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.
