Figure 3-28. ATM Service Details Screen
The Configuration table on the ATM Service Details screen is used to set the
following configuration parameters:
NOTICE:
To change an ATM Service configuration, enter the desired value for each
parameter and press the Esc key.
The Status table provides the following status information on the circuits:
8300-A2-GB20-00
Max VCC (Virtual Channel Connection) – Represents the maximum number of
Virtual Channel Connections on this ATM link. By default, each VCC will
equally share the available bandwidth. This value should be kept as low as
possible to avoid wasting bandwidth. The default value is 4.
Max VPI Bits – The default Max Virtual Path Identifier Bits value is 3 for VPI
values ranging from 0 to 8.
Max VCI Bits – The default Max Virtual Channel Identifier Bits value is 6 for
VCI values ranging from 32 to 63.
Oversubscription Factor
−
interface. Used for VBR and UBR VC connection admission control to allow
either the VBR or UBR service category connections to collectively use more
bandwidth than is available to make use of the statistical multiplexing of the
connections. Values range from 1 to 10. A value of 1 indicates no
oversubscription. A value of 5 indicates 5 times oversubscription of both VBR
and UBR is permitted.
CBR connections cannot be oversubscribed Also, if CES is in use
on the interface, PCR is limited for all AAL5 connections to the
amount the line rate can support above the commitment for CES,
and the oversubscription applies only to bandwidth above the CES
commitment.
