Issue 6.0 NEC SL1100
9 - 24 IP Multiline Station (SIP)
802.1Q allows a change in the Ethernet Type value in the Ethernet header
tagging the Protocol ID 0x8100, identifying this frame as an 802.1Q frame.
This inserts additional bytes into the frame that composes the VLAN ID (valid
IDs = 1 ~ 4094).
802.1P allows you to prioritize the VLAN using a 3-bit priority field in the
802.1Q header. Valid VLAN priority assignments are 0 ~7. A tag of 0 is
treated as normal data traffic giving no priority. Under normal circumstances
the higher the tag numbers, the higher the priority. However this is left up to
the network administrator as they could set the exact opposite where the lower
tag numbers have a higher priority.
Tagging Voice and Data Packets
Built into the IP phones is a 2 port 10/100 manageable data switch allowing for
a PC connection on the back of the IP phone. This built in data switch also
supports 802.1Q and 802.1P VLAN tagging capabilities.
The following procedures describe two methods for tagging the voice packets
and the data packets separately, using the PC, or using the phone keypad.
