Configuring A Protocol-Based Vlan - H3C S7500E Series Operation Manual

Operation Manual – VLAN
H3C S7500E Series Ethernet Switches
In this approach, inbound packets are assigned with different VLAN IDs based on their
protocol type and encapsulation format. The protocols that can be used to categorize
VLANs include: IP, IPX, and AppleTalk (AT). The encapsulation formats include:
Ethernet II, 802.3 raw, 802.2 LLC, and 802.2 SNAP.
A protocol-based VLAN can be defined by a protocol template, which is determined by
encapsulation format and protocol type. A port can be associated to multiple protocol
templates. An untagged packet (that is, packet carrying no VLAN tag) reaching a port
associated with a protocol-based VLAN will be processed as follows.
If the packet matches a protocol template, the packet will be tagged with the VLAN
ID of the protocol-based VLAN defined by the protocol template.
If the packet matches no protocol template, the packet will be tagged with the
default VLAN ID of the port.
A tagged packet (that is, a packet carrying VLAN tags) reaching the port is processed in
the same way as that of port-based VLAN.
If the port is configured to permit packets with the VLAN tag, the packet is
forwarded.
If the port is configured to deny packets with the VLAN tag, the packet is dropped.
This feature is mainly used to bind the service type with VLAN for ease of management
and maintenance.

1.5.2 Configuring a Protocol-Based VLAN

Follow these steps to configure a protocol-based VLAN:
Enter system view
Enter VLAN view
Configure the protocol
based VLAN and specify
the protocol template
Exit the VLAN view
To do...
