By default the ports are in 4:1 over subscription mode.You can turn it off for the entire blade in which only ports 1,5,9 and 13 can be used, or for a single port group.

For the entire blade the command is:

no hw-module switch (#) slot (#) oversubscription

For a group:

"no hw-module switch (#) slot (#) oversubscription port-group (#)

Below is a link to the supporting documentation:

Hi,

ten 1/1/5

channel group 1

That shouldn't be an issue.
