Cabletron Systems 9E531-24 - Manual (Page 18)

Introduction
1-6
Standards Compatibility
The 9E531-24 is fully compliant with the IEEE 802.3, 802.3x, 802.1Q, and 802.1p
standards. The 9E531-24 provides IEEE 802.1D Spanning Tree Algorithm (STA)
support to enhance the overall reliability of the network and protect against
“loop” conditions. The 9E531-24 supports a wide variety of industry standard
MIBs including RFC 1573 (MIB II), RFC 1271 (RMON), RFC 1493 (Bridge MIB),
RFC 1354 (FIB MIB), and RFC 1190 (Path MTU Discovery). A full suite of
Cabletron Systems Enterprise MIBs provide a wide array of statistical information
to enhance troubleshooting.
For information about how to extract and compile individual MIBs, contact
Cabletron Systems.
GARP Switch Operation
Some or all ports on the switch may be activated to operate under the Generic
Attribute Registration Protocol (GARP) applications, GARP VLAN Registration
Protocol (GVRP) and/or GARP Multicast Registration Protocol (GMRP).
GARP is a protocol, or set of rules, that outlines a mechanism for propagating the
port state and/or user information throughout a bridged LAN to keep track of
users and VLANs on the network fabric. MAC bridges and end users alike can
take part in the registration and de-registration of GARP attributes such as VLAN
and multicast group membership.
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.
Year 2000 Compliance
The 9E531-24 module and the SmartSwitch 9000 chassis have an internal clock
that can maintain the time and date beyond the year 1999.
