Configuring CBX or GX Logical Ports
Working With ATM Logical Ports
To define the logical port for a GX 550 1-port OC-48c/STM-16c 
module:
a. Expand the BIO-C card node, then expand the Subcards class node to display 
the slots instance nodes.
b. Expand the slot node, then expand the PPorts class node and the PPort 
instance node.
c. Expand the Subports class node, then the Subport instance node.
To define the logical port for a GX 550 ES switch:
a. Expand the GX 550 switch node in the lefthand side of the Navis EMS-CBGX 
dialog box, then expand the Subcards class node to display the slot containing 
the 1-port SW Down Link module.
b. Expand the PPorts class node, then the PPort instance node.
