286 Appendix I Enhanced DHCP option commands
N0115791
Use this command to assign VoIP server information to Nortel’s i2004 VoIP telephones.
This command sets DHCP option 128.
The following example commands set the BCM50a Integrated Router to assign
information for two VoIP servers. The first command sets it to assign the first VoIP
server’s IP address (11.12.13.7), port number (7001) and retry count (three) to Nortel’s
i2004 VoIP telephones.
ip dhcp enif0 server voipserver 1 11.12.13.7 7001 3
This next command sets the BCM50a Integrated Router to assign the second VoIP
server’s IP address (11.12.13.8), port number (7002) and retry count (2) to Nortel’s i2004
VoIP telephones.
ip dhcp enif0 server voipserver 2 11.12.13.8 7002 2
The BCM50a Integrated Router sends the VoIP server information for both servers when
it receives a DHCP request from Nortel’s i2004 VoIP telephones.
VLAN ID assignment
Syntax:
ip dhcp <interface> server vlanid [none | <vlan id1> [<vlan id2> <vlan
id10>]]
where:
Use this command to assign VLAN IDs to IP Telephone 2004.
[port (1~65535)]
This is the VoIP server’s listening port (1~65535).
[retry count (0~255)]
This sets the number of times (0-255) the i2004 can
attempt to connect to this VoIP server (without a response),
before trying to connect to the other server.
<interface>
Specify an interface on the device. Currently you can use
this command with the LAN Ethernet interface (enif0).
[none | <vlan id1>
[<vlan id2> <vlan
id10>]]
Virtual LANs use identifiers called VLAN IDs. This specifies
the VLAN IDs (if any) to assign to the VoIP telephones. You
can specify up to 10 VLAN IDs. Each VLAN ID must be a
number from 0 to 4095.
Use “none” if you do not want the DHCP server to
automatically assign VLAN IDs to the VoIP telephones.
