What Is CISCO-GSLB-TC-MIB?
CISCO-GSLB-TC-MIB is a Cisco support MIB defining Textual Conventions and OBJECT-IDENTITIES used by the CISCO-GSLB-SYSTEM-MIB, CISCO-GSLB-DNS-MIB, and CISCO-GSLB-HEALTH-MON-MIB modules that together manage Global Server Load Balancing (GSLB) devices. It contains no runtime data objects itself, instead defining shared data types and acronym-based conventions (such as Content Routing Agent/CRA concepts) used across the GSLB MIB family. Because it holds no data, it does not itself report hardware/software status; that is the role of the three GSLB MIBs that depend on it, which cover system state, DNS-based routing, and health monitoring of load-balanced sites. Those three sibling MIBs explicitly depend on this module for consistent type definitions, and a CISCO-GSLB-TC-MIB download is typically obtained alongside those three dependent GSLB MIBs, since this module alone defines no pollable objects. It is used in multi-site data center deployments where Cisco GSLB devices distribute traffic across geographically distributed sites based on DNS and health checks.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-GSLB-TC-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Cisco Global Server Load Balancing (GSLB) device
Monitoring Examples
This module defines only Textual Conventions and OBJECT-IDENTITIES shared by CISCO-GSLB-SYSTEM-MIB, CISCO-GSLB-DNS-MIB, and CISCO-GSLB-HEALTH-MON-MIB; it has no sample runtime objects of its own, so no concrete monitoring scenario applies here — actual GSLB health and DNS routing status is monitored through those dependent MIB modules.

| ciscoGslbTcMIB | 1.3.6.1.4.1.9.9.583 | This MIB module defines Textual Conventions and OBJECT-IDENTITIES for use in documents defining management information base (MIBs) modules for managing CISCO-GSLB-SYSTEM-MIB, CISCO-GSLB-DNS-MIB and CISCO-GSLB-HEALTH-MON-MIB (These MIB modules are used for a Global Server Load Balancing device(GSLB)). Acronyms and their description: CRA : Content Routing Agent - software that provides information to a GSLB device for content routing decisions and handles content routing requests from the GSLB device. D-Proxy : It is a local name server of the client which has initiated a DNS query for a domain. VIP : Virtual IP Addresses - they are used by server load balancing devices to represent content hosted on one or more servers under their control. The use of VIPs is to route content to the proper requesting host without exposing the device's internal IP address. Keepalive : A keepalive is an interaction between GSLB device and another device using a commonly supported protocol. It is used to periodically check if a resource is still active. DNS race : It is a method of resolving the proximity of the CRAs from the D-Proxy. In this method the GSLB device sends a request to all the CRAs directing them to respond to the D-Proxy at at the same time. The first response received by the D-proxy is, by default, considered to be the most proximate. |
