Rev 1.6.2 5.1.1.2 Returning to the Non-Split Mode  To return to the non-split mode: Step 1. Log in as admin. Step 2. Enter config mode. Run: switch > enable switch # configure terminal Step 3. Shut down all of the split ports. Run: switch (config interface ethernet 1/4/4) # shutdown switch (config interface ethernet 1/4/4) # exit switch (config) # interface ethernet 1/4/3 switch (config interface ethernet 1/4/3) # shutdown switch (config interface ethernet 1/4/3) # exit switch (config) # interface ethernet 1/4/2 switch (config interface ethernet 1/4/2) # shutdown switch (config interface ethernet 1/4/2) # exit switch (config) # interface ethernet 1/4/1 switch (config interface ethernet 1/4/1) # shutdown Step 4. From the first member of the split (1/4/1), change the module-type back to QSFP. Run: switch (config interface ethernet 1/4/1) # module-type qsfp The module-type can be changed only from the first member of the split and not from the interface that was split. Step 5.

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:
switch > enable
switch # configure terminal
switch (config interface ethernet 1/4/4) # shutdown
switch (config interface ethernet 1/4/4) # exit
switch (config) # interface ethernet 1/4/3
switch (config interface ethernet 1/4/3) # shutdown
switch (config interface ethernet 1/4/3) # exit
switch (config) # interface ethernet 1/4/2
switch (config interface ethernet 1/4/2) # shutdown
switch (config interface ethernet 1/4/2) # exit
switch (config) # interface ethernet 1/4/1
switch (config interface ethernet 1/4/1) # shutdown
switch (config interface ethernet 1/4/1) # module-type qsfp
The module-type can be changed
only
from the first member of the split and
not
from
the interface that was split.
switch > enable
switch # configure terminal
