xStack DGS-3600 Series Layer 3 Gigabit Ethernet Managed Switch CLI Manual

config traffic control
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 Shutdown Forever mode and is no longer
operational until the user manually resets the port using the
config
ports 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 0-255000>
−
The upper threshold at which the specified traffic
control is switched on. The
<value>
is the number of broadcast/multicast/dlf
packets, in packets per second (pps), received by the Switch that will trigger the
storm traffic control measures. The default setting is
131072
.
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.
•
sec 5-30
- The Interval may be set between
5
and
30
seconds with the
default setting of
5
seconds.
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.
•
value 0
- 0 is the default setting for this field and
0
will denote that the
port will never shutdown.
•
value 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 shutdown forever
mode and can only be manually recovered using the config ports
command mentioned previously in this manual.
Restrictions
Only administrator-level and operator-level users can issue this command.
Example usage:
To configure traffic control and enable broadcast storm control system wide:
DGS-3627:5#config traffic control all broadcast enable
Command: config traffic control all broadcast enable
Success.
DGS-3627:5#
