Configuring DHCP Option 43 and DHCP Option 60
This section contains a DHCP Option 43 configuration example on a Windows 2003 Enterprise DHCP server for use with
Cisco wireless access points. For other DHCP server implementations, consult the product documentation for
configuring DHCP Option 43.
Cisco wireless access points. For other DHCP server implementations, consult the product documentation for
configuring DHCP Option 43.
With DHCP Option 43, use the IP address of the controller management interface.
The Cisco IW3702 access point uses the type-length-value (TLV) format for DHCP Option 43. The TLV block format is:
—
Type: 0xf1 (decimal 241)
—
Length: Number of controller IP addresses * 4
—
Value: List of Cisco Wireless LAN Controller management interfaces
To configure DHCP Option 43 in the embedded Cisco IOS DHCP server:
1.
Enter configuration mode at the Cisco IOS CLI.
2.
Create the DHCP pool, including the necessary parameters such as default router and name server.
Example DHCP scope commands:
ip dhcp pool
pool_name
network
IP_network netmask
default-router
default_router
dns-server
DNS_Server
where,
—
pool_name is the name of the DHCP pool (for example, AP3702).
—
IP_network is the network IP address where the controller resides (for example, 10.0.15.1).
—
netmask is the subnet mask (for example, 255.255.255.0).
—
default_router is the IP address of the default router (for example,10.0.0.1).
—
DNS_Server is the IP address of the DNS server (for example, 10.0.10.2).
3.
Add the option 60 line using the following syntax:
option 60 ascii
VCI_string
where,
—
VCI_string = “Cisco AP iw3702”
Notes:
DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a separate
DHCP pool for each access point type.
DHCP pool for each access point type.
DHCP servers must be programmed to return the option based on the DHCP Vendor Class Identifier
(VCI) string of the access point (DHCP Option 60). The VCI string for the access point is:
(VCI) string of the access point (DHCP Option 60). The VCI string for the access point is:
Cisco AP iw370s
If you ordered an access point with the Service Provider Option (AIR-OPT60-DHCP) selected in the
ordering tool, the VCI string for the access point contains -ServiceProvider. For example, an access
point with this option returns this VCI string:
ordering tool, the VCI string for the access point contains -ServiceProvider. For example, an access
point with this option returns this VCI string:
Cisco AP iw3702-ServiceProvider
