looking at the picture, If I do the pruning and exclude VLAN 30 from allowed VLAN list but allow every other vlans on Trunk port (g1) on switch B because I don’t have any other VLAN 30 members anywhere in my network, does this affect VLAN 30’s inter-vlan routing and/or internet connection?
In other word, what does the switch do in terms of tagging frames when
Trunks are used to carry multiple vlans which isn't the case above.... Why don't you make a port in SW2 a layer 3 port and assign an IP address in the same range as vlan 10? (considering that we are dealing with L3 switches..)
If you can't do that your second option is to create a vlan 10 in SW2 and assign the interface that connects to SW1 to vlan 10.
They are L2 switches. In regards to the second option, actually those VLANs are wireless VLANs created on a WLC, not the wired ones, And what connect to SW1 ports are actually lightweight APs!
Btw seems you are right. There is no need of trunking if there is just one single vlan on SW1. And seems I can configure g1 and g2 as Access Ports and put them in VLAN 100 which is my wired VLAN for connecting APs to the management interface of the WLC.
