WCCP-MIB

Description: Manages Blue Coat WCCP (Web Cache Communication Protocol) service groups, routers, and cache redirection statistics.

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.

This is a Blue Coat device-specific MIB for monitoring WCCP (Web Cache Communication Protocol) on Blue Coat cache/proxy appliances that participate in transparent web caching behind a WCCP-enabled router. It exposes a WCCP-enabled flag and a per-service table of redirection statistics, including packets and bytes redirected at normal and low priority. Its monitoring value is software/service status: confirming WCCP is actually enabled and, more importantly, that traffic redirection counters are actively incrementing - flat or zero counters despite WCCP being enabled point to a broken WCCP negotiation or GRE tunnel between the router and the cache engine. It implements the Cisco-originated WCCP protocol as run on Blue Coat's own device, complementing (but distinct from) router-side WCCP implementations. It is deployed on Blue Coat ProxySG/cache appliances acting as WCCP cache engines for transparent web caching in enterprise networks, where WCCP-MIB SNMP monitoring confirms redirection is functioning correctly.

An admin would poll deviceWccpEnabled to confirm WCCP is active, then check deviceWccpValueTable indexed by deviceWccpIndex/deviceWccpServiceID for deviceWccpPacketsRedir and deviceWccpBytesRedir - flat or zero counters despite deviceWccpEnabled being true would indicate the router isn't redirecting traffic to this cache engine - while deviceWccpPacketsLowRedir/deviceWccpBytesLowRedir show lower-priority redirected traffic volume.
