Figure 48 SHDSL Profile Delete Command Example
9.4.7 Virtual Channel Profile Set Command
Syntax:
lcman port vcprofile set <vcprofile> <llc|vc> <aal_num> <cbr|vbr|ubr>
<opt_param>
where
This command creates a virtual channel profile. After you create a virtual channel profile, you
can assign it to any of the DSL ports on any of the DSL line cards in the Integrated Ethernet
Switch.
ras> lcman port profile delete shdsl test
<vcprofile>
= The name of the virtual channel profile (up to 31 ASCII
characters). You cannot change the
DEFVAL or DEFVAL_VC
profiles.
<llc|vc>
= The type of encapsulation (llc or vc)
<aal_num>
= The ATM Adaptation Layer (AAL 5).
<cbr|vbr|ubr>
= The type of ATM traffic class:
cbr
(constant bit rate),
vbr
(variable bit rate), or
ubr
(unspecified bit rate).
<opt_param>
= These are the ATM traffic settings:
<pcr> <cdvt>
. If you use
vbr
, you must also set
<scr>
and
<bt>
. * sets the default
value.
<pcr>
= Peak Cell Rate (0 to 300000 or *), the maximum rate
(cells per second) at which the sender can send cells.
<cdvt>
= Cell Delay Variation Tolerance The accepted
tolerance of the difference between a cell’s transfer delay and
the expected transfer delay (number of cells). 0 to 255 cells or *
(means 0).
<scr>
= The Sustained Cell Rate sets the average cell rate
(long-term) that can be transmitted (cells per second). SCR
applies with the vbr traffic class.
<bt>
= Burst Tolerance this is the maximum number of cells
that the port is guaranteed to handle without any discards
(number of cells). BT applies with the vbr traffic class.
