switch# config t
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# no rate-mode oversubscription-limit module 2
Step 5 Bring up the ports that you shut down in step 2, and display their status to confirm that they are no longer
shut down.
switch(config)# interface fc2/1-2, fc2/4-5, fc2/8-38, fc2/43-48
switch(config-if)# no shutdown
switch(config-if)# end

switch# copy running-config startup-config
Enabling Restrictions on Oversubscription Ratios
Prerequisites
• You must enable restrictions on oversubscription ratios before you can downgrade modules to a
previous release.
• Before enabling restrictions on oversubscription ratios, ensure that you have explicitly configured
shared ports to out-of-service mode.
