Guidelines to
Using the
Channel
Operating
Modes
Here are the guidelines to using the channel operating
modes:
ˆ Different channels on the module can operate in
different modes.
ˆ The operating modes do not block or interfere with the
flow of traffic between the two ports of a channel, and so
can be used during normal network operations.
ˆ The MissingLink mode is intended for situations where
the ports of a channel are connected to managed
devices, such as managed Fast Ethernet switches, that
can react to the loss of a link and perform a specific
action, such as send out an SNMP trap.
ˆ Allied Telesis does not recommend using the Smart
MissingLink mode on a channel connected to managed
devices during normal operations of the channel. As
explained in “Smart MissingLink Mode” on page 33, this
mode pulses the transmitter of a channel port when the
link is lost on the companion port. A pulsing transmitter
may cause problems for a managed device.
ˆ The Link Test and Smart MissingLink modes are
particularly useful when there has been a link failure to a
channel port and you want to use the Link LEDs to
identify which port in a channel is unable to establish a
link with its networking device.
