Appendix G Configuring DHCP Option 43 for Lightweight Access Points
Configuring Option 43 for 1100, 1130, 1200, 1240, and 1300 Series Lightweight Access Points
Step 3
Add the option 60 line using the following syntax:
option 60 ascii “
VCI string
”
For the
VCI string
, use the value from
Table G-1
. The quotation marks must be included.
Step 4
Add the option 43 line using the following syntax:
option 43 hex
<
hex string
>
The
hex string
is assembled by concatenating the TLV values shown below:
Type
+
Length
+
Value
Type
is always
f1(hex)
.
Length
is the number of controller management IP addresses times 4 in hex.
Value
is the IP address of the controller listed sequentially in hex.
For example, suppose that there are two controllers with management interface IP addresses,
10.126.126.2 and 10.127.127.2. The type is
f1(hex)
. The length is
2 * 4 = 8 = 08 (hex)
. The IP addresses
translate to
0a7e7e02
and
0a7f7f02.
Assembling the string then yields
f1080a7e7e020a7f7f02
. The
resulting Cisco IOS command added to the DHCP scope is listed below:
option 43 hex f1080a7e7e020a7f7f02
