2H22-08R Overview
1.3.4Remote 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.
1.3.5Switching Options
The 2H22-08R provides traditional Switching (802.1D), 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 allows for migration to Virtual Network technologies without requiring the replacement of existing equipment.
1.3.6Standards 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.
1.3.7Year 2000 Compliant
The 2H22-08R has an internal clock that can maintain the current time and date beyond the year 1999.
1.3.8LANVIEW 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. Chapter 4 provides details about the 2H22-08R LANVIEW LEDs.
