LABEL DESCRIPTION
Timeout
(seconds)
The text box displays how long (in seconds) an SNMP request times out. You may
change the timeout by typing a new number in the text box and then clicking the Apply
button.
Group Select the trunk group to which a port belongs.
LACP 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 from 1 second to 30
seconds.
Apply Click Apply to save the changes.

LABEL DESCRIPTION
STP Active Select this check box to activate STP on this port.
Priority Priority is used in determining the root device, root port and designated port. The device
with the highest priority (lowest numeric value) becomes the STP root device. If all
devices have the same priority, the device with the lowest MAC address will then become
the root device. The allowed range is 0 to 255. The lower the numeric value you assign,
the higher the priority for this device.
