Parameters
channel-id
: Specifies an S-channel ID (SCID) in the range of 2 to 167.
0
is the reserved SCID, and
1
is the default SCID.
svlan-id
: Specifies an S-VLAN ID (SVID) in the range of 2 to 4094.
1
is the SVID for the default
S-channel. If you do not specify this argument, the system automatically assigns the minimum SVID
that is not used by other S-channels.
Usage guidelines
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.
•
An S-channel is automatically created through CDCP, and the command line corresponding to
the action is added to the configuration file on the bridge. You can also manually create an
S-channel by using this command. If an (SCID, SVID) pair for an S-channel is created both
automatically and manually, the automatically created S-channel 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, and an S-channel interface or S-channel aggregate interface that is
automatically created through CDCP operates in trunk mode.
•
Create an S-channel on an interface with EVB enabled. Otherwise, an error message appears.
•
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.
