13.7 Virtual Channels
Defining virtual channels (also called Permanent Virtual Circuits or PVCs) allows
you to set priorities for different services or subscribers. You can define up to eight
channels on each DSL port and use them for different services or levels of service.
You set the PVID that is assigned to untagged frames received on each channel.
You also set an IEEE 802.1p priority for each of the PVIDs. In this way you can
assign different priorities to different channels (and consequently the services that
get carried on them or the subscribers that use them).
For example, you want to give high priority to voice service on one of the DSL
ports.
Use the Edit Static VLAN screen to configure a static VLAN on the SAM1316-22
for voice on the port.
Use the DSL Edit Port Channel Setup screen to:
• Configure a channel on the port for voice service.
• Set the channel to use the PVID of the static VLAN you configured.
• Assign the channel a high priority.
13.7.1 Super Channel
The SAM1316-22 forwards frames belonging to VLAN groups that are not assigned
to specific channels to the super channel. Enable the super channel option to allow
a channel forward frames belonging to multiple VLAN groups (that are not
assigned to other channels). The super channel functions in the same way as the
channel in a single channel environment. One port can have only one super
channel.
Apply Click Apply to save your changes to the SAM1316-22’s volatile
memory. The SAM1316-22 loses these changes if it is turned off or
loses power, so use the Config Save link on the navigation panel to
save your changes to the non-volatile memory when you are done
configuring.
