Switching Options

The 9H532-24, 9H533-24, 9H531-24 and 9H539-24 provide IEEE Standard-based

802.1switching or SecureFast Switching Virtual Network Services. In the 802.1 mode (the default mode of operation), the switch functions as an 802.1D switch. When until VLANs are conÞgured, it operates as an 802.1Q switch.

Standards Compatibility

The 9H532-24, 9H533-24, 9H531-24 and 9H539-24 are fully compliant with the IEEE 802.3, 802.3x, 802.3u, 802.1Q, and 802.1p standards. The 9H532-24, 9H533-24, 9H531-24 and 9H539-24 provide IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against ÒloopÓ conditions. The 9H532-24, 9H533-24, 9H531-24 and 9H539-24 support 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.

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
