CISCOSB-TELNET-MIB

Description: Configures Telnet server access controls and session limits on Cisco Small Business managed 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.

This is a Cisco Small Business proprietary MIB governing Telnet remote-access management on their managed switch line. It exposes configuration objects (password, idle timeout, login banners) as well as an operational table of currently logged-in Telnet users showing session ID, client address, and login time. Though primarily a security/access-control MIB rather than a hardware-health MIB, it does let an operator monitor software/service status in the sense of active management sessions - how many users are logged in, from where, and for how long - which is useful for detecting unauthorized or stale sessions. It is a self-contained proprietary MIB with no significant dependency on other standard MIBs beyond basic SNMPv2-SMI conventions. It is deployed on Cisco Small Business switches (Sx200/300/500 series) wherever administrators need to audit or restrict Telnet-based CLI access. Engineers can download the CISCOSB-TELNET-MIB file directly to load it into their MIB browser.

Polling rlTelnetUsersTable returns one rlTelnetUsersEntry per active session, with rlTelnetSessionClientAddressType/rlTelnetSessionClientAddress identifying the connecting host and rlTelnetSessionLoginTime showing session age; an admin could use this to spot a session left open far longer than expected or a login from an unexpected IP. rlTelnetSessionStatus reflects whether a session is active or invalid, useful for confirming forced logouts took effect. rlTelnetTimeout and rlTelnetLoginBanner/rlTelnetSecondLoginBanner are configuration items an admin verifies match intended security policy.
