Configuring Ethernet Ports to Support IP Phones and a Daisy-Chained Workstation
This configuration approach must address two key considerations:
•
•
The following procedure shows how to automatically configure Cisco IP phones
to send voice and data traffic on the same VLAN.
Task
Step 1
Set up switch port to configure IP phone on
the same VLAN as the access VLAN.
Enter global configuration mode.
Enter the interface configuration mode and
the port to be configured (for example,
interface fa5/1
Set the native VLAN for untagged traffic.
vlan-id represents the ID of the VLAN that
is sending and receiving untagged traffic on
the port. Valid IDs are from 1 to 1001.
Leading zeroes are not accepted.
Configure the Cisco IP Phone to send voice
traffic with higher priority (CoS=5 on
802.1Q tag) on the access VLAN. Data
traffic (from an attached PC) is sent
untagged for lower priority (port
default=0).
Return to the privileged EXEC mode.
Step 2
Verify the switch port configuration and
save.
Verify the port configuration you just
entered.
Save the current configuration in Flash
memory.

Network managers should ensure that existing subnets have enough available
IP addresses for the new Cisco IP phones, each of which requires a unique
IP address.
Administering a network with a mix of IP phones and workstations on the
same subnet might pose a challenge.
