Chapter 1: Introduction1-4DLEHF-MA User’s GuideLocal Management is accessible through the RS232 COM port on thefront panel using a local VT100 terminal, or a remote VT100 terminal viaa modem connection, and in-band via a Telnet connection. In-bandremote management is possible through any SNMP compliant NetworkManagement Software.1.1.5 Switching OptionsThe DLEHF-MA provides IEEE 802.1D switching or IEEE 802.1Qswitching between the two Fast Ethernet Interface Modules and HighSpeed Interface Modules (HSIMs).T HE 802.1Q switching option allows for migration to Virtual Networktechnologies without requiring the replacement of existing equipment.1.1.6 Standards CompatibilityThe DLEHF-MA is fully compliant with the IEEE 802.3 standard. Theoptional Fast Ethernet Interface Modules are fully compliant with theIEEE 802.3u standard. The DLEHF-MA provides IEEE 802.1D SpanningTree Algorithm (STA) support to enhance the overall reliability of thenetwork and protect against “loop” conditions. It also supports a widevariety of industry standard MIBs including RFC 1213 (MIB II),RFC 1271 (RMON), RFC 1317 (RS232 MIB), RFC 1493 (Bridge MIB),RFC 1354 (FIB MIB), and RFC 1573 (Evolution of MIB II Interfaces). Afull suite of Cabletron Enterprise MIBs provide a wide array of statisticalinformation to enhance troubleshooting.1.1.7 Year 2000 ComplianceThe DLEHF-MA has an internal clock that can maintain the current timeand date beyond the year 1999.
