iSCSI CoS and Priority Flow Control/Enhanced Transmission Selection Interactions When manually or automatically enabling the classification of iSCSI flows on PC80xx/PCM8024-k/PC81xx series switches, enabling iSCSI CoS is not recommended unless required as follows. When using manual configuration of the switch or auto-configuration via DCBX, the iSCSI packets are classified based on the user priority present in the VLAN tag and, in this case, enabling iSCSI CoS classification via the iSCSI command set provides no benefit. The only case for enabling iSCSI CoS prioritization is when using PC81xx-series switches to originate iSCSI configuration information via DCBX. In this case, enabling iSCSI CoS classification configures the PC81xx switch to generate the iSCSI TLV via DCBX in support of configuring directly connected storage and initiator devices. Since EQL iSCSI devices require ETS settings to function correctly with DCBx, the PC80xx and M8024-k series PowerConnect switches (which do not support ETS) should disable DCB when EQL devices are connected. PC8100 series switches support both ETS and DCBx and support DCB configuration in conjunction with EQL devices. Configuring iSCSI Optimization 401
