Introduction
1-6 6H128-08 and 6H129-08 User’s Guide
1.3.5 Remote Monitoring (RMON)
The 6H12X-08 supports all Ethernet RMON groups, which include
Statistics, Alarms, Events and History. These groups are enabled on all
ports by default.
Cabletron Systems RMON Actions is a vendor specific extension of
RMON and provides the ability to set an “Action” on any SNMP MIB
variable. 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 a
broadcast threshold is crossed.
1.3.6 Switching Options
The 6H12X-08 provides IEEE 802.1D switching, IEEE 802.1Q, or
SecureFast Switching Virtual Network Services between all of the front
panel interfaces including Fast Ethernet Interface Modules. SecureFast
Switching and IEEE 802.1Q allow for migration to Virtual Network
technologies without requiring the replacement of existing equipment.
1.3.7 Standards Compatibility
The 6H12X-08 meets 802.3u specifications, and provides IEEE 802.1D
and DEC Spanning Tree Algorithm (STA) support to enhance the overall
reliability of the network and protect against “loop” conditions. The
6H12X-08 supports a wide variety of industry standard MIBs including
RFC 1213 (MIB II), RFC 1757 (RMON), RFC 1371 (RS232 MIB),
RFC 1493 (Bridge MIB) and RFC 1354 (FIB MIB). A full suite of
Cabletron Systems Enterprise MIBs provide a wide array of statistical
information to enhance troubleshooting.
1.3.8 Year 2000 Compliant
The 6H12X-08 has an internal clock that can maintain the time and date
beyond the year 1999.
