Cabletron Systems 6H122-16 manual Switch Configuration Screen

Switch Configuration Screen

NOTE

Ports 17 through 20 represent the backplane connections that the 6H122-16 has with the 6C105 chassis. The module has a direct connection to every other slot in the chassis.

The following describe each field of the Switch Configuration screen:

Switch Address (Read-Only)

Displays the base MAC address of the switch.

Number of Ports (Read-Only)

Displays the total number of switched ports on the module.

Type of STA (Selectable)

Allows the user to set the method that switches use to decide which switch is the controlling (Root) switch when two or more switches exist in parallel (Spanning Tree Algorithm [STA]). Valid entries include IEEE, DEC, and NONE. To set the STA, refer to Section 5.18.1.

Age Time (Modifiable)

Allows the user to set the amount of time (in seconds) the 6H122-16 will keep an address in its switch table before discarding it. The module will discard an address from its switch table if it does not receive a valid frame from the applicable address in the amount of time specified in the Age Time field. To change the Age Time field from the default value of 300 seconds, refer to Section 5.18.2.

Port # (Read-Only)

Lists each switch port on the module. If the number of ports is greater than eight, then the additional ports are listed on subsequent screens.

MAC Address (Read-Only)

Displays the hardware address assigned to each listed port.

State (Read-Only)

Disabled: Management disabled this interface. No traffic is received or forwarded while the interface is disabled.

Listening: The switch is not adding information to the Transparent Database. The switch is monitoring BPDU traffic while preparing to move from the learning to the forwarding state.
