User Guidelines
This command modifies the running config to enable flow control on all
interfaces.
Monitoring for EqualLogic Storage arrays via LLDP is 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.
On the N4000 switches, enabling iSCSI will locally generate a DCBX
Application Priority TLV with the following parameters when the following
conditions are met:
• DCBX is enabled
• CoS Queuing is enabled on the port using VPT ( iscsi cos enable )
The Application Priority TLV sent will contain the following information in
addition to any other information contained in the TLV:
AE Selector = 1
AE Protocol = 3260
