Configuring ATM Over MPLS Trunks
Configuring Physical Ports for ATMoMPLS Trunks
Configuring Physical Ports for ATMoMPLS Trunks
You can configure ATMoMPLS trunks on any of the following modules:
• 1-port OC-12c/STM-4 Module with 128MB on CBX 500 IOM1 Module
• 1-port OC-12c/STM-4 Phy Module with 128MB on GX 550 BIO2 Module
• 4-port OC-12c/STM-4 Module on CBX 3500 Universal IOP
Before you can configure the feeder port required for an ATMoMPLS trunk, the
physical port must have:
• No logical ports configured on the physical port
• APS redundancy configured as None or Bi-directional Fast APS 1+1.
Uni-directional APS is not supported
The APS feature is available on all types of CBX and GX optical interfaces. APS
allows you to protect optical interfaces by provisioning a backup (protection) port that
automatically takes over for the primary (working) port when a physical layer fault or
module failure occurs.
To access the physical port configuration settings using Navis EMS-CBGX:
1. Expand the Cards node under the switch.
2. Expand the node for the card, expand the PPorts node, then expand the node for
the physical port.
Figure 8-6. Managing PPorts and LPorts
3. Perform one of the following:
• Select Modify from the Actions menu.
• Choose the Modify button on the toolbar.
• Right-click on the PPorts node and select Modify from the pop-up menu.
Note – For information about configuring the physical port and enabling APS, refer
to the Switch Module Configuration Guide
for CBX 3500, CBX 500, GX 550, and
B-STDX 9000
