Description: Enterasys Networks Transparent Web Cache Balancing (TWCB) MIB for configuring and monitoring server-side load balancing.

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-TWCB-MIB-2?

This Enterasys proprietary MIB covers Transparent Web Cache Balancing (TWCB), a server-side load-balancing feature that transparently redirects web traffic across a farm of caching servers. It exposes global statistics on the number of caches and web-cache server farms in use, active and historical binding counts (client-to-cache session mappings), and counters for exhausted or failed bindings. This is a performance/health monitoring MIB for the load-balancing subsystem: administrators can track etsysTwcbStatsBindingsCurrent versus etsysTwcbStatsBindingsHigh to gauge load, and etsysTwcbStatsBindingsExhausted/NoCaches to detect capacity exhaustion or cache-farm outages affecting web traffic redirection. No explicit dependency on other MIBs is indicated. It is typically deployed on Enterasys switches/appliances performing content/web-cache load balancing in front of a web-caching server farm. Engineers can download the ENTERASYS-TWCB-MIB-2 file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-TWCB-MIB-2. 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 switches/content-switching appliances

Monitoring Examples

Polling etsysTwcbStatsBindingsCurrent and etsysTwcbStatsBindingsHigh reveals whether the device is approaching its historical peak binding load, while a rising etsysTwcbStatsBindingsExhausted counter indicates clients are being denied cache bindings due to capacity limits. etsysTwcbStatsWebcacheActive versus etsysTwcbStatsCachesUsed shows how many of the configured caches are actually active, flagging a cache-farm member that has gone offline.

What Can Be Monitored

current/historical/total cache bindings
exhausted or failed binding counts
active web caches vs. configured caches
bindings-per-second rate
cache/server-farm utilization

How to Use in IPNetwork Monitor

Example using etsysTwcbStatsBindingsDeleted OID:

Select an Enterasys Networks switch (legacy, later Extreme Networks)/content-switching appliance (Transparent Web Cache Balancing) 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 etsysTwcbStatsBindingsDeleted into the Find box to locate it in the OID tree, then select it and click OK. This object contains the total number of TWCB bindings that have been deleted. 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.
