• in case of split-2, shut down the current interface only
• in case of split-4, shut down the current interface and the other interface
Step 2.
Split the ports as desired. Run:
Step 3. The following warning will be displayed: the following interfaces will be unmapped:
1/4 1/1
.
Choose
Yes when prompted Type 'yes' to confirm split
The <ports> field in the warning refers to the affected ports from splitting port <inf> in the
applied command.
5.1.1.2 Unsplitting a Split Port
 To unsplit a split port:
Step 1. Shut down all of the split ports. Run:
Step 2. From the first member of the split (1/4/1), change the module-type back to QSFP. Run:
The following warning will be displayed:
The following interfaces will be unmapped: 1/4/1 1/
4/2 1/4/3 1/4/4
.
Step 3. Type yes when prompted Type 'yes' to confirm unsplit .
switch (config) # interface ethernet 1/1
switch (config interface ethernet 1/1) # shutdown
switch (config interface ethernet 1/1) # exit
switch (config) # interface ethernet 1/4
switch (config interface ethernet 1/4) # shutdown
switch (config interface ethernet 1/4) # module-type qsfp-split-4
switch (config interface ethernet 1/4) #
Please beware that splitting a port into 4 prevents you from accessing the splittable port,
and additional one. For example, in the procedure above, ports 3 and 4 become unacces-
sible.
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.
