Description: Altiga (Cisco VPN 3000) Telnet statistics MIB for monitoring Telnet management session counts and access events.

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 ALTIGA-TELNET-STATS-MIB?

ALTIGA-TELNET-STATS-MIB is a Cisco (originally Altiga Networks) MIB for the VPN 3000 Series concentrator that tracks statistics for Telnet-based management sessions on the device. It exposes counters for active, attempted, and successful Telnet sessions, along with inbound/outbound packet, octet, and drop counters for the Telnet management traffic. Its monitoring purpose is software/management-plane status: administrators track alTelnetStatsActiveSessions and alTelnetStatsAttemptedSessions versus alTelnetStatsSuccessfulSessions to detect failed login attempts or unauthorized access attempts against the device's management interface, and the drop-packet counters to catch abnormal Telnet traffic drops. It is a self-contained Cisco/Altiga management MIB with no apparent dependency on external standard MIBs. It is deployed on Cisco VPN 3000 Series concentrators where administrators use Telnet for device management and need visibility into that management channel's health and access attempts. Engineers can download the ALTIGA-TELNET-STATS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ALTIGA-TELNET-STATS-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

Cisco VPN 3000 Series concentrator (Altiga)

Monitoring Examples

An admin would poll alTelnetStatsActiveSessions to confirm the current number of open management Telnet sessions and compare alTelnetStatsAttemptedSessions against alTelnetStatsSuccessfulSessions to spot a spike in failed login attempts suggestive of a brute-force attack. alTelnetStatsInNetDropPackets/alTelnetStatsInNetDropOctets and alTelnetStatsOutNetDropPackets/alTelnetStatsOutNetDropOctets would be checked when a management session experiences unexpected disconnects, revealing whether packets are being dropped on the inbound or outbound path of the Telnet channel.

What Can Be Monitored

active Telnet sessions
attempted vs successful Telnet sessions
inbound/outbound Telnet packet and octet counts
inbound/outbound dropped packets and octets

How to Use in IPNetwork Monitor

Example using alTelnetStatsAttemptedSessions OID:

Select a Cisco (Altiga) VPN 3000 Series Concentrator (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type alTelnetStatsAttemptedSessions into the Find box to locate it in the OID tree, then select it and click OK. The number of attempts made to establish Telnet sessions. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
