Chapter 1: Introduction1-66H128-08 and 6H129-08 User’s Guide1.3.5 Remote Monitoring (RMON)The 6H12X-08 supports all Ethernet RMON groups, which includeStatistics, Alarms, Events and History. These groups are enabled on allports by default.Cabletron Systems RMON Actions is a vendor specific extension ofRMON and provides the ability to set an “Action” on any SNMP MIBvariable. The Action can be triggered by any RMON Event and/or Alarm.The Action can be, for example, to turn a MIB-2 interface off if abroadcast threshold is crossed.1.3.6 Switching OptionsThe 6H12X-08 provides IEEE 802.1D switching, IEEE 802.1Q, orSecureFast Switching Virtual Network Services between all of the frontpanel interfaces including Fast Ethernet Interface Modules. SecureFastSwitching and IEEE 802.1Q allow for migration to Virtual Networktechnologies without requiring the replacement of existing equipment.1.3.7 Standards CompatibilityThe 6H12X-08 meets 802.3u specifications, and provides IEEE 802.1Dand DEC Spanning Tree Algorithm (STA) support to enhance the overallreliability of the network and protect against “loop” conditions. The6H12X-08 supports a wide variety of industry standard MIBs includingRFC 1213 (MIB II), RFC 1757 (RMON), RFC 1371 (RS232 MIB),RFC 1493 (Bridge MIB) and RFC 1354 (FIB MIB). A full suite ofCabletron Systems Enterprise MIBs provide a wide array of statisticalinformation to enhance troubleshooting.1.3.8 Year 2000 CompliantThe 6H12X-08 has an internal clock that can maintain the time and datebeyond the year 1999.
