Overview The SRST 3.4 component of Cisco IOS is not capable of participating in network management using SNMP. The SRST 3.4 effort is to make these components SNMP visible and provide necessary network management functions. This Cisco IOS feature can be used in the deployed customer scenarios that use SNMP managers. The Cisco IOS SNMP Agent can provide the following features for the SRST modules: • Generate notifications/traps for various functionality failures • Provide objects that help monitor performance/load of some of the key features • Provide detailed configurations for help in fault isolation. • Provide the active registrations of IP phones and Session Initiation Protocol (SIP) phones • Publish statistics on Ephone lines and SIP phone lines • Provide ability to mask/unmask notification SRST 3.4 does not have product-specific network management capabilities. The SRST MIB addresses SNMP Management Information Base (MIB) development for generating asynchronous exception notifications/traps, displaying configurations, and monitoring performance for IP telephony management purposes. The SRST feature provides emergency back up IP phone call capabilities, as shown in Figure 1-1. OL-7959-01 Cisco SRST SNMP MIB Release 3.4 Guide 1-1
