1.13 SWITCHING OPTIONS
The module provides 802.1Q switching between all of the front panel interfaces. In the 802.1Q
mode (the default mode of operation), the module functions as an 802.1D switch until VLANs are
configured.
IEEE 802.1Q switching allows migration to Virtual Network technologies without requiring the
replacement of existing equipment.
1.14 STANDARDS COMPATIBILITY
The module is fully compliant with the IEEE 802.3, 802.3x, 802.1D, and 802.1Q standards. The
module provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall
reliability of the network and protect against “loop” conditions. The module supports a wide
variety of industry standard MIBs including RFC 1213 (MIB II), RFC 1573 (MIB II), RFC 1757
(RMON), RFC 1493 (Bridge MIB), RFC 1354 (FIB MIB), and RFC 1190 (Path MTU Discovery).
A full suite of Enterasys Networks Enterprise MIBs provide a wide array of statistical information
to enhance troubleshooting. For information on how to extract and compile individual MIBs,
contact Enterasys Networks.
1.15 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.
