• iSCSI LLDP monitoring starts to automatically detect EqualLogic arrays.
The following message displays when you enable iSCSI on a switch and describes the conguration changes that are automatically
performed:
%STKUNIT0-M:CP %IFMGR-5-IFM_ISCSI_ENABLE: iSCSI has been enabled causing flow
control to be enabled on all interfaces. EQL detection and enabling iscsi
profile-compellent on an interface may cause some automatic configurations to
occur like jumbo frames on all ports and no storm control and spanning tree
port-fast on the port of detection.
