What Is Dell-VRTX-TELNET-MIB?
This private MIB manages Telnet remote-access configuration and active session tracking on the Dell PowerEdge VRTX chassis switch module, using the RAD-derived "rl"-prefixed embedded switch OS. It exposes configuration objects such as the Telnet password, idle timeout, and login banners, plus a table of currently connected Telnet sessions with client address and login time. For software/service status monitoring it is directly useful for security auditing: the rlTelnetUsersTable (rlTelnetSessionId, rlTelnetSessionClientAddress, rlTelnetSessionLoginTime, rlTelnetSessionStatus) shows exactly who is logged into the device's CLI and since when, letting an administrator detect unauthorized or forgotten open sessions. It is a vendor-private supplement to standard SNMP-based device management and works alongside interface/IP MIBs to identify client source addresses. It is deployed on Dell VRTX chassis switch management interfaces wherever Telnet CLI access is enabled for administration, making Dell-VRTX-TELNET-MIB SNMP monitoring a useful check for unauthorized CLI sessions.
IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-VRTX-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 sessions
- session client address and login time
- session status
- Telnet idle timeout
- login banner configuration
Supported Devices
- Dell PowerEdge VRTX chassis switch module
Monitoring Examples
A security-conscious administrator would poll rlTelnetUsersTable/rlTelnetUsersEntry to enumerate active sessions by rlTelnetSessionId, checking rlTelnetSessionClientAddress and rlTelnetSessionLoginTime to spot an unexpected or long-lived connection, and rlTelnetSessionStatus to confirm whether a session is still active or stale. rlTelnetTimeout would be checked to confirm idle sessions are set to disconnect automatically. An unusual client address logged in outside change windows would indicate a possible unauthorized access attempt.
