name
Description
Name Type the name (such as agg) of this logical interface that can be
referenced by other parts of the configuration. Do not use spaces
or special characters. The maximum length is 15 characters.
Tip: The name cannot be changed once you save the entry. For a
workaround, see “Renaming entries” on page 58.
Type Select 802.3ad Aggregate.
Lacp-rate Select the rate of transmission for the LACP frames (LACPUs)
between FortiWeb and the peer device at the other end of the
trunking cables, either:
•SLOW — Every 30 seconds.
•FAST — Every 1 second.
Note: This must match the setting on the other device. If the rates
do not match, FortiWeb or the other device could mistakenly
believe that the other’s ports have failed, effectively disabling
ports in the trunk.
Algorithm Select the connectivity layers that will be considered when
distributing frames among the aggregated physical ports.
•layer2 — Consider only the MAC address. This results in the
most even distribution of frames, but may be disruptive to TCP
if packets frequently arrive out of order.
•layer2_3 — Consider both the MAC address and IP session.
Queue frames involving the same session to the same port.
This results in slightly less even distribution, and still does not
guarantee perfectly ordered TCP sessions, but does result in
less jitter within the session.
•layer3_4 — Consider both the IP session and TCP connection.
Queue frames involving the same session and connection to
the same port. Distribution is not even, but this does prevent
TCP retransmissions associated with link aggregation.
IP/Netmask Type the IP address/subnet mask associated with the aggregate.
The IP address must be on the same subnet as the network to
which the interface connects. Two network interfaces cannot have
IP addresses on the same subnet.
