RC-TACACS-MIB

Description: Manages TACACS+ server configuration and authentication accounting on Bay Networks Rapid-City series switches.

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.

RC-TACACS-MIB is a Bay Networks/Nortel enterprise MIB for the Rapid-City switch family, covering TACACS+ authentication, authorization, and accounting (AAA) client configuration. It exposes global TACACS+ enable state, server-table entries (address/type per server), accounting and authentication mode settings, and NNCLI command-authorization configuration including which privilege levels require authorization. From a monitoring standpoint it is primarily a software/service-status MIB for the switch's AAA subsystem -- tracking rcTacacsGlobalLastUserName/Address to see the most recent authentication attempt and confirming server reachability/configuration is intact, which matters for detecting authentication outages that could lock administrators out of device management. It has no dependency on external standard MIBs, being a self-contained Nortel enterprise TACACS+ client implementation. It is deployed on Rapid-City/Ethernet Routing Switch devices in enterprise networks that centralize administrative authentication through TACACS+ servers. Engineers can download the RC-TACACS-MIB file directly to load it into their MIB browser.

An administrator would check rcTacacsServerTable (rcTacacsServerEntry) for rcTacacsServerAddress and rcTacacsServerAddressType to confirm the configured TACACS+ servers are correct, and monitor rcTacacsGlobalLastUserName/rcTacacsGlobalLastAddress to audit the most recent login attempt against the switch. If rcTacacsGlobalEnable is set but authentication requests are failing, it would suggest a TACACS+ server reachability problem, which is critical since it affects administrative access to the device itself. rcTacacsNncliCommandAuthorizationLevels confirms which CLI privilege levels are subject to command authorization checks.
