Figure 23: Multiple VLAN Per-port Binding Modes
Ingress VLAN Security
Ingress VLAN security uses VLAN tagging information to drop packets which do not have the
appropriate tagging. The accept or drop action depends on the binding mode of the ingress
port.
Figure notes:
1. Bind to All
- Any VLAN in the range of 1 to 3,071 will be allowed access through this port
- Intended mainly for easy backbone link
2. Static Binding
- You manually specify the list of VLAN IDs to be bound to the port, up to 3,071 VLANs
- Default mode for every port
- Only VLAN 9, and any other VLANs statically configured on the port will be allowed to
access this port
3. Bind to Configured
- The VLAN table of the port will support all the Static VLAN entries and all the ports'
VLAN IDs (PVIDs) present in the switch
- VLANs 1,3,5,9,10 coming from the bus will be allowed access through this port
- All the ports in Bound to Configured mode will support the same list of VLANs
