5.2 Link Aggregation Group (LAG)
Link Aggregation protocol describes a network operation in which several same speed links are
combined into a single logical entity with the accumulated bandwidth of the originating ports.
LAG groups exchange Lag Aggregation Control Protocol (LACP) packets in order to align the
functionality between both endpoints of the LAG. To equally send traffic on all LAG links, the
switch uses a hash function which can use a set of attributes as key to the hash function.
As many as 16 physical ports can be aggregated on a single port-channel.
5.2.1 Configuring Static Link Aggregation Group (LAG)
 To configure a static LAG:
Step 1. Log in as admin.
Step 2. Enter config mode. Run:
Step 3. Create a port-channel entity. Run:
Step 4. Change back to config mode.
Step 5. Enable LACP in the switch. Run:
Step 6. Add a physical port to the port-channel. Run:
5.2.2 Configuring Link Aggregation Control Protocol (LACP)
 To configure LACP:
Step 1. Log in as admin.
Step 2. Enter config mode. Run:
Step 3. Create a port-channel entity. Run:
switch > enable
switch # configure terminal
switch (config) # interface port-channel 1
switch (config interface port-channel 1) #
switch (config interface port-channel 1) # exit
switch (config) #
switch (config) # lacp
switch (config) #
switch (config interface ethernet 1/4) # channel-group 1 mode on
switch (config interface ethernet 1/4) #
If the physical port is operationally up, this port will be an active member of the aggre-
gation. Consequently, it will be able to convey traffic.
switch > enable
switch # configure terminal
switch (config) # interface port-channel 1
switch (config interface port-channel 1) #
