Establishing the MGX 8220 to BPX Connection

This procedure must be performed on the BPX at BOTH ends of the connection (“A” and “B”). This

connection is established only once per shelf.

On the BPX:

1 Perform an uptrk command to enable the T3 line that connects to your MGX 8220 shelf.

For trunk number, specify the BNI trunk number used for the MGX 8220 T3 line.

2 Perform a cnftrk command.

This command configures the physical line parameters of the T3 line connecting the BNI in the

BPX switch and BNM in the MGX 8220 shelf. Refer to the Cisco WAN Switching Command

Reference for details.

3 Perform an addshelf command to enable the port to the MGX 8220 shelf.

For trunk number, specify the BNI trunk number used for the MGX 8220 T3 line. For shelf-type,

specify “A” for MGX 8220, specify the vpi (between 5 and 14) and vci (between 6 and 271) in

the vpi and vci fields.

NoteThe total number of cells for all queues should not exceed 10,000.

MGX 8220 Management through SNMP

The MGX 8220 shelf provides the ability to manage the shelf through Simple Network Management

Protocol (SNMP) commands. These commands are issued from an SNMP Manager which accesses

the MGX 8220 shelf either through the Ethernet port, the control port, or in-band connection.

Each ASC and service module in the shelf contains an SNMP agent and a Management Information

Base (MIB) for that module. The SNMP agent responds to GET, GET NEXT and SET commands

from the SNMP Manager, thereby providing the user with the ability to interrogate and update the

MIB.

All messages from the SNMP Manager are checked for the correct Community String as follows:

• Messages to the active ASC must have a community string of AXIS_ASC_ACTIVE

• Messages to the standby ASC must have a community string of AXIS_ASC_STANDBY

• Messages to service module must have a community string of AXIS_SM-xx; where xx is the

service module slot number (5 through 14)

• Messages to the active BNM must have a community string of AXIS_BNM_ACTIVE

• Messages to the standby ASC must have a community string of AXIS_BNM_STANDBY
