7.4 Provisioning Intermediate-Path Performance Monitoring
Intermediate-Path Performance Monitoring (IPPM) allows you to transparently monitor traffic
originating on E-1, E-3, and DS-3 cards (Path Terminating Equipment) as it passes through STM-1,
STM-4, STM-16, and STM-64 cards (Line Terminating Equipment). To use IPPM, you create the VC4
circuit on the E-1, E-3 or DS-3 cards, then enable IPPM on the STM-N cards that carry the circuit.
Near-end performance monitoring data on individual VC4 payloads is available by enabling IPPM.
For example, suppose you have a VC4 circuit that originates and terminates on E-N cards at Nodes 1 and
4. You want to monitor the circuit as it passes through STM-N cards at Nodes 2 and 3. To do this, open
the STM-N card, select the Provisioning > VC4 tabs, and check Enable IPPM for the appropriate VC4,
in this example, Line 1, VC4 1 (Figure 7-6).
