Other Redundancy Options

Figure 8-7illustrates only a single ESP-to-BXM redundancy option. There are four ESP-to-BXM redundancy options possible:

1A single ESP with a Y-cable to redundant BXMs.

2Two ESPs (a redundant pair), each attached to a single port on a single BXM.

3Two ESPs (a redundant pair), each attached to a single port on two separate (redundant) BXMs.

4Two ESPs (a redundant pair), each attached to different ports with Y-cables on two separate (redundant) BXMs.

Y-cables are for connecting the ESP’s ATM Network Interface Card to redundant BXMs. They do not necessarily indicate that the ESP is connected in the redundant pair configuration (that is, an active and standby ESP). The Cisco WAN Service Node Extended Services Processor Installation and Operation document contains further information about ESP Y cables.

Network Management

As shown in Figure 8-5,the BPX switch can have an Ethernet LAN connection to a Cisco StrataView Plus Workstation. Cisco StrataView Plus discovers and monitors the ESP similarly to the way it does an MGX 8220 interface shelf. Cisco StrataView Plus discovers the existence of the ESP when it is added to the BPX switch with the addshelf command. After discovery, the ESP will be displayed on the Cisco StrataView Plus topology map as a shelf attached to the BPX switch.

Cisco StrataView Plus manages the BPX switch by providing:

•

•

Telnet access to the ESP Configuration Interface.

Configuration backup and restore

•Image download allows the user to select an ESP from the topology map and then select Image Download from a pull-down menu. A dialog screen displays the list of available image files and prompts the user to select a file. The selected file is sent to the ESP.

Resource Partitioning

During provisioning, resources on all UNI ports (both ATM and Frame Relay) are partitioned between SVCs and PVCs. Partitioning is performed using the BPX switch and MGX 8220 command line interfaces. This partitioning information is retrieved from the BPX switch by reading its port and trunk tables and from the MGX 8220 by reading the resource partitioning tables in the AUSM and FRSM MIBs.

The BPX switch line and routing or feeder trunk resources to be partitioned are:

•

•

•

•

•

LCN range

VPI range

Port Queues

Egress Queue pool size

MGX 8220 Feeder Trunk (BXM/BNI) resources to be partitioned are:
