Chapter 1: Introduction
1-6 2M46-04R/2M46-04RDC User’s Guide
1.3.7 Switching
The 2M46-04R provides traditional switching (802.1D), IEEE 802.1Q
switching, or SecureFast Switching (SFS) Virtual Network Services
between all of the optional Fast Ethernet Interface Modules and High
Speed Interface Modules (HSIMs). SFS and 802.1Q switching allow for
migration to Virtual Network technologies without requiring the
replacement of existing equipment.
1.3.8 Standards Compatibility
The optional Fast Ethernet Interface Modules are fully compliant with the
IEEE 802.3u standard.The 2M46-04R provides IEEE 802.1D Spanning
Tree Algorithm (STA) support or DEC spanning tree support to enhance
the overall reliability of the network and protect against “loop”
conditions. The 2M46-04R supports a wide variety of industry standard
MIBs including RFC 1213 (MIB II), RFC 1271 (RMON), RFC 1317
(RS232 MIB), RFC 1493 (Bridge MIB), RFC 1573 (Evolution of MIB II
Interfaces), and RFC 1354 (FIB MIB). A full suite of Cabletron Systems
Enterprise MIBs provide a wide array of statistical information to
enhance troubleshooting.
1.3.9 Year 2000 Compliance
The 2M46-04R has an internal clock that can maintain the time and date
beyond the year 1999.
1.3.10 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 2M46-04R
LANVIEW LEDs.
