Description: Enterasys Networks MIB for configuring and monitoring firewall policies, rules, and connection tracking on Enterasys devices.

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 ENTERASYS-FIREWALL-MIB?

ENTERASYS-FIREWALL-MIB is a private Enterasys Networks MIB for configuring and monitoring firewall policies, connection timeouts, and interface-level firewall enablement on Enterasys network devices with integrated firewall functionality. It exposes global firewall configuration (protocol timeouts, authentication port/timeout, logging threshold) along with a per-interface table tracking where the firewall is enabled and when that changed. Its monitoring relevance covers both configuration status (is the firewall enabled, are timeouts set as expected) and operational/security status (recent changes to firewall-enabled interfaces), which matters for confirming a device's security posture and catching unexpected firewall disablement. It functions as a self-contained private security extension without explicit dependency on other standard MIBs. It is deployed on Enterasys devices that combine switching/routing with integrated firewall capability, typically at network edges requiring policy enforcement, usually starting with an ENTERASYS-FIREWALL-MIB download into the administrator's SNMP management platform.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-FIREWALL-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

  • Enterasys Networks device with integrated firewall (switch/router with security module)

Monitoring Examples

An administrator would poll etsysFWFirewallEnabled to confirm the firewall feature is globally active, and check etsysFWTcpTimeout, etsysFWUdpTimeout, and etsysFWIcmpTimeout to verify connection-tracking timeout values match security policy. The etsysFWFirewallOnIntfTable, tracked via etsysFWFirewallOnIntfLastChange, lets an operator see per-interface firewall enablement and detect if a specific interface's firewall protection was unexpectedly disabled, while etsysFWLoggingThreshold indicates the configured sensitivity for firewall event logging.

What Can Be Monitored

  • global firewall enabled state
  • TCP/UDP/ICMP connection timeout settings
  • per-interface firewall enablement and last-change time
  • firewall logging threshold
  • authentication port/timeout settings

How to Use in IPNetwork Monitor

Example using etsysFWPolicyRuleTrueEvents OID:

Select an Enterasys Networks switch (legacy, later Extreme Networks) with integrated firewall 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 etsysFWPolicyRuleTrueEvents into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of times since the device has restarted that the rule has been true during packet inspection. 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.
