Configuring an S-channel
Creating an S-channel
An S-channel is automatically created by CDCP, and the system automatically saves the configuration in
the configuration file on the bridge. You can also manually create an S-channel by performing this task.
If an (SCID, SVID) pair for an S-channel is created both automatically and manually, the one
automatically created takes precedence.
After an S-channel is created, an S-channel interface or S-channel aggregate interface is generated.
Removing an S-channel also removes the S-channel interface or S-channel aggregate interface. A
manually created S-channel interface or S-channel aggregate interface operates in access mode. An
S-channel interface or S-channel aggregate interface that is automatically created through CDCP
operates in trunk mode.
An S-channel interface is associated with the S-channel that is created on a Layer 2 Ethernet interface. An
S-channel aggregate interface is associated with the S-channel that is created on a Layer 2 aggregate
interface.
When you create an S-channel, follow these guidelines:
•
Create an S-channel on an interface with EVB enabled. Otherwise, an error message appears.
•
A default S-channel is created on an interface after EVB is enabled on the interface. Both SCID and
SVID are 1.
•
When you manually create an S-channel, do not use the SCID or SVID being used by any other
S-channel. Otherwise, an error message appears.
•
To manually create or remove S-channel, disable CDCP that automatically performs these
operations.

By default, only an automatically
created default S-channel (with
both SCID and SVID as 1) exists on
an interface with EVB enabled.
