If you have problems with the Ethernet connection, you may need to change the network settings. Consult your administrator or the network service provider before you make changes.
1

Press the Settings hard key.

2

If prompted, enter the password to access the Settings menu. You can get the password from your administrator.

3

Scroll down to the Network and service section and tap Network connection > Ethernet.

4

Set the fields as described on the following tabs: Ethernet setup parameters, IPv4 parameters, and IPv6 parameters.

5

After you have set the fields, tap Apply.

The Ethernet setup contains IPv4 and IPv6 settings. See the respective tabs for details.

Table 1. Ethernet setup parameters

Entry

Description

IPv4See the IPv4 parameters tab.
IPv6See the IPv6 parameters tab.

Domain Name

Name of the Domain Name System (DNS) in which the phone resides.

Admin VLAN ID

Auxiliary VLAN of which the phone is a member.

Used only if the phone does not receive an auxiliary VLAN from the switch; otherwise, this value is ignored.

PC VLAN

Allows the phone to inter-operate with third-party switches that don't support a voice VLAN. The Admin VLAN ID option must be set before you can change this option.

Use IEEE 802.1X

Allows the phone to use IEEE 802.1X authentication to gain access to the network.

When enabled, you can see the transaction status and the protocol that the phone is using.

The following table describes the IPv4 related information.

When DHCP is turned off, the IPv4 settings also apply to the Wi-Fi network.

Table 2. IPv4 parameters

Entry

Description

DHCP

Enables or disables DHCP on the phone.

When DHCP is enabled, the DHCP server assigns the phone an IP address. When DHCP is disabled, the administrator must manually assign an IP address to the phone.

IP address

Available only when DHCP is disabled.

When DHCP is disabled, assign an IP address, the subnet mask, and the default router.

Subnet mask

Available only when DHCP is disabled.

When DHCP is disabled, assign the subnet mask.

Gateway

Available only when DHCP is disabled.

When DHCP is disabled, assign a router for the phone to use.

IPv4 DNS address 1

IPv4 DNS address 2

IPv4 DNS address 3

Available only when DHCP is disabled.

Specify the Primary Domain Name System (DNS) server (IPv4 DNS address 1) and optional backup DNS servers (IPv4 DNS address 2 and 3) that the phone uses.

Alternate TFTP

Available only when DHCP is enabled.

Indicates whether the phone is using an alternate TFTP server.

TFTP server 1

Primary Trivial File Transfer Protocol (TFTP) server that the phone uses.

If you are not using DHCP in your network and you want to change this server, you must specify a valid TFTP server address for TFTP Server 1.

If you set the Alternate TFTP option to On, you must specify a valid server address for TFTP Server 1.

If neither the primary TFTP server nor the backup TFTP server is listed in the CTL or ITL file on the phone, you must unlock the file before you can save changes to the TFTP Server 1 option. In this case, the phone deletes the file when you save changes to the TFTP Server 1 option. A new CTL or ITL file downloads from the new TFTP Server 1 address.

When the phone looks for the TFTP server, the phone gives precedence to manually assigned TFTP servers, regardless of the protocol. If your configuration includes both IPv6 and IPv4 TFTP servers, the phone prioritizes the order that it looks for the TFTP server by giving priority to manually assigned IPv6 TFTP servers and IPv4 TFTP servers. The phone looks for the TFTP server in this order:

  1. Any manually assigned IPv4 TFTP servers

  2. Any manually assigned IPv6 servers

  3. DHCP assigned TFTP servers

  4. DHCPv6 assigned TFTP servers

For information about the CTL and ITL files, see the Cisco Unified Communications Manager Security Guide.

TFTP server 2

Optional backup TFTP server that the phone uses if the primary TFTP server is unavailable.

If neither the primary TFTP server nor the backup TFTP server is listed in the CTL or ITL file on the phone, you must unlock either of the files before you can save changes to the TFTP Server 2 option. In this case, the phone deletes either of the files when you save changes to the TFTP Server 2 option. A new CTL or ITL file downloads from the new TFTP Server 2 address.

If you forget to unlock the CTL or ITL file, you can change the TFTP Server 2 address in either file, then erase the old trust list by resetting the security certificate. A new CTL or ITL file downloads from the new TFTP Server 2 address.

When the phone looks for the TFTP server, it gives precedence to manually assigned TFTP servers, regardless of the protocol. If your configuration includes both IPv6 and IPv4 TFTP servers, the phone prioritizes the order that it looks for the TFTP server by giving priority to manually assigned IPv6 TFTP servers and IPv4 TFTP servers. The phone looks for the TFTP server in the following order:

  1. Any manually assigned IPv4 TFTP servers

  2. Any manually assigned IPv6 servers

  3. DHCP assigned TFTP servers

  4. DHCPv6 assigned TFTP servers

For information about the CTL or ITL file, see Cisco Unified Communications Manager Security Guide.

BOOTP server

Indicates whether the phone received the IP address from a BOOTP server rather than from a DHCP server.

DHCP address released

If you wish to remove the phone from the VLAN and release the IP address for reassignment, toggle on this option.

Before IPv6 setup options can be configured on your device, IPv6 must be enabled and configured in Cisco Unified Communication Administration. The following device configuration fields apply to IPv6 configuration:

  • IP Addressing Mode

  • IP Addressing Mode Preference for Signalling

If IPv6 is enabled in the Unified cluster, the default setting for IP addressing mode is IPv4 and IPv6. In this addressing mode, the phone acquires and uses one IPv4 address and one IPv6 address. It can use the IPv4 and the IPv6 address as required for media. The phone uses either the IPv4 or IPv6 address for call control signaling.

For more details about IPv6 deployment, see the IPv6 Deployment Guide for Cisco Collaboration Systems Release 12.x and 14.

The following table describes the IPv6 related information.

Table 3. IPv6 parameters

Entry

Default value

Description

DHCPv6

Yes

Indicates the method that the phone uses to get the IPv6-only address.

When DHCPv6 is enabled, the phone gets the IPv6 address either from DHCPv6 server or from SLAAC by RA sent by the IPv6-enabled router. And if DHCPv6 is disabled, the phone will not have any stateful (from DHCPv6 server) or stateless (from SLAAC) IPv6 address.

IPv6 address

::

Displays the current IPv6 address of the phone or allows the user to enter a new IPv6-only address.

A valid IPv6 address is 128 bits in length, including the subnet prefix. Two address formats are supported:

  • Eight sets of hexadecimal digits separated by colons X:X:X:X:X:X:X:X

  • Compressed format to collapse a single run of consecutive zero groups into a single group represented by a double colon.

If the IP address is assigned with this option, you must also assign the IPv6 prefix length and the default router.

IPv6 prefix length

0

Displays the current prefix length for the subnet or allows the user to enter a new prefix length.

The subnet prefix length is a decimal value from 1 to 128.

IPv6 gateway

::

Displays the default router used by the phone or allows the user to enter a new IPv6-only default router.

IPv6 DNS address 1

::

Displays the primary DNSv6 server used by the phone or allows the user to enter a new server.

IPv6 DNS address 2

::

Displays the secondary DNSv6 server used by the phone or allows the user to set a new secondary DNSv6 server.

IPv6 TFTP server 1

::

Displays the primary IPv6 TFTP server used by the phone or allows the user to set a new primary TFTP server.

IPv6 TFTP server 2

::

(Optional) Displays the secondary IPv6 TFTP server used if the primary IPv6 TFTP server is unavailable or allows the user to set a new secondary TFTP server.

When DHCP is enabled, the phone gets an IP address from the DHCP server automatically. Otherwise, you have to manually configure the settings to get your phone connected to the network.

For procedures for manually configuring Ethernet settings, see Configure Ethernet settings for your phone.
