Table 3-3. Add Logical Port: Administrative Tab Fields
Field Action/Description
Bandwidth (Kbps):
Allocated
Available
Enter the amount of bandwidth allocated for this logical port. The
default (which also shows in the Available field) is the amount of
bandwidth remaining from the physical clock rate less any logical
ports already configured.
• If you are defining more than one ATM UNI or NNI logical port
type on this port (Virtual UNI/NNI), be sure to adjust the
bandwidth value to accommodate these virtual ports.
• If you are defining an OPTimum cell trunk on this port,
configure this UNI logical port with a minimal amount of
bandwidth.
For specific guidelines on configuring bandwidth with the various
physical port types, see page 2-18.
VP Shaping Enables or disables VP shaping, which provides a method for traffic
sent over a Lucent switch through another network to comply with
the purchased traffic contract in that other network. The ATM FCP
functions shape individual cell trunk or virtual UNI/NNI logical
port traffic at the configured VP shaping rate.
CBX 3500 and CBX 500 – Supported on virtual UNI and OPTimum
Trunk logical ports on I/O modules with FCP enabled. For more
information, see “About VP Shaping on the CBX 500 and CBX
3500” on page 2-20. For configuration instructions, see
“ILMI/OAM Attributes” on page 3-34.
GX 550 – Supported on virtual UNI, Virtual NNI, and OPTimum
Trunk logical ports on BIO2 modules. For more information, see
“About VP Shaping on the GX 550” on page 2-21.
Note: Modifying the value for this attribute does not admin down
the logical port.
