Description
• TOS(Hex)—Type of Service. 8 bits in the IP header are
reserved for the service type. They can be divided into 5
subfields: The 3 precedence bits have a value from 0 to 7
and are used to indicate the importance of a datagram.
Default is 0 (higher is better). Bits 3 4 5 represent the
following:
D: requests low delay
T: requests high throughput
R: requests high reliability
• Enable VLAN—If your network administrator has
configured VLAN, check this check box to enable VLAN for
the selected phone. Then enter the VLAN ID for the line port
(voice service) and the VLAN ID for the PC port (data
service). (Get these IDs from your network administrator.)
See "Virtual LANs" on page 327 for information on VLANs.
