Example System Overview
IP Office Configuration
The table below details the configuration for IP Office. Additional
configuration is not required by IP Office in support of 802.1 tagging.
IP Phone- Configuration
In the example below, the IP phone was configured
with fixed IP addressing.
VLAN Switch Configuration
The table below summaries the HP configuration for ports and
VLANs.
The PC –Configuration
Shown below is the IP configuration of the PC1; no
option in support of 802.1p or 802.1q is enabled on
the PC.
Summary
From the port on which the PC and IP phone reside, you can receive two types of Ethernet frame (i.e. sent from Phone or
PC):
1. Tagged packets are sent by IP Phone.
2. Untagged packets are sent by PC.
When an untagged packet is sent by the PC attached to the IP Phone port, it will be propagated only to VLAN 101. This is
because when we added the port 3 to VLAN 101 the Mode option was specified as untagged. While for the other VLAN
(101) the option Tagged was selected for port 3 in VLAN 101. Tagged packets will thereby go to VLAN 100 while the
untagged will go to 101.
When a packet originates from an IP Phone it is tagged. Since the option 'untagged' is selected for port 5 in VLAN 100,
the 802.1 tag is removed before the switch forwards the packet to this port. Similarly, when an untagged packet is
originated and sent by the IP Office, the switch will tag the packet before forwarding LAN port 3.
