104 Chapter 9 SHDSL Port Commands
The following example creates a virtual channel profile named gold that uses LLC
encapsulation and AAL 5. It uses constant bit rate and has the maximum rate (peak cell rate)
set to 300,000 cells per second. The acceptable tolerance of the difference between a cell’s
transfer delay and the expected transfer delay (CDVT) is set to 5 cells.
ras> lcman port vcprofile set gold llc 5 cbr 300000 5
The following example creates a virtual channel profile named silver that uses VC
encapsulation and AAL 5. It uses variable bit rate and has the maximum rate (peak cell rate)
set to 250,000 cells per second. The acceptable tolerance of the difference between a cell’s
transfer delay and the expected transfer delay (CDVT) is set to 5 cells. The average cell rate
that can be transmitted (SCR) is set to 100,000 cells per second. The maximum number of
cells that the port is guaranteed to handle without any discards (BT) is set to 200.
ras> lcman port vcprofile set silver vc 5 vbr 250000 5 100000 200
The following example creates a virtual channel profile named economy that uses LLC
encapsulation and AAL 5. It uses unspecified bit rate and has the maximum rate (peak cell
rate) set to 50,000 cells per second. The acceptable tolerance of the difference between a cell’s
transfer delay and the expected transfer delay (CDVT) is set to 100 cells.
ras> lcman port vcprofile set gold llc 5 cbr 50000 100
9.4.8 PVC Set Command
Syntax:
lcman port pvc set <slot-port-vpi/vci> <super|vid=<vid>>
[llc|vc|vcprofile=<vcprofile>] [priority=<pri>]
where
This command allows the configuration of a PVC (permanent virtual circuit) for one or a
range of DSL ports. Two examples are shown next.
<slot-port-vpi/
vci>
= The slot and port(s) and VPI/VCI of the PVC.
<super|vid=<vid>>
= The super channel inherits the port’s VID (PVID) and priority.
You must assign a VID (1 to 4094) and priority to normal
channels. Each PVC must have a unique VID since the system
forwards traffic back to the subscribers based on the VLAN ID.
[llc|vc|vcprofil
e=<vcprofile>]
= Define the multiplexing mode or assign a virtual channel profile
to the PVC.
<priority>
= Set an IEEE 802.1p default priority (0 to 7) to add to incoming
frames without a (IEEE 802.1p) priority tag.
