HP ProLiant C-GbE - Enabling Ingress Filtering on a Per Port Basis

Configuring the Switch Modules using the Menu-driven Interface
To assign a port a PVID:
1. Highlight Configure Port VLAN ID on the IEEE 802.1Q VLANs
Configuration menu.
2. Press the Enter key. The following screen is displayed.
3. Type the range of port numbers you want to configure in the Configure Port field.
4. Type the PVID for the VLAN member ports you want to configure in the PVID field.
Port VLAN Identifier (PVID) is a classification mechanism that associates a port with a
specific VLAN and is used to make forwarding decisions for untagged packets received
by the port. For example, if Port 2 is assigned a PVID of 3, then all untagged packets
received on Port 2 will be assigned to VLAN 3. This number is generally the same as the
VID# number assigned to the port in the 802.1Q Static VLAN Settings screen.
5. Highlight APPLY.
6. Press the Enter key.
IMPORTANT: To save the configuration settings permanently, you must enter them into NVRAM
using the Save Changes option on the main menu. Refer to the “Saving Changes” section earlier
in this chapter.
Enabling Ingress Filtering on a Per Port Basis
If ingress filtering is enabled for a port, the interconnect switch will examine the VLAN
information in the packet header (if present) and decide whether or not to forward the packet.
The VID should match the PVID of that port, otherwise, that incoming packet is discarded.
If the packet is tagged with VLAN information, the ingress port will first determine if the
ingress port itself is a member of the tagged VLAN.
•
•
If the ingress port is not a member of the tagged VLAN, the packet is dropped.
If the ingress port is a member of the 802.1Q VLAN, the interconnect switch then
determines if the destination port is a member of the 802.1Q VLAN, the packet is
forwarded and the destination port transmits it to its attached network segment.
