1.13 SWITCHING OPTIONS
In the 802.1Q mode (the default mode of operation), the module functions as an 802.1D switch
until VLANs are configured.
The module provides 802.1Q switching or SecureFast Switching (SFS) Virtual Network Services
between all of the GPIM interfaces when the module is installed in a 6C105 SmartSwitch 6000
chassis. IEEE 802.1Q switching and SecureFast switching allow migration to Virtual Network
technologies without requiring the replacement of existing equipment.
When the module is installed in a 6C105 SmartSwitch 6000 chassis, SFS functionality is available
for the module. SFS functionality is not available in the Matrix E7 chassis.
1.14 STANDARDS COMPATIBILITY
The module is fully compliant with the IEEE 802.3z, 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 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.
