The standard also provides provisions for
a quality of service prioritization scheme
commonly known as IEEE 802.1p and defines
the Generic Attribute Registration Protocol.
VLAN ID Specifies the VLAN to which the Ethernet
frame belongs. A 12-bit field specifying the
VLAN to which the Ethernet frame belongs.
The hexadecimal values of 0x000 and 0xFFF
are reserved. All other values may be used as
VLAN identifiers, allowing up to 4094 VLANs.
The reserved value 0x000 indicates that the
frame does not belong to any VLAN; in this
case, the 802.1Q tag specifies only a priority
and is referred to as a priority tag. On bridges,
VLAN 1 (the default VLAN ID) is often reserved
for a management VLAN; this is vendor
specific.
VLAN Priority Sets the frame priority level. Otherwise known
as Priority Code Point (PCP), VLAN Priority is
a 3-bit field which refers to the IEEE 802.1p
priority. It indicates the frame priority level.
Values are from 0 (lowest) to 7 (highest).
These values can be used to prioritize different
classes of traffic (voice, video, data, etc).
SIP (6-bit DSCP
value)
Can provide quality of service if the DSCP
protocol is supported on your network. Can be
specified independently for SIP control packets
versus RTP audio packets.
RTP (6-bit DSCP
value)
DHCP Timeout
(seconds)
This setting is only visible when the DHCP
Protocol is selected.
The DHCP timeout is the length of time
following a request from an 8180 to the
DHCP server that the 8180 will wait before
assuming the server is not available. After such
time, the 8180 will use its default address of
192.168.1.111
Default is 60 seconds.
