"Not yet, but this problem is on to-do list and will be fixed in version 1.6."
you can try parse hosts data
http://192.168.88.1/!dhost.b
with some script.

Is there possibility to get hosts/port list from snmp ?

I could only find it on web:
curl -u admin:pass --digest 'http://192.168.88.1/!dhost.b'
and parsing it with Perl

Perl modules can't get this info from web, because, there is weird problem with authentication,
same with wget :\

you could try to reboot it from cron

curl -s -m 1 -D - -u admin:password--digest "192.168.ip.ip/reboot" > /dev/null

...
"rebooting the switch (via the gui) does not clear this"
so that's problem
