ATM OPTimum Cell Trunks
To implement the ATM OPTimum cell trunk, first configure a UNI DTE feeder logical
port on the same physical port. (1-port ATM CS DS3/E3 and 1-port ATM IWU
OC-3c/STM-1 ports can also use a UNI DCE port for this purpose.)
To configure an ATM OPTimum cell trunk, perform the following steps:
Configuring ATM Direct or OPTimum Cell Trunks
To configure an ATM direct trunk or ATM OPTimum cell trunk logical port:
1. Complete the General tab fields in the Add Logical Port dialog box as described in
“Defining ATM UNI DCE/DTE Logical Ports” on page 4-15
and
list all possible general and administrative attributes for an ATM
logical port. The attributes vary depending on the type of IOM.
2. If you are configuring an ATM DS3/E3 UNI module, select a traffic shaper ID by
clicking on Select.
displays the Select Traffic Shaper
dialog box.
Choose a value from 1 through 16 to specify the Shaper ID. This list provides both
VP and VC shaping attributes. Make sure you assign only one trunk logical port
per shaper ID. Assigning more than one trunk logical port to a given shaper ID
decreases circuit performance.
describes the fields in the
Select Traffic Shaper dialog box. For more information, see
of Valid Bits in VPI/VCI for the B-STDX 9000” on page 4-5
Step 1.
Configure the physical port you want to use for the ATM OPTimum cell trunk
(see the Switch Module Configuration Guide for CBX 3500, CBX 500, GX 550,
and B-STDX 9000).
Step 2.
Configure a UNI DTE feeder logical port (
) for the ATM OPTimum
cell trunk on this physical port. Assign this logical port a minimum amount of
bandwidth.
Step 3.
Configure the ATM OPTimum cell trunk logical port on the same physical port.
Assign the remaining bandwidth to this logical port (if there is only one ATM
OPTimum cell trunk configured on the physical port).
Step 4.
Configure the trunk (see
