Description: Monitors Avaya CIG (Communication Infrastructure Group) client sessions and connectivity.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CIG-CLIENTS-MIB?

CIG-CLIENTS-MIB is an Avaya proprietary MIB that manages client-side network services on Avaya CIG (Communication Infrastructure Group) devices, specifically the DHCP client used to obtain dynamic IP configuration per interface and the DNS resolver client used for name resolution. The data it exposes falls into configuration and operational-status categories: DHCP client bindings per interface and DNS resolver mode, retry counts, timeout values, and the list of configured DNS servers. From a monitoring standpoint it is primarily a software/service-status MIB, letting an administrator confirm whether an interface has successfully obtained an address via DHCP and whether the DNS resolver is operating with a healthy, reachable server list rather than timing out or falling back. It is a self-contained Avaya extension and does not appear to require companion IETF MIBs beyond the standard interfaces model implied by its per-interface DHCP table. It is typically deployed on Avaya voice/communication infrastructure gateways and appliances where reliable address assignment and name resolution are prerequisites for call control and signaling to function. Engineers can download the CIG-CLIENTS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CIG-CLIENTS-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

  • Avaya CIG (Communication Infrastructure Group) appliance
  • Avaya voice/communication gateway

Monitoring Examples

An administrator polls cigDhcpClientsTable / cigDhcpClientsEntry to verify each managed interface has a valid DHCP lease, and checks cigDnsResolverMode along with cigDnsResolverRetry and cigDnsResolverTimeout to see if resolution attempts are being retried excessively. Walking cigDnsResolverDnsServersListTable / cigDnsResolverDnsServersListEntry shows the configured DNS server list and each entry's cigDnsResolverDnsServersListRowStatus, revealing whether a server was removed or is stuck in a notReady state. Repeated retries combined with a stale or empty server list would point to a misconfigured or unreachable DNS infrastructure affecting the device's ability to resolve names for signaling.

What Can Be Monitored

  • DHCP client lease status per interface
  • DNS resolver mode
  • DNS resolver retry count
  • DNS resolver timeout
  • configured DNS server list
  • DNS server row status
