Configuring Fabric Ports

Context

When the parent is connected to a level-1 AS through a fabric port, the parent-side fabric port needs to be manually configured, while the level-1 AS-side fabric port is auto-negotiated between the level-1 AS and parent.

When a level-1 AS needs to be connected to a level-2 AS, the fabric port that connects the level-1 AS to the level-2 AS needs to be manually configured, while the fabric port that connects the level-2 AS to the level-1 AS is negotiated. After service configurations have been delivered from the parent, the port that connects the level-1 AS to the level-2 AS becomes Up and then the level-2 AS can go online.

Procedure

Configure a fabric port that connects the parent to a level-1 AS.
1. Run system-view
  The system view is displayed.
2. Run uni-mng
  The uni-mng view is displayed.
3. Run interface fabric-port port-id
  A fabric port is created and the fabric port view is displayed.
4. Run port member-group interface eth-trunk trunk-id
  The fabric port is bound to an Eth-Trunk.
  
  A fabric port can be bound to only the Eth-Trunk that has not been created. When a fabric port is bound to an Eth-Trunk, the system creates the Eth-Trunk.
5. (Optional) Run description description
  The description of a fabric port is configured.
  
  By default, a fabric port does not have a description.
  
  To facilitate fabric port management and identification, you can configure descriptions for fabric ports. For example, you can describe the name of an AS that connects to a fabric port.
6. Run quit
  Exit from the fabric port view.
7. Run quit
  Exit from the uni-mng view.
8. Run interface interface-type interface-number
  The interface view is displayed.
9. Run eth-trunk trunk-id
  The current interface is added to the Eth-Trunk.
  - You can perform steps 8 and 9 multiple times to add multiple interfaces to an Eth-Trunk.
  - After an Eth-Trunk is bound to a fabric port, the configuration of this Eth-Trunk is automatically generated based on the services configured on the AS to which this Eth-Trunk is connected, and some commands can also be configured on this Eth-Trunk based on the scenario. Currently, the authentication open ucl-policy enable command and the mac-address multiport command can be configured.
  - Before removing an Up member port from a fabric port, run the shutdown command in the interface view to shut down the member port.
  - When a port joins a downlink fabric port of the parent, the port enters the blocking state. When the port negotiates with the peer port successfully, the port is unblocked.
Configure a fabric port that connects a level-1 AS to a level-2 AS. This configuration is required only when a level-1 AS is connected to level-2 ASs and has gone online.
1. Run system-view
  The system view is displayed.
2. Run uni-mng
  The uni-mng view is displayed.
3. Run as name as-name
  The AS view is displayed.
4. Run down-direction fabric-port port-id member-group interface eth-trunk trunk-id
  The fabric port that connects a level-1 AS to a level-2 AS is configured.
  
  trunk-id specifies the Eth-Trunk to which the fabric port is bound.
5. Run port eth-trunk trunk-id trunkmember interface interface-type interface-number1 [ to interface-number2 ]
  Member ports are added to the Eth-Trunk to which the fabric port is bound.
  - Before removing an Up member port from a fabric port, you must run the shutdown interface interface-type interface-number command in the AS view to shut down the member port.
  - When a port joins a downlink fabric port of a level-1 AS, the port enters the blocking state. When the port negotiates with the peer port successfully, the port is unblocked.

Verifying the Configuration

Run the display uni-mng interface fabric-port configuration [ parent | as name as-name ] command to check the fabric port configuration.
Run the display uni-mng interface fabric-port [ port-id ] state command to check the fabric port status.
