Rules for Adding Management Connections
This section describes the requirements for adding an inband ATM PVC for managing an MGX 8850
stand-alone node. A management connection lets a workstation connected through a router control
either the local MGX 8850 node or a remote MGX 8850 node that has no workstation. The typical
configuration has the connecting router feed an AUSM/B, FRSM, RPM, or PXM UNI port.
A management connection can be either a DAX con or a three-segment connection. The maximum
number of management connections is eight. The DAX con exists between a service module or PXM
UNI and port 34 of the local PXM. PXM port 34 is a reserved port for management connections on
a stand-alone node. The network in Figure 6-1 shows FRSMs in a feeder application.
A three-segment management connection has a:
1 Local segment between a near-end service module or PXM UNI and a PXM port in the
range 1–32.
2 Middle segment across the network cloud.
3 Local segment between a remote PXM port in the range 1–32 and port 34 of that same PXM.
The path from “A” to “B” in Figure 6-1 consists of three segments. A segment exists between the
FRSM and the PXM on each MGX 8850 switch. The middle segment exists between the BXMs at
the edges of the ATM cloud and may traverse BPX 8600 via nodes in the cloud. The VPI and VCI
at each BPX8600-series switch connected to an MGX 8850 feeder must match the VPI and VCI on
the slave endpoint of the connected PXM. The VPIs and VCIs at the endpoints of the middle segment
do not have to match. If you use the CLI rather than the Cisco WAN Manager application, add each
segment through the CLI at each switch.
