The service port is for out of band mgmt =

Looks like you like to use in band mgmt.
Start by removing the IP from the service port (I assume you'd like to use that IP to access the switch).
Here a example from my switch....
set IP for access:
network protocol none
network parms 172.25.25.154 255.255.255.0 172.25.25.254
in case you don't use the default VLAN you'd need to set the VLANID for mgmt. e.g. 100 in my example
network mgmt_vlan 100
