Virtual Channel Management
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
12.2.2
Delete Virtual Channel Profile Command
Syntax:
ras>
lcman port
vcprofile delete <vcprofile>
where
<vcprofile> =
The name of the virtual channel profile (up to 31 ASCII characters). You cannot
delete the DEFVAL or DEFVAL_VC profiles.
You cannot delete a virtual channel profile that is assigned to any of the DSL ports on any of the line cards in the
Integrated Ethernet Switch. Assign a different profile to any DSL ports that are using the profile that you want to
delete, and then you can delete the profile.
The following example deletes the silver virtual channel profile.
lcman port
vcprofile delete silver
12.2.3
Show Virtual Channel Profile Command
Syntax:
ras>
lcman port
vcprofile show [<vcprof_name>]
where
<vcprof_name> =
The name of the virtual channel profile (up to 31 ASCII characters).
Displays a list of configured virtual channel profiles. Specify a virtual channel profile to display its settings.
