1.3.4 Remote Monitoring (RMON) The 2H22-08R supports all Ethernet RMON groups, which include
Statistics, Alarms, Events and History as the default groups enabled on all
ports, and Capture, Filter, and Host as the groups that are off 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.
1.3.5 Switching Options The 2H22-08R provides traditional Switching (802.1D), IEEE 802.1Q, or

Switching Virtual Network Services between all of the front
panel interfaces including Fast Ethernet Interface Modules. S

Switching and IEEE 802.1Q allows for migration to Virtual Network
technologies without requiring the replacement of existing equipment.
1.3.6 Standards Compatibility The 2H22-08R provides IEEE 802.1, 802.1u, 802.1D and DEC Spanning
Tree Algorithm (STA) support to enhance the overall reliability of the
network and protect against “loop” conditions. The 2H22-08R supports a
wide variety of industry standard MIBs including RFC 1213 (MIB II),
RFC 1757 (RMON), RFC 1493 (Bridge MIB), and RFC 1354 (FIB MIB).
A full suite of Cabletron Systems Enterprise MIBs provides a wide array
of statistical information to enhance troubleshooting.
1.3.7 Year 2000 Compliant The 2H22-08R has an internal clock that can maintain the current time
and date beyond the year 1999.
1.3.8 LANVIEW Diagnostic LEDs The various conditions of the LANVIEW diagnostic LEDs serve as
important troubleshooting aids. They provide an easy way to observe the
transmit and receive status of individual ports and overall network
operations such as system status, switching configuration, and Fast
Ethernet channel usage.
