If an (SCID, SVID) pair for an S-channel is created both automatically and manually, the one automatically created takes precedence. A manually created S-channel has an access link type, and an automatically created S-channel has a trunk link type. The device checks C-VLAN tagged frames (frames taking the original VLAN tags) entering an S-channel for their C-VLAN tags. If the C-VLAN does not belong to the VLANs that the S-channel and the port where the S-channel is created permit, the device cannot transmit the frames. Therefore, you must specify the C-VLAN range for the frames that an S-channel can transmit before you assign the S-channel and the port where the S-channel is created to these C-VLANs. For more information about assigning ports to a VLAN, see Layer 2-LAN Switching Configuration Guide. Follow these guidelines when you create an S-channel: • Create an S-channel on a port with EVB enabled. Otherwise, an error is displayed. • A default S-channel with both SCID and SVID as 1 is automatically created for the port on which EVB is enabled. • When you manually create an S-channel, do not use the SCID or SVID being used by any other S-channel. Otherwise, an error is displayed. • To manually create or remove S-channel, disable CDCP to automatically perform these operations. To create an S-channel: Step 1. Enter system view. 2. Enter Ethernet interface view. Command system-view interface interface-type interface-number 3. Create an S-channel. evb s-channel channel-id service-vlan svlan-id Remarks N/A N/A By default, only the automatically created default S-channel, with both SCID and SVID as 1, exists on a port with EVB enabled. Configuring a description for an S-channel interface Step 1. Enter system view. 2. Enter S-channel interface view. 3. Configure a description for the S-channel interface. Command system-view interface s-channel interface-number:channel-id description text Remarks N/A N/A The default description information is "interface name Interface." Configuring the RR mode for an S-channel EVB TLVs exchanged through LLDP allow an EVB station and EVB bridge to negotiate the use of reflective relay. When the EVB station requests the use of RR mode and the EVB bridge supports RR mode, the bridge automatically enables RR mode for the S-channel and saves the configuration in the configuration file on the bridge. You can also manually enable RR mode for an S-channel by performing this task. 6
