10. iSCSI optimization configuration (global)
This example accepts the default settings for aging time and TCP ports that are used in monitored iSCSi sessions. A Compellant
storage array is connected to the port. The policy-iscsi policy map sets the CoS dot1p priority that is used for iSCSI traffic to 6
globally on the switch. By default, iSCSI traffic uses priority 4. The iscsi priority-bits 0x40 command sets the
advertised dot1p priority that is used by iSCSI traffic in application TLVs to 6. Hexadecimal 0x40 is binary 0 1 0 0 0 0 0
0.

11. Verify iSCSI optimization (global)
After you enable iSCSI optimization, the iSCSI application priority TLV parameters are added in the show command output to
verify a PFC configuration.
