Table 10-15. Add Point-to-Multipoint PVC Root: Administrative Tab
Fields
Field
Root Name Enter an alphanumeric name for the circuit root.
Circuit Type Specify whether the circuit is a virtual path connection (VPC) or
virtual channel connection (VCC, the default). If you select VPC,
the VCI field is set to zero (0) and cannot be changed.
VPI (0-15) Enter a value from 0-15 to represent the VPI for the PVC. The
maximum value you can enter is based on the valid bits in VPI
that are configured for the logical port. See
information about setting this value.
VCI (1-1023) Depending on the circuit configuration, enter a value from
(For VCCs only) 1-1023 to represent the VCI for an ATM PVC. Although you can
configure VCIs in the 1 – 31 range (with the exception of
VCI=4), the ATM Forum reserves VCIs in this range for various
purposes. You should only use a VCI in the 1 – 31 range if you
are certain that compatibility issues will not arise with any
attached non-Lucent equipment. See
about setting this value.
Enter a value between 1 - 65535 µsec to define the CDVT. The
CDV Tolerance
(1-65535) UPC uses this value to police the requested TD. The default is
600 µsec.
(microsec)
Note: If you are using the CBX 500 3-Port Channelized DS3/1
IMA IOM or the CBX 3500 3-Port Channelized DS3/1 Enhanced
IMA module, the recommended minimum CDV Tolerance value is
1000 µsec.
The recommended minimum for the 1-Port Channelized
STM-1/E1 IMA IOM or the CBX 3500 1-Port Channelized
STM-1/E1 Enhanced IMA module is 1200 µsecs.
Resource Determines whether this PVC is restricted to trunks of its own
Partitioning/ Layer2 VPN or can use public (shared) trunks during overflow
Network Overflow conditions. To configure this circuit for a specific Layer2 VPN
and customer, see
VPNs, see
Select one of the following options:
Public – (default) PVCs are routed over dedicated Layer2 VPN
trunks. However, in the event of failure, the customer's traffic is
allowed to run over common trunks (shared by a variety of
different customers).
Restricted – PVCs can only use dedicated Layer2 VPN trunks. A
customer using this mode must purchase redundancy trunks to be
used in the event of outages or other trunk failures.
