User Guidelines
When iSCSI is enabled, the following actions occur:
• The MTU on all ports and port-channels is set to 9216 (jumbo frames are
enabled).
• Flow control is globally enabled, if it is not already enabled.
• iSCSI LLDP monitoring starts to automatically detect Dell EqualLogic
arrays.
When a Dell EqualLogic array is connected to the switch, the switch
automatically detects the array and:
• Enables portfast on the
EqualLogic
port.
• Disables unicast storm control on the
EqualLogic
port.
When the no iscsi enable command is issued, iSCSI resources are released
and the detection of Dell EqualLogic arrays by using LLDP is disabled.
Disabling iSCSI does not remove the MTU, flow control, portfast or storm
control configuration applied as a result of enabling iSCSI.
