Chapter 1: Introduction
The RAD requests start out at an interval of 1 second. The interval then doubles after every transmission until an interval of 300 seconds is reached. At this point, the interval remains at 300 seconds. The RAD requests continue until an IP address is received from a BootP server, or an IP address is entered using Local Management.
1.3.6Management
Management of the 2E43-51 is accomplished using SNMP compliant management tools for in-band Local Management. Out-of-band Local Management is provided through the RJ45 COM port on the front panel using a VT100 terminal or a VT100 terminal emulator. In-band remote management is possible through any SNMP compliant Network Management Software.
Local Management provides the ability to manage the 2E43-51 and any of the optional Fast Ethernet Interface Modules installed in ports 5 and 6, and the optional High Speed Interface Module (HSIM).
The associated HSIM user’s guide provides detailed information about the HSIM Local Management.
1.3.7Switching Options
The 2E43-51 provides 802.1D switching, 802.1Q switching or SecureFast Switching Virtual Network Services between all of the front panel interfaces including Fast Ethernet Interface Modules and High Speed Interface Module (HSIM).
IEEE 802.1Q switching and SecureFast switching allow for future migration to Virtual Network technologies without requiring the replacement of existing equipment.
1.3.8Standards Compatibility
The 2E43-51 provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 2E43-51 also supports 100BASE-TX and 100BASE-FX Fast Ethernet standards and 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 provide a wide array of statistical information to enhance troubleshooting.
