2E4X-27 Overview
1.4.6Switching Options
The 2E4X-27 provides 802.1D Switching, 802.1Q switching or SecureFast Switching Virtual Network Services between all of the front panel interfaces including any installed Fast Ethernet Interface Modules and HSIM.
802.1Q switching and SecureFast switching allow for future migration to Virtual Network technologies without requiring the replacement of existing equipment.
1.4.7Standards Compatibility
The 2E4X-27 provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 2E4X-27 supports a wide variety of industry standard MIBs including RFC 1213 (MIB II), RFC 1757 (RMON), RFC 1371 (RS232 MIB), 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.
1.4.8Year 2000 Compliant
The 2E4X-27 has an internal clock that can maintain the current time and date beyond the year 1999.
