Extreme Networks EAS 100-24t Switch CLI Manual
<portlist> - Used to specify a range of ports to be configured for traffic control.
all - Specifies all ports are to be configured for traffic control on the switch.
broadcast [enable | disable] - Enables or disables broadcast storm control.
multicast [enable | disable] - Enables or disables multicast storm control.
unicast [enable | disable] - Enables or disables Unknown unicast traffic
control.
action – Used to configure the action taken when a storm control has been
detected on the switch. The user has two options:
drop - Utilizes the hardware Traffic Control mechanism, which means the
switch's hardware will determine the Packet Storm based on the Threshold
value stated and drop packets until the issue is resolved.
shutdown - Utilizes the switch's software Traffic Control mechanism to
determine the Packet Storm occurring. Once detected, the port will deny all
incoming traffic to the port except STP BPDU packets, which are essential in
keeping the Spanning Tree operational on the switch. If the countdown timer
has expired and yet the Packet Storm continues, the port will be placed in
Rest mode and is no longer operational until (1) auto-recovery after 5 minutes
or (2) the user manually resets the port using the config ports 1 state
disable and config ports 1 state enable command. Choosing this option
obligates the user to configure the time_interval field as well, which will
provide packet count samplings from the switch's chip to determine if a Packet
Storm is occurring.
threshold <value 64-1000000> - The upper threshold at which the specified
traffic control is switched on. The unit will be Kbit/sec in drop mode and
packets/sec in shutdown mode, received by the switch that will trigger the
storm traffic control measures. The default setting is 64.
time_interval - The Interval will set the time between Multicast and Broadcast
packet counts sent from the switch's chip to the Traffic Control function. These
packet counts are the determining factor in deciding when incoming packets
exceed the Threshold value.
countdown - The countdown timer is set to determine the amount of time, in
minutes, that the switch will wait before shutting down the port that is
experiencing a traffic storm. This parameter is only useful for ports configured
as shutdown in the action field of this command and therefore will not operate
for Hardware based Traffic Control implementations.
<minutes 0> - 0 is the default setting for this field and 0 will denote that the
port will never shutdown.
<minutes 5-30> – Select a time from 5 to 30 minutes that the switch will wait
before shutting down. Once this time expires and the port is still experiencing
packet storms, the port will be placed in rest mode and can only be recovered
by the manually recovering option or the auto-recovery option after 5 minutes.
<secs 5-30> - The Interval may be set between 5 and 30 seconds with the
default setting of 5 seconds.
Only Administrator-level users can issue this command.
