Field
From the pull-down menus, select both the forward and reverse circuit
priority values. 1 is high priority, 2 is medium priority, 3 is low priority,
and 4 is lowest priority. (For a B-STDX endpoint, the priority range is
from 1 – 3 only.) The forward and reverse circuit priority values do not
have to match. CBR QoS class priority is set to 1.
Note: This is applicable for VBR-RT and VBR-NRT classes only. This
field will be grayed out for CBR, UBR, and ABR classes.
Select, from the pull-down menu, one of the following TD options:
PCR CLP=0 (cells/sec) – Displays only if you selected a TD
combination that includes PCR CLP=0. If so, specify the peak cell rate
(PCR) in cells per second (CS) for high-priority traffic (that is, the
CLP=0 cell stream).
PCR CLP=0+1 (cells/sec) – Specify the PCR in CPS for the combined
high- and low-priority traffic (that is, the CLP=0+1 aggregate cell
stream).
SCR CLP=0 (cells/sec) – Displays only if you selected a TD
combination that includes SCR CLP=0. If so, specify the sustainable
cell rate (SCR) in CPS for the combined high-priority traffic (that is,
the CLP=0 cell stream).
SCR CLP=0+1 (cells/sec) – Displays only if you selected a TD
combination that includes SCR CLP=0+1. If so, specify the SCR in
CPS for the combined high- and low-priority traffic (that is, the
CLP=0+1 aggregate cell stream).
MBS CLP=0 (cells) – Displays only if you selected a TD combination
that includes MBS CLP=0. If so, specify the maximum burst size
(MBS) in CPS for the combined high-priority traffic (that is, the
CLP=0 cell stream).
MBS CLP=0+1 (cells) – Displays only if you selected a TD
combination that includes MBS CLP=0+1. If so, specify the MBS in
CPS for the combined high- and low-priority traffic (that is, the
CLP=0+1 cell stream).
MCR CLP=0 (cells/sec) – Displays only if you selected a TD
combination that includes MCR CLP=0. If so, specify the minimum
cell rate (MCR) in CPS for the combined high-priority traffic (that is,
the CLP=0 cell stream).
Although the MCR TD is only applicable to a CBX 500 with an FCP,
this attribute is offered as a selection on non-CBX endpoints. This is
because even though one or both endpoints may not be on a CBX with
FCP, the PVC might traverse a CBX 500 FCP trunk. In this case, the
provisioned attribute is used.
Note: On ATM circuit emulation (CE) endpoint(s), the PCR, SCR, and
MCR CPS values default to 118980 and cannot be changed.
