To do...
Enter port
group view
Configure the port link type as
hybrid
Configure current hybrid port(s) to
permit the packets of the specified
protocol-based VLANs to pass
through
Associate the hybrid port(s) with
the specified protocol-based
VLAN
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 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.
A protocol-based VLAN on a hybrid port can process only untagged inbound packets, whereas the
voice VLAN in automatic mode on a hybrid port can process only tagged voice traffic. Therefore, do
not configure a VLAN as both a protocol-based VLAN and a voice VLAN. For more information,
refer to Voice VLAN
After you configure a command on a Layer-2 aggregate interface, the system starts applying the
configuration to the aggregate interface and its aggregation member ports. If the system fails to do
that on the aggregate interface, it stops applying the configuration to the aggregation member ports.
If it fails to do that on an aggregation member port, it simply skips the port and moves to the next
port.
Use the command...
