User Guidelines
This command modifies the running config to enable flow control on all
interfaces.
Monitoring for EqualLogic Storage arrays via LLDP is also enabled by this
command. Upon detection of an EQL array, the specific interface involved
will have spanning-tree portfast enabled and unicast storm control disabled.
These changes appear in the running config. Disabling iSCSI Optimization
does not disable flow control, portfast or storm control configuration applied
as a result of enabling iSCSI Optimization.
Enabling iSCSI will enable the sending of the DCBX Application Priority
TLV to a port with the following parameters when the following conditions
are met:
