Hi Guys,
Help needed, as I am encountered a problem and I would like discuss it with all experts here. As shown in the network diagram attached, some inforamtion about the network as below:
1. All the VLAN gateway is on Core Switch
2. The Core Switch also functioned as a DHCP server
3. Trunk link between Core switch to Access Switch (SW1 & SW2)
4. There is Network Printer / Scanner connecting to SW2 that reside in VLAN 99.
The problem now is that the scanner not able to scan to host A & Host B that in VLAN 10, while host C working just fine. And all host in the network are able to print to the same printer. From the Wireshark packet capture (attached), I suspected the issue is caused by NetBIOS can't go through to different VLAN.
Now I really want to hear some good ideas from you to resolve this and many thanks in advanced.
