How to correctly configure individual access to cluster Unit with Out of band interface

[Phinestra200]

we have a 300E a-p cluster in 5.6.4. we're triying to configure access to cluster through a Virtual IP address and both individual IP of each cluster unit.

[ul]

the management subnet is 10.10.10.0/26

the switch IP which the 3 ports are connected (mgmt,port2(unit1) port2(unit2))  is 10.10.10.10/26

we reserved the IP 10.10.10.1/26 for "mgmt" port for the access to the cluster.

we reserved port2 for dedicated access for each unit with IP 10.10.10.2/26 ( unit 1) and 10.10.10.3/26 for unit 2.[/ul]

in config sys ha,  we've enabled the option  "management interface reservation" and set the default gateway to 10.10.10.1 (the IP of the mgmt port). IN CLI (extract from full config) set ha-mgmt-status enable     config ha-mgmt-interfaces         edit 1             set interface "port2"             set dst 0.0.0.0 0.0.0.0             set gateway 10.10.10.1             set gateway6 ::         next     end we are unable to access the second unit, only the master O.o  is it a correct way to configure an individual cluster unit access?

i've followed the online help but the didn't specify what the default gateway refered to....

thanks in advance for any help.   Phi.
