root, and is the same as the hello-time in use
on the CIST root port in the currently active path from
switch "X" to the CIST root. (That is, when switch "X" is
not the CIST root, then the upstream CIST root's port hello-
time setting overrides the hello-time setting configured on
switch "X").
(Default Per-Port setting: Use Global.
Default Global Hello-Time: 2.)
