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.
Management Information Base (MIB) Support
The 9H531-18 and 9H532-18 modules provides MIB support including:
• RMON (RFC 1271)
• IETF MIB II (RFC 1573)
• IETF Bridge MIB (RFC 1493)
and a host of other Cabletron Enterprise MIBs.
LANVIEW LEDs
The 9H531-18 and 9H532-18 module uses LANVIEW – the Cabletron Systems
built-in visual diagnostic and status monitoring system. With LANVIEW LEDs,
you can quickly identify, at-a-glance, system status as well as the device, port, and
physical layer status. Two LEDs indicate the transmission and reception of data
from the INB SmartSwitch 9000 backplane connection. Each of the 18 Ethernet
front panel ports features two LEDs per port to indicate the port’s Administrative
status (enabled/ disabled), LINK status (Link/Nolink), and Data Activity
(receiving and transmitting data).
Year 2000 Compliance
The 9H531-18 and 9H532-18 module and the SmartSwitch 9000 chassis have an
internal clock that can maintain the time and date beyond the year 1999.
For a complete list of supported MIBs, refer to the release notes provided with the
9H531-18 and 9H532-18.
