Menu Structure

The commands that you can use depend on the system that you have, your level of access, and the types of modules and other hardware options that are configured for your system. The following diagram shows the complete list of commands for all systems. See the checklist at the beginning of each command description in this chapter for whether your system supports the command.

bridge trunk summary

Displays summary information about configured trunks on your system. In a summary report, the system displays the trunk name and index number, the ports defined in that trunk, whether Trunk Control Message Protocol (TCMP) is enabled or disabled, and whether the port link is up or down.

Name

Name assigned to the trunk

Node trunk id

TCMP identifier assigned to the trunk

Node trunk id list

Node trunk identifications that each port has detected on the trunk

Ports

Ports in the trunk. The second half of the display lists each individual port in each trunk.

Present

Number of ports that participate in the trunk

rxBadType

Number of TCMP messages received that contain a bad TCMP Type field

rxBadVersion

Number of TCMP messages received that contain a bad TCMP version number

rxFrames

Number of TCMP messages received on each port

rxHellos

Number of TCMP helloMessages received on each port

rxOverflow

Number of times that TCMP has detected a TCMP trunk configuration that exceeds the eight-node maximum

rxSameTrunkId

Number of times that TCMP has received a helloMessage that contains the TCMP agent's own Node trunk id (an illegal configuration)

Selected node trunk id list

Node trunk ids that are selected for use on the trunk

State

Whether the trunk is up or down

TCMP

Whether TCMP is enabled or disabled for the trunk

Tcmpstate

TCMP state for each port in the trunk:

Trunk state

State (up or down) of each port link in the trunk

txFrames

Number of TCMP messages transmitted on each port

txHellos

Number of TCMP helloMessages transmitted on each port

Type

The network type assigned to the ports in the trunk (for example, Fast_Ethernet or Gigabit_Ethernet)

bridge trunk define

Defines one or more trunks on the system. When you define a trunk, you specify ports and characteristics for the trunk.

Possible Values

[Default]

Mac type
(if you have more than one)

Media type for the trunk (for example, Fast Ethernet or Gigabit Ethernet)

-

Ports

Number of the bridge ports that you want to be part of the trunk

-

Ports (continued)

Mode

Operating mode for the trunk

-

Flow control (Gigabit Ethernet only)

Flow control setting for a Gigabit Ethernet trunk

off

Trunk name

Name of the trunk. Use quotation marks around any character string that has embedded spaces

-

TCMP

Trunk Control Message Protocol (TCMP). Detects and handles physical configuration errors in point-to-point trunks

enabled

Procedure

You can define all trunks in one bridge trunk define operation and then reboot. At the end of each trunk definition, the system prompts you to define another trunk.

1 .   If you have more than one media type on your system, select the media type (for example, Fast Ethernet or Gigabit Ethernet).

2 .   Select the ports that you want to be part of the trunk.

To get information about the selectable ports, enter ?

3 .   Select the correct operating mode for 10/100 Ethernet ports.

If you are configuring a Fast Ethernet trunk, select the Fast Ethernet port mode (100half, 100full).

4 .   For a Gigabit Ethernet trunk only, select the Gigabit Ethernet flow control setting (on, off, rxOn, or txOn).

5 .   Enter the trunk name, or to get information about specifying the trunk name, enter ?

6 .   Specify whether TCMP is enabled or disabled.

The system indicates that the trunk definition is complete and allows you to define additional trunks until you reach the trunk limit (4).

7 .   At the system prompt, to define another trunk enter y (yes) or to end the trunk sequence, enter n (no).

You must then reboot to enable the trunks to take effect.

Bridge Trunk Define Example (9000)

The example shows a define operation that creates two trunks.

bridge trunk modify

Changes a trunk in either of two ways:

Current value

Trunk name

Name of the trunk. Use quotation marks around any character string that has embedded spaces.

Current trunk name

TCMP

Trunk Control Message Protocol (TCMP). Performs the following functions:

enabled (factory default), or current TCMP state

Procedure

To modify trunk information for a bridge, follow these steps:

1 .   Enter the trunk index number (for example, 1), or to display the selectable trunks, specify ?

The system shows the media type for the trunk (for example, Fast Ethernet, Gigabit Ethernet, or FDDI).

2 .   At the prompt, select the ports that you want to be part of the trunk, or to display a port summary, specify ?

The maximum number of ports per trunk is 8 (for CoreBuilder 3500 and CoreBuilder 9000 Layer 3 modules).

3 .   To change the 10/100 operating mode, select the new operating mode (for example, 100half, 100full), or to display information about the selectable values, specify ?

For Fast Ethernet, you can choose 100 Mbps, running in half-duplex or full-duplex mode. All ports in the trunk are set to the specified operating mode.

4 .   To change the flow control setting for a Gigabit Ethernet trunk only, select on, off, rxOn, or txOn.

5 .   To change the name of the trunk, enter the new name, or to view information on how to specify a trunk name, specify ?

The name can have up to 32 characters. Use quotation marks around any character string that has embedded spaces.

6 .   To change the TCMP state, specify enabled or disabled. The system default is enabled.

If you modified the port information, the system displays a message to inform you that the port configuration will change and then displays a reboot prompt.

7 .   At the system prompt, to reboot the system, enter y (yes) and implement the new trunk information, or to return to the previous menu, enter n (no).

Entering n (no) cancels the trunk changes. The system reports that it is unable to continue with the trunk configuration.
