Chapter 1: Introduction1-62E43-51/2E43-51R User’s GuideThe RAD requests start out at an interval of 1 second. The interval thendoubles after every transmission until an interval of 300 seconds isreached. At this point, the interval remains at 300 seconds. The RADrequests continue until an IP address is received from a BootP server, oran IP address is entered using Local Management.1.3.6 ManagementManagement of the 2E43-51 is accomplished using SNMP compliantmanagement tools for in-band Local Management. Out-of-band LocalManagement is provided through the RJ45 COM port on the front panelusing a VT100 terminal or a VT100 terminal emulator. In-band remotemanagement is possible through any SNMP compliant NetworkManagement Software.Local Management provides the ability to manage the 2E43-51 and any ofthe 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 aboutthe HSIM Local Management.1.3.7 Switching OptionsThe 2E43-51 provides 802.1D switching, 802.1Q switching or SecureFastSwitching Virtual Network Services between all of the front panelinterfaces including Fast Ethernet Interface Modules and High SpeedInterface Module (HSIM).IEEE 802.1Q switching and SecureFast switching allow for futuremigration to Virtual Network technologies without requiring thereplacement of existing equipment.1.3.8 Standards CompatibilityThe 2E43-51 provides IEEE 802.1D Spanning Tree Algorithm (STA)support to enhance the overall reliability of the network and protectagainst “loop” conditions. The 2E43-51 also supports 100BASE-TX and100BASE-FX Fast Ethernet standards and a wide variety of industrystandard MIBs including RFC 1213 (MIB II), RFC 1757 (RMON),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.
