(For more information about these parameters, see the “Network Parameters” section on page 8-2.) See Table 3-1for information about which VLAN-related parameters and bits to configure depending on your network environment.

OpFlags parameter:

Bit 4—Enable the use of user-specified voice VLAN ID

Bit 5—Disable VLAN IP encapsulation
