26.3PVC Channels
Channels (also called Permanent Virtual Circuits or PVCs) let you 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). Use the following commands to define channels.
26.3.1Set Channel Command
Syntax:
192.168.1.1 adsl> set ch <port> <vpi> <vci> <pvid> <priority> <vcp name>
or:
192.168.1.1 adsl> set ch <port> <vpi> <vci> super <vcp name>
where |
|
|
<port> | = | A port number (1 to 8) or (*) means all 8 ports. |
<vpi> | = | The VPI setting (0 to 255). |
<vci> | = | The VCI setting (32 to 65535 if vpi = 0) or (1 to 65535 if the vpi does not = 0). |
<pvid> | = | The default VID (0 to 4094). Each PVC must have a unique VID (since the network |
|
| module forwards traffic back to the subscribers based on the VLAN ID). |
<priority> | = | The IEEE 802.1p default priority (0 to 7). |
<vcp name> | = | A virtual channel profile’s name. |
super | = | Sets this channel as the super channel for this port. |
The set ch command creates a new PVC channel or modifies an existing one.
The following example creates a PVC channel for port 8 that uses VPI 0, VCI 33, PVID 6 IEEE 802.1p default priority of 3 and the gold virtual channel profile.
192.168.1.1 adsl> set ch 8 0 33 6 3 gold
26.3.2Delete Channel Command
Syntax:
192.168.1.1 adsl> delete ch <port> <vpi> <vci>
where |
|
|
<port> = | A port number (1 to 8) or (*) means all 8 ports. | |
<vpi> | = | The VPI setting (0 to 255). |
<vci> | = | The VCI setting (32 to 65535 if vpi = 0) or (1 to 65535 if the vpi does not = 0). |
