Managing the Hub 2-29
Using the EMM-E6 Hub View
Device Configuration
This polling interval controls how often a survey is conducted of the type of
equipment installed in the EMM-E6-managed hub; information from this poll
would change the Hub View to reflect the addition and/or removal of a MIM or
MIMs.
Port Operational State
This polling interval controls the update of the information displayed in the Port
Status boxes for each port in the hub. Port state information includes link state
(the color code) and admin state (on or off).
Statistics
This polling interval controls how often the information displayed in the Port
Status boxes is updated when the Port Display Form is set to a rate or percentage,
and how often the Network, Module, and Port statistics counts are updated.
Configuring FNB Connections
Cabletron Systems’ MultiChannel technology allows you to configure multiple,
separately-repeated channels in the same MMAC. Hubs which incorporate the
Flexible Network Bus (FNB) design have three internal channels: the original
power and management channel (designated as Channel A), and two additional
Ethernet channels (designated as Channel B and Channel C) that are repeated
separately.
Cabletron’s original Media Interface Modules (MIMs) are automatically
configured to operate on the original backplane channel, Channel A. However,
Cabletron Systems’ latest family of MIMs — Repeater, or RIC, MIMs (the
FORMIM, CXRMIM, TPRMIM, and TPXMIM) — can be selectively configured to
operate on the B or C channel, or, since they provide their own repeater
functionality, in a stand-alone mode.
In addition, the newest member of the RIC MIM family — the TPXMIM —
provides the ability to assign the entire board to a channel (bank switching), or to
assign each individual port to a channel (port assignment). Also unique to the
TPXMIM is the ability to assign each of its ports or the board as a whole to
Channel A. The following sections describe how to configure the FNB connections
for these MIMs.
NOTE
SPMA generates network traffic when it retrieves the above-described information; keep
in mind that shorter intervals mean increased network traffic. Range limits for these
polling times are 0-999,999 seconds; however, an entry of 0 will be treated as a 1.
