Reference Guide

iSCSI trac uses priority 4. The iscsi priority-bits 0x40 command sets the advertised dot1p priority used by iSCSI trac 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
conguration.
