What Is Dell-TELNET-MIB?
This Dell private enterprise MIB manages Telnet server access on Dell managed switches, covering login credentials, session timeout, banners, and per-session tracking of connected Telnet users. It exposes configuration data (password, idle timeout, login banners) alongside live session-state data (active session IDs, client source address, login time, and session status). Its use in device monitoring centers on software/service status: administrators can see how many Telnet sessions are open, who is connected and from where, and how long they have been logged in, which supports both security auditing and troubleshooting of stuck or unauthorized sessions. It has conceptual overlap with standard connection-tracking MIBs but is implemented as a fully independent Dell private structure. It is typically used on PowerConnect/N-series switches in environments where remote CLI access needs to be monitored or audited via SNMP. Engineers can download the Dell-TELNET-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-TELNET-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.
What Can Be Monitored
- active Telnet session count and IDs
- session client IP address
- session login time
- session status
- configured idle timeout
- login banner text
Supported Devices
- Dell PowerConnect/N-Series managed switch
Monitoring Examples
Walking rlTelnetUsersTable/rlTelnetUsersEntry exposes each active rlTelnetSessionId along with rlTelnetSessionClientAddressType, rlTelnetSessionClientAddress, and rlTelnetSessionLoginTime, letting an admin verify who is currently logged into the switch via Telnet and since when. Checking rlTelnetSessionStatus can reveal a hung or stale session, while rlTelnetTimeout and rlTelnetLoginBanner confirm the configured idle timeout and banner text presented to new connections.
