50 Using the Console Interface
Do Nothing, Blocking or Blocking-Trap. The Do
Nothing setting causes the switch to operate normally,
in other words, ignore the broadcast storm condition.
The Blocking setting causes the port to drop all
broadcast frames, thus isolating the broadcast storm.
Blocking-Trap performs the same action as Blocking,
except it also sends a trap to the designated Trap
Recipient informing them of the situation.
♦
Broadcast Storm Falling Action This setting will be
activated when a Broadcast Storm Rising Action has
occurred and the switch detects that port utilization
has dropped below 10%. This setting can be configured
to Do Nothing, Forwarding or Forwarding-Trap. The
Do Nothing setting causes the
switch to operate
normally, in other words, ignore the situation. If the
port had met the Broadcast Storm Rising Action
criteria and started Blocking broadcast packets, it
will continue doing so. The Forwarding setting causes
the port to begin forwarding broadcast frames, thus
removing the Blocking state imposed by the Broadcast
Storm Rising Action. Forwarding-Trap performs the
same action as Forwarding, except it also sends a trap
to the designated Trap Recipient informing them of
the situation.
Configure Port Mirroring
The Port Mirroring Configuration screen allows you to
copy frames transmitted and received on a port and
redirect the copies to another port. You can attach a
monitoring device to the mirrored port, such as a sniffer or
an RMON probe, to view details about the packets passing
through the first port. This is useful for network
monitoring and troubleshooting purposes.
