Hi longlanh,
assuming your clients are normal PCs or laptops and not servers and you are having problems with vlan 5, you should have the switch ports with clients as untagged.
As these devices typically don't support and tag their traffic. With your current setup they most likely send the traffic without any vlan tags and it gets placed into vlan 1:
vlan 1
name "DEFAULT_VLAN"
untagged 1-48,A1-A2,A4,Trk1
vlan 5
name "Clients"
tagged 1,Trk1
So changing port 1 as untagged in vlan 5 should fix this issue.
HTH,
