Setting up vlan

Hi,

Looking at setting up my first vlan look at many websites and YouTube etc but none the wiser,

Equipment
Router Ubiquiti EdgeRouter ER-X
Switch TP-LINK SL-SG2428P
AP Netgear WAX610

I have ER Internet going into Port 1 on switch and port 24 is the AP

I have setup a wireless network in AP using vlan 88

I assume I create a VLAN of 88 in the router and give it an ip and dhcp acesss, but what do I put on the switch to allow vlan 88?

Thanks
