Configuring ATM Logical Ports on Frame-based Modules
Using VP Shaping
Using VP Shaping
The VP Shaping feature provides a method of enabling Lucent switch traffic sent to a
customer network to comply with the customer’s purchased traffic contract. By using
VP Shaping, all circuits assigned to the shaper are set to the configured SCR, peak cell
rate (PCR), and MBS rates. The 1-port ATM CS DS3/E3 and 1-port ATM IWU
OC-3c/STM-1 support VP Shaping.
For ATM Direct and OPTimum Cell Trunk logical ports, you can only configure
shaper attributes when VP shaping is selected. Once you select Shaping Type = VP,
the pull-down list is enabled. For ATM OPTimum Frame Trunk logical ports, you can
select both VP and VC shaping attributes from the pull-down list.
Keep in mind that you must first configure the 1-port ATM CS DS3/E3 or 1-port ATM
IWU OC-3c/STM-1 physical port shaper attributes before you can specify these
attributes for the logical port. For information about configuring VP shaping on the
1-port ATM CS DS3/E3 or 1-port ATM IWU OC-3c/STM-1 physical ports, see the
Switch Module Configuration Guide
for CBX 3500, CBX 500, GX 550, and B-STDX 9000.
