Jumper Selectable Ring Speed
The BRIM-T6 has a ring speed selection jumper on its component board
that you can use to select operating ring speeds of either 4 or 16 megabits
per second (4 or 16 Mbps). See Section 2.3 for instructions on setting the
ring speed for the BRIM-T6.
Bridge/Routing Protocols
The BRIM-T6 provides Source Routing Transparent (SRT) bridging
between any of the channels or ports in its host MIM or hub and the Token
Ring. BRIM-T6 routing is determined by the routing protocols supported
by the firmware of the host device.
Spanning Tree Algorithm (STA) Compliance
The BRIM-T6 operates in compliance with the functional specifications of
the 802.1d STA, which is included in the firmware of the host device in
which the BRIM-T6 is installed. The STA is used to manage primary and
backup bridges and to maintain the reliability of the multi-bridged
internetwork by detecting and preventing potential data loops.
BRIM-T6 Management
The host device in which the BRIM-T6 is installed provides Local
Management (LM) applications for administering BRIM-T6
bridge/routing functions. The operation of the BRIM-T6 can also be
managed by remote SNMP applications such as Remote LANVIEW and
SPECTRUM. See the documentation included with the host device or
remote management application for information on how to administer
bridge/routing functions.
LANVIEW LEDs
The LANVIEW LEDs on the front panel of the BRIM-T6, together with
the LED on an installed TPIM, provide an at-a-glance means of monitoring
the operational status of the BRIM-T6. LEDs indicate, for example,
network connection status, data transmission activity, and ring speed
operation. See Chapter 4 for more information about LEDs.
