vlan testing using etherswitchcfg

hi,

is there anyone who knows how i can test vlan feature using *etherswitchcfg*,
it tried to set and get vlan configuration for chip ar8316 it shows me
right output like

#etherswitchcfg
port0:
        vlangroup: 1
        media: Ethernet 1000baseT <full-duplex>
        status: active
port1:
        vlangroup: 1025
        media: Ethernet autoselect (none)
        status: no carrier
port2:
        vlangroup: 1
        media: Ethernet autoselect (none)
        status: no carrier
port3:
        vlangroup: 1
        media: Ethernet autoselect (none)
        status: no carrier
port4:
        vlangroup: 1
        media: Ethernet autoselect (none)
        status: no carrier
vlangroup0:
        vlan: 0
        members 1t,2t,3t,4t
vlangroup1:
        vlan: 1
        members 2
vlangroup2:
        vlan: 0
        members 0t,1t,3t,4t
vlangroup3:
        vlan: 0
        members 0t,1t,2t,4t
vlangroup4:
        vlan: 0
        members 0t,1t,2t,3t
vlangroup5:
        vlan: 0
        members 0t,1t,2t,3t,4t

but i still dont know how i should test it with its limited commands.i have
used vlan feature on a NetGear switch, i still can find how i can assign
LAN IP to a vlan and use it later...

Plz anyone who knows i can test vlan feature with this.

Thanks
