Bring up the interface. undo shutdownBy default, the S-channel interfaceor S-channel aggregate interface isup.Configuring the RR mode for an S-channelEVB TLVs exchanged through LLDP allow an EVB station and EVB bridge to negotiate the use of reflectiverelay. When the EVB station requests the use of the RR mode and the EVB bridge supports the RR mode,the bridge performs the following tasks:• Automatically enables the RR mode for the S-channel.• Saves the configuration in the configuration file on the bridge.You can also manually enable the RR mode for an S-channel by performing this task.To configure the RR mode for an S-channel:Step Command Remarks1.
