Chapter 5. IBM System Networking RackSwitch implementation 169
Protocol-based VLANs
This feature is not part of our reference architecture implementation. However, for
completeness, we provide a summary of commands used for configuration and verification in
this section.
For more information about the protocols-based VLANs concept, see Chapter 2, “IBM
System Networking Switch 10Gb Ethernet switch features” on page 51.
Consider the following guidelines when you configure protocol-based VLANs:
򐂰 Each port can support up to 16 VLAN protocols.
򐂰 The RackSwitch G8264 switch can support up to 16 protocols simultaneously.
򐂰 Each PVLAN must have at least one port assigned before it can be activated.
򐂰 The same port within a port-based VLAN can belong to multiple PVLANs.
򐂰 An untagged port can be a member of multiple PVLANs.
򐂰 A port cannot be a member of different VLANs with the same protocol association.
Run the following command to configure protocol-based VLAN for a selected VLAN. Run the
commands at the VLAN level to configure the frame type and the Ethernet type for the
selected protocol.
protocol-vlan <1-8> frame-type {ether2|llc|snap} <Ethernet type>
The Ethernet type is a 4-digit (16 bit) hex code, such as 0080 (IPv4).
Run protocol-vlan <1-8> protocol <protocol type> at the VLAN level to select a
predefined protocol. The predefined protocols include:
򐂰 decEther2: DEC Local Area Transport
򐂰 ipv4Ether2: Internet IP (IPv4)
򐂰 ipv6Ether2: IPv6
򐂰 ipx802.2: Novell IPX 802.2
򐂰 ipx802.3: Novell IPX 802.3
򐂰 ipxEther2: Novell IPX
򐂰 ipxSnap: Novell IPX SNAP
򐂰 netbios: NetBIOS 802.2
򐂰 rarpEther2: Reverse ARP
򐂰 sna802.2: SNA 802.2
򐂰 snaEther2: IBM SNA Service on Ethernet
򐂰 vinesEther2: Banyan VINES
򐂰 xnsEther2: XNS Compatibility
Run protocol-vlan <1-8> priority <0-7> at the VLAN level to configure the priority value
for this PVLAN.
Run [no] protocol-vlan <1-8> member <port alias or number> at the VLAN level to add or
remove a port to the selected PVLAN.
Run [no] protocol-vlan <1-8> tag-pvlan <port alias or number> at the VLAN level to
define a port that is tagged by the selected protocol on this VLAN.
Run [no] protocol-vlan <1-8> enable at the VLAN level to enable/disable the selected
protocol on the VLAN.
Important: This feature is supported only on RackSwitch G8264.
