awareness use the no form of this command.

User Guidelines
This command enables iSCSI monitoring for the establishment of iSCSI
sessions on TCP ports 960 and 3260. Sessions that are established (using a
PLOGI) on these ports are displayed in the iSCSI session table. In addition,
this command modifies the running config to globally set the mtu size to
9216 on all interfaces and port-channels, and enables 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 does not remove
the mtu, flow control, portfast or storm control configuration applied as a
result of enabling iscsi.
