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 you
configure VLANs. Up to 1024 VLANs can be configured.
IEEE 802.1Q switching allows migration to Virtual Network technologies without requiring the
replacement of existing equipment.
1.10 STANDARDS COMPATIBILITY
The 5H102-48 and 5H103-48 modules are fully compliant with the IEEE 802.3, 802.3u, 802.3x,
802.1D, and 802.1Q standards. The modules provide IEEE 802.1D Spanning Tree Algorithm
(STA) support to enhance the overall reliability of the network and protect against “loop”
conditions. The modules support a wide variety of industry standard MIBs including RFC 2737
(MIB I), RFC 1213 (MIB II), RFC 1757 (RMON), and RFC 1493 (Bridge MIB). 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.
1.11 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.
