Cabletron Systems 2E48-27R 用户手册

 

Introduction

 

The 2E4X-27R provides IEEE 802.1D switching, IEEE 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 Modules (HSIMs).

802.1Q switching and SecureFast switching allow for future migration to 
Virtual Network technologies without requiring the replacement of 
existing equipment.

 

The 2E4X-27R is fully compliant with the IEEE 802.3 standard. The 
optional Fast Ethernet Interface Modules are fully compliant with the 
IEEE 802.3u standard.The 2E4X-27R provides IEEE 802.1D Spanning 
Tree Algorithm (STA) support to enhance the overall reliability of the 
network and protect against “loop” conditions. The 2E4X-27R 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 provide a wide array 
of statistical information to enhance troubleshooting. 

 

The 2E4X-27R has an internal clock that can maintain the current time 
and date beyond the year 1999.

 

LANVIEW diagnostic LEDs serve as an important troubleshooting aid by 
providing an easy way to observe the status of individual ports and overall 
network operations.
