Network Configuration Specifics
255
MIVOICE IP PHONE
The MiVoice IP Phones are compatible with CDP and are able to utilize this information for
VLAN and location change discovery, when available. In order to ensure that these work as
expected, it is recommended that ports connected to MiVoice IP Phones and using CDP have
the
cdp timer
and cdp holdtime values left at their default values of 60 and 180 seconds
respectively. If enabled, cdp advertise-v2 should be left in the default state.
LOCATION CHANGE INDICATION
It is possible, within the 3300 ICP System Administration Tool, to highlight when the MiVoice
IP Phones have changed location. This event is logged by the 3300 ICP. An alarm is raised if
the phone moves to an unknown location. The MiVoice IP Phones use the BPDU packets from
the network to provide location information. This is held in a central database on the 3300 ICP.
Any change to this information is an indication that there has been a change in the network
connectivity and this is logged.
The MiVoice IP Phones can read information from either Spanning Tree or Cisco Discovery
Protocol to identify when a phone has changed location. The selection of the relevant
information is made in the Location Change and E911 application associated with the controller.
The location change detection is achieved by enabling Spanning Tree Protocol at the network
port that the IP phone is connected to. The port can still remain in
portfast
since the phone
only has one network connection. One of the three Spanning Tree Protocols should be enabled
at the network port and throughout the network. A description of these settings is covered in
“Port Settings” on page 253.
VLAN/CDP NETWORK PORT CONFIGURATIONS
The MiVoice IP Phones can discover VLAN information through LLDP, DHCP and CDP.
If not manually programmed, the MiVoice IP Phones will continue to use DHCP to locate VLAN
and Priority information if any of the following conditions are true:
•
CDPv2 is not present on the switch
•
CDP is disabled
•
The Auxiliary_VLAN, or Voice VLAN, information is clear, or NULL. (A VLAN ID of ‘0’ is not
a NULL value.)
There are certain network configurations and settings that will allow a single IP-phone to be
used with VMPS, without CDP, although this is not expected to be the normal mode of operation.
This is described under the VMPS section (“VLAN Membership Policy Server (VMPS)” on
page 257).
The MiVoice IP Phones are able to determine the additional VLAN information required to direct
them to a voice VLAN. There are now four potential methods to include information into the IP
phones; these being, in priority order:
1.
Manual Entry at boot time
CAUTION: When the phones are used in Dual Port mode, if VMPS is used, then
CDPv2 must also be enabled.
