Service and connectivity diagnostics

STM OAM diagnostics for troubleshooting

This chapter documents how to troubleshoot service and general connectivity problems when there is no associated alarm condition.

You can use the NFM-P Service Test Manager, or STM, OAM diagnostic tools for network troubleshooting and for verifying compliance with SLAs. The STM provides the ability to group OAM diagnostic tests into test suites for more comprehensive fault monitoring and troubleshooting. A test suite can perform end-to-end testing of a customer service and the underlying network transport elements. The use of test suites is especially valuable when multiple objects of the same type require testing. Test suites can be scheduled to run on a regular basis to provide continual network performance feedback. See the NSP NFM-P Classic Management User Guide for information about using the STM and creating scheduled tasks.
