Telecom Cisco Switch Pattern
The ServiceNow® Telecom Discovery application uses the Telecom Cisco Switch discovery pattern to find SNMP-based Cisco switches in the network. Discovering some of these resources requires updating the Telecommunications Discovery Patterns (TSOM Patterns) from the ServiceNow® Store.
Telecom Discovery uses the Telecommunications Discovery Patterns to run Horizontal Discovery. This Telecommunications Discovery Pattern uses a set of SNMP requests to find, classify, and discover network elements.
Telecom Cisco Switch pattern is part of the Telecommunications Discovery Patterns application (sn_tsom_patterns), which is part of TSOM Visibility.
