CAUTION:
• Do not configure both the
dsap-id
and
ssap-id
arguments in the protocol-vlan command as 0xe0 or
0xff when configuring the user-defined template for llc encapsulation. Otherwise, the encapsulation
format of the matching packets will be the same as that of the ipx llc or ipx raw packets, respectively.
When either of the
dsap-id
and
ssap-id
arguments is configured, the system assigns aa to the other
argument.
• When you use the mode keyword to configure a user-defined protocol template, do not set
etype-id
in
ethernetii etype
etype-id
to 0x0800, 0x8137, 0x809b, or 0x86dd. Otherwise, the encapsulation
format of the matching packets will be the same as that of the IPv4, IPX, AppleTalk, and IPv6 packets,
respectively.
Description
Use the protocol-vlan command to configure the VLAN as a protocol based VLAN and configure the
protocol template for the VLAN.
Use the undo protocol-vlan command to remove the configured protocol template.
By default, no VLAN is bound to any protocol template.
Related commands: display protocol-vlan vlan.
NOTE:
Do not configure a VLAN as both a protocol-based VLAN and a voice VLAN.
Examples
# Configure VLAN 3 as an IPv4 based VLAN.
<Sysname> system-view
[Sysname] vlan 3
[Sysname-vlan3] protocol-vlan ipv4
CAUTION:
IP uses ARP for address resolution in Ethernet. To prevent communication failure, confi
ure the IP and ARP
templates in the same VLAN and associate them with the same port.
# Create an ARP protocol template for VLAN 3 (ARP code is 0x0806) to make VLAN 3 transmit ARP
packets.
• To use Ethernet encapsulation, use the command:
[Sysname-vlan3] protocol-vlan mode ethernetii etype 0806
• To use 802.3 encapsulation, use the command:
[Sysname-vlan3] protocol-vlan mode snap etype 0806
IP subnet-based VLAN configuration commands
display ip-subnet-vlan interface
Syntax
display ip-subnet-vlan interface { interface-list | all } [ | { begin | exclude | include }
