5. The IP phone sends a request to the DHCP server and invokes the DHCP process.
The phone displays one of the following messages:
• DHCP: s secs * to program
•
DHCP: s secs VLAN ID = n
where s is the number of seconds that have elapsed after the DHCP process was started.
The phone displays the first message if 802.1Q tagging is off and access to local
programming procedures is not disabled or restricted. The phone displays the second
message if 802.1Q tagging is on and access to local programming procedures is disabled
or restricted. If the first and second message alternate every 2 seconds, 802.1Q tagging is
on. When the phone displays both messages alternately, access to local programming
procedures is not disabled or restricted. Finally, the phone displays the third message if
802.1Q tagging is off and access to local programming procedures is disabled or restricted.
6. The system determines the DHCP protocol , IPv4 or IPv6 protocol, and the applicable
parameters that are enabled.
Important:
IPv6 operation is limited to a specific customer set and not for general use.
Note:
The IPV6STAT parameter overrides both the DHCPSTAT parameter setting and
manual programming. If DHCPSTAT is set to enable DHVPv6, DHCPSTAT is disabled
if IPV6STAT is 0 and disabled. Manual programming overrides DHCPSTAT, therefore
even if DHCPSTAT is set to enable DHCPv4 or DHCPv6, the DoDHCPV4 or
DoDHCPV6 will be set to 0 and disabled if an IP address of the corresponding type
has been manually programmed.
The DHCP server provides the IP addresses for the following hardware:
• The phone
• The HTTP/HTTPS server
• The TN799C or D Control-LAN (C-LAN) circuit pack on the media server
7. Using the list of gateway IP addresses provided by the DHCP server, the phone performs a
router check. The phone cycles through the gateway IP addresses with ARPs or pings until
it receives a response. When the router is located, the router processes the received LLDP
TLVs. Then the HTTP process starts.
8. While the IP phone connects to the HTTP server, the phone displays one of the following
messages:
HTTP: n ipadd
or HTTP: n ipadd * to program
or HTTP: n ipaddProgram
where n is the number of the IP address obtained from the HTTP server and ipadd is the
IP address.
