Current port configuration

The port option of MRST is turned on by default.

The following table describes the commands used to configure CIST Port Configuration Menu options.

Table 109 CIST Port Configuration Menu options

Command

Description

 

 

prior <0-240>

Configures the CIST port priority. The port priority helps determine which bridge port

 

becomes the designated port. In a network topology that has multiple bridge ports

 

connected to a single segment, the port with the lowest port priority becomes the

 

designated port for the segment. The range is 0 to 240, in steps of 16 (0, 16, 32...),

 

and the default is 128.

 

 

cost <1-200000000>

Configures the CIST port path cost. The port path cost is used to help determine the

 

designated port for a segment. Generally speaking, the faster the port, the lower the

 

path cost. The default is 20000 for Gigabit ports.

 

 

hello <1-10>

Configures the CIST port Hello time. The Hello time specifies how often the root

 

bridge transmits a configuration bridge protocol data unit (BPDU). Any bridge that is

 

not the root bridge uses the root bridge Hello value. The range is 1 to 10 seconds,

 

and the default is 2 seconds.

 

 

link autop2pshared

Defines the type of link connected to the port, as follows:

 

auto: Configures the port to detect the link type, and automatically match its settings.

 

p2p: Configures the port for Point-To-Point protocol.

 

shared: Configures the port to connect to a shared medium (usually a hub).

 

The default link type is auto.

 

 

edge disableenable

Enables or disables this port as an edge port. An edge port is not connected to a

 

bridge, and can begin forwarding traffic as soon as the link is up. Configure server

 

ports as edge ports (enabled). This command is disabled by default.

 

 

on

Enables CIST on the port.

 

 

off

Disables CIST on the port.

 

 

cur

Displays the current CIST port configuration.

The GbE2c supports the IEEE 802.1d Spanning Tree Protocol (STP) and Cisco proprietary PVST and PVST+ protocols. You can configure up to 127 spanning tree groups on the GbE2c (STG 128 is reserved for switch management). Spanning Tree is turned on by default.

NOTE: When RSTP is turned on, only STP group 1 can be configured.
