Configuring Ethernet Ports to Support Cisco IP Phones with Multiple Ports
You might want to use multiple ports to connect the Cisco IP phones if any of the following conditions
apply to your Cisco IP telephony network:
•
•
•
•
IP Addressing
The recommended configuration for using multiple cables to connect IP phones to the Cisco AVVID
network is to use a separate IP subnet and separate VLANs for IP telephony.
Managing the Ethernet Switch Network Module
This section describes how to perform basic management tasks on the Ethernet switch network module
with the Cisco IOS CLI. You might find this information useful when you configure the switch for the
previous scenarios.
The following topics are included:
•
•
You are connecting Cisco IP phones that do not have a second Ethernet port for attaching a PC.
You want to create a physical separation between the voice and data networks.
You want to provide in-line power easily to the IP phones without having to upgrade the data
infrastructure.
You want to limit the number of switches that need Uninterruptible Power Supply (UPS) power.

Purpose
Sets the native VLAN for untagged traffic.
The value of 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.
Configures 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).
Returns to the privileged EXEC mode.
