Hi,
the range of vlan 80 is 10.101.108.129-158, and the range of vlan 120 is 10.101.108.129-190. So the range of host addresses is overlapping. It's early morning here in germany, hope i'm right...:-)

int vlan 80
ip add 10.101.108.129 255.255.255.224
The above vlan is for IPs from .129-.159
10.101.108.129 - Network ID
10.101.108.130 - First Host
10.101.108.158 - Last Host
10.101.108.159 - Broadcast ID
--------
int vlan 120
ip add 10.101.108.161 255.255.255.192
The above vlan is for IPs from .129-.191
10.101.108.129 - Network ID
10.101.108.130 - First Host
10.101.108.190 - Last Host
10.101.108.191 - Broadcast ID
This explains the overlap - IPs from .129-.159 are a part of VLAN 80 already.
You may use the network 10.101.108.192/26 for VLAN 120.
