Configuring the Switch



24-Port 10/100 + 4-Port Ggabt Swtch wth WebVew and Power over Ethernet

Prorty

Defines the priority used for this port in the

Spanning Tree Protocol . If the path cost for all ports on
a switch are the same, the port with the highest priority
(i .e ., lowest value) will be configured as an active link in
the Spanning Tree . This makes a port with higher priority
less likely to be blocked if the Spanning Tree Protocol is
detecting network loops . Where more than one port is
assigned the highest priority, the port with lowest numeric
identifier will be enabled .

Default: 128

Range: 0-240, in steps of 16

Port Fast

You can enable this option if an interface

is attached to a LAN segment that is at the end of a
bridged LAN or to an end node . Since end nodes cannot
cause forwarding loops, they can pass directly through
to the spanning tree forwarding state . Specifying Edge
Ports provides quicker convergence for devices such as
workstations or servers, retains the current forwarding
database to reduce the amount of frame flooding required
to rebuild address tables during reconfiguration events,
does not cause the spanning tree to initiate reconfiguration
when the interface changes state, and also overcomes
other STA-related timeout problems . However, remember
that Edge Port should only be enabled for ports connected
to an end-node device . (Default: Dsabled)

The Port Information display the current status of the
ports in the Rapid Spanning Tree .

Port

Displays the port number .

State

Shows if Rapid Spanning Tree has been enabled on

this interface .

Status

Displays current state of this port within the

Spanning Tree:

Dscardng

Port receives STA configuration messages,

but does not forward packets .

Learnng

Port has transmitted configuration messages

for an interval set by the Forward Delay parameter
without receiving contradictory information . Port
address table is cleared, and the port begins learning
addresses .

Forwardng

Port forwards packets, and continues

learning addresses .

Role

Roles are assigned according to whether the port

is part of the active topology connecting the bridge to
the root bridge (i .e ., root port), connecting a LAN through
the bridge to the root bridge (i .e ., designated port), or is
the MSTI regional root (i .e ., master port); or is an alternate
or backup port that may provide connectivity if other
bridges, bridge ports, or LANs fail or are removed . The role
is set to disabled (i .e ., disabled port) if a port has no role
within the spanning tree .

Forward Transtons

The number of times this port has

transitioned from the Learning state to the Forwarding
state .

Operatonal Edge Port

This parameter is initialized

to the setting for Administrative Edge Port in STP Port
Setting detail, but will be set to false if a BPDU is received
indicating that another bridge is attached to this port .

Operatonal Lnk Type

The operational point-to-point

status of the LAN segment attached to this interface . This
parameter is determined by manual configuration or by
auto-detection, as described for Administrative Link Type
in the STP Port Setting detail .

Click the Detal button to configure Protocol Migration
Test and Administrative Link Type . Use the check box
and drop-down menu provided to enable and select the
mode, then click Apply .
