Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.
Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.

Cisco SRST SNMP MIB Support
Survivable Remote Site Telephony (SRST) Cisco IOS feature is used for the remote office routers that
support from 24 to 720 users in a centralized CallManager processing environment, to back up IP phone
calls and provide 911 emergency access by the public switched telephone network (PSTN). Any SRST
user can leverage SRST MIBs for better management with Simple Network Management Protocol
(SNMP) support.
Feature History of the Cisco SRST MIB Feature
Finding Support Information for Platforms and Cisco IOS Software Images
Use Cisco Feature Navigator to find information about platform support and Cisco IOS software image
support. Access Cisco Feature Navigator at http://www.cisco.com/go/fn. You must have an account on
Cisco.com. If you do not have an account or have forgotten your username or password, click Cancel at
the login dialog box and follow the instructions that appear.
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.

Chapter 1 Cisco SRST SNMP MIB Support
Overview
Figure 1-1 SRST Router Deployment with Network Management Components
SRST provides backup redundancy for broadband deployment of IP telephony to small branch offices.
It can be used if Cisco CallManager is no longer in service due to a loss of WAN connectivity. SRST
continues to provide basic call processing and IP telephony service to phones that fall back to SRST.
The CISCO-SRST-MIB defines managed objects that pertain to SRST, SIP Registrar, and SIP phones.
The CISCO-SRST-MIB has dependency on existing Cisco IOS MIBs, especially on the
CISCO-CCME-MIB and the CISCO-VOICE-DIAL-CONTROL-MIB.
All of these MIBs are accessible from SNMP management software running on external SNMP
managers.
Design of the CISCO-SRST-MIB
The CISCO-SRST-MIB enables you to display configurations and monitor and send traps and
asynchronous notifications to the SNMP management applications.
The CISCO-SRST-MIB approach offers the following advantages over the CLI command approach:
•A more efficient use of network bandwidth
•Greater interoperability among vendors because standard SNMP protocols are used
The following paragraphs describe the CISCO-SRST-MIB structure.
Structure
The Structure of Management Information (SMI) is represented conceptually by a tree hierarchy.
Branches along the tree have short text strings and integers to identify them. Text strings describe object
names, and integers allow computer software to encode compact representations of the names.
The CISCO-SRST-MIB is part of the Cisco management group, which is part of
private.enterprise.cisco.ciscoMgmt.
