We
use hybrid ports where we need more than one untagged vlan on a port. It is also used for VOIP user ports as a best
practice.
You
need to configure VoIP ports as hybrid ports.
On H3C switches, the voice VLAN uses automatic
mode by default. In this mode, the switch
identifies IP phones by their source MAC addresses OUI field of the phone’s
untagged frames. The switch matches
these Organizational Unique Identifiers (OUIs) to its stored list. The list already includes those for Cisco,
Avaya, 3Com, Siemens, and Polycom phones. You can also add OUI addresses for other
vendors. If the device finds a match, it
automatically assigns the port to the voice VLAN, applies ACL rules to the
port, and assigns the port the correct QoS priority. You can also configure the switch’s voice VLAN
aging time, which determines how long the port is considered part of the VLAN
without receiving frames on the device.
For further information refer to the Access volume and Voice VLAN
chapters of the HP A-Series switch documentation.
When
setting up hybrid ports, set a vlan other than vlan 1 as the interface ip port
and remove vlan 1 from all hybrid ports.
On your trunk ports to core set up as pvid to your new management vlan
number and remove vlan 1 as pvid. For user Voip/PC ports set up as hybrid with
the user data vlan as pvid and voip vlan as tagged. Set all other ports as access ports with a
single untagged vlan.
