6E12X-26 and 6E13X-25 Overview
6E128-26, 6E138-25, 6E129-26 and 6E139-25 User’s Guide 1-5
1.3.4 Switching Options
The 6E12X-26 and 6E13X-25 provide 802.1D switching (bridging),
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).
SecureFast switching and 802.1Q switching allow for future migration to
Virtual Network technologies without requiring the replacement of
existing equipment.
1.3.5 Standards Compatibility
The 6E12X-26 and 6E13X-25 are fully compliant with the IEEE 802.3
standard. The optional Fast Ethernet Interface Modules are fully
compliant with the IEEE 802.3u standard. The 6E12X-26 and 6E13X-25
provide IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance
the overall reliability of the network and protect against “loop”
conditions. The 6E12X-26 and 6E13X-25 support 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.
1.3.6 LANVIEW Diagnostic LEDs
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.
Chapter 4 provides details about the 6E12X-26 and
6E13X-25 LANVIEW LEDs.
1.3.7 Year 2000 Compliant
The 6E12X-26 and 6E13X-25 have an internal clock that can maintain the
current time and date beyond the year 1999.
