Variable
Value
Priority
Type the priority to use for this port in the Spanning Tree Protocol.
If the path cost for all ports on a switch is the same, the port with
the highest priority (lowest value) is configured as an active link in
the Spanning Tree Protocol. This makes a port with higher priority
less likely to be blocked if the Spanning Tree Protocol detects
network loops. Where more than one port is assigned the highest
priority, the port with lowest numeric identifier is enabled. (Default:
128. Range: 0 to 240, in increments of 16.)
Admin Path Cost
Type the value to establish the best path between devices. Assign
lower values to ports attached to faster media, and assign higher
values to ports with slower media. Path cost takes precedence
over port priority. When the Path Cost Method is set to short, the
maximum path cost is 65 535.
Ranges:
•
Ethernet—200 000 to 20 000 000
•
Fast Ethernet—20 000 to 2 000 000
•
Gigabit Ethernet—2 000 to 200 000
Default values:
•
Ethernet—Half duplex: 2 000 000. Full duplex: 1 000 000.
Trunk: 500 000
•
Fast Ethernet—Half duplex: 200 000. Full duplex: 100 000.
Trunk: 50 000
•
Gigabit Ethernet—Full duplex: 10 000. Trunk: 5 000
Admin Link Type
Select the link type attached to this interface as follows:
•
Point-to-Point—To connect to exactly one other bridge.
•
Shared—To connect to two or more bridges.
•
Auto—To configure the switch to automatically determine the
link type.
(Default: Auto)
Admin Edge Port
(Fast Forwarding)
If the interface is connected to an end-node device, or to a LAN
segment that is at the end of a bridged LAN, select to enable.
Because 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. (Default:
Disabled)
