Only statically mapped iSLB initiator configuration is distributed throughout the fabric

distributed.
Dynamic load balancing of iSLB initiators is available using iSCSI login redirect and VRRP.

The maximum number of iSLB and iSCSI initiators supported in a fabric is 2000.
The maximum number of iSLB and iSCSI sessions supported by an IPS port in either transparent or
proxy initiator mode is 500.
The maximum number of iSLBinitiators supported in a fabric is 2000.
The maximum number of iSLB sessions per IPS port in either transparent or proxy initiator mode is
500.
The maximum number of switches in a fabric that can have iSLB with CFS distribution enabled is
four.
No more than 200 new iSLB initiators can be added to the pending configuration. Before adding
more initiators, you must commit the configuration.
You cannot disable iSCSI if you have more than 200 iSLB initiators in the running configuration.
Reduce the number of iSLB initiators to fewer than 200 before disabling iSCSI.
iSLB can be used without CFS distribution but if iSLB auto-zone feature is used, traffic is disrupted
when any zoneset is activated.
