Introduction1-6Standards CompatibilityThe 9E531-24 is fully compliant with the IEEE 802.3, 802.3x, 802.1Q, and 802.1pstandards. 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 standardMIBs 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 ofCabletron Systems Enterprise MIBs provide a wide array of statistical informationto enhance troubleshooting.For information about how to extract and compile individual MIBs, contactCabletron Systems.GARP Switch OperationSome or all ports on the switch may be activated to operate under the GenericAttribute Registration Protocol (GARP) applications, GARP VLAN RegistrationProtocol (GVRP) and/or GARP Multicast Registration Protocol (GMRP).GARP is a protocol, or set of rules, that outlines a mechanism for propagating theport state and/or user information throughout a bridged LAN to keep track ofusers and VLANs on the network fabric. MAC bridges and end users alike cantake part in the registration and de-registration of GARP attributes such as VLANand multicast group membership.LANVIEW Diagnostic LEDsLANVIEW diagnostic LEDs serve as an important troubleshooting aid byproviding an easy way to observe the status of individual ports and overallnetwork operations.Year 2000 ComplianceThe 9E531-24 module and the SmartSwitch 9000 chassis have an internal clockthat can maintain the time and date beyond the year 1999.
