LABEL DESCRIPTION EXAMPLE
Broadcast Storm
Control Enable Broadcast Storm Control to reduce broadcast traffic coming
into or going out of this port. Broadcast Storm Control includes
multicast packets. Use the Threshold field to limit the number of
broadcast frames that can be:
Stored in a port’s buffer or
Sent out from the port.
Broadcast frames that arrive within the monitor interval specified in the
Switch Setup screen but after the buffer is full are discarded.
Threshold Select the number of frames allowed in the Threshold drop-down list
box. If you wish your network to receive or broadcast a lot of broadcast
traffic then choose a larger number. To reduce broadcast traffic coming
into or going out of your network, choose a smaller number.
128
Direction Select Incoming to control how many broadcast frames the port can
store in the switch buffer and select Outgoing to control how many
frames the port will send out.

Link Aggregate
Control Protocol The ES-3024 supports the link aggregation IEEE802.3ad standard.
This standard describes the Link Aggregate Control Protocol (LACP),
which is a protocol that is used to dynamically create and manage
trunk groups. The standard provides link identification, status
monitoring and synchronization across links.
Timeout Timeout is the time interval between the individual port exchanges of
LACP packets in order to check that the peer port in the trunk group is
still up. If a port does not respond after three tries, then it is deemed to
be “down” and is removed from the trunk. Set a short timeout (one
second) for busy trunked links to ensure that disabled ports are
removed from the trunk group as soon as possible.
Select either 1 second or 30 seconds.
802.1x Select this checkbox to permit 802.1x authentication on this port. You
must first allow 802.1x authentication on the switch (see Switch Setup
screen) before configuring it on each port.
Reauthentication Specify if a subscriber has to periodically re-enter his or her username
and password to stay connected to the port.
On
Reauthentication
Timer
Specify how often a client has to re-enter his or her username and
password to stay connected to the port. 3600
