Configure the following on an IR8x9:
ip dhcp pool ic3000_pool2
network 172.27.88.0 255.255.255.128
dns-server 173.36.131.10
option 43 ascii 5A;K4;B2;I172.27.88.63;J9125
option 42 ip 171.70.168.183
default-router 172.27.88.1
lease 0 0 2
Please make note of Option 43 usage:
-
If you have a DHCP server, use the “same” PNP discovery option string that we use for regular IOS routers Option 43 ascii
“5A;K4;B2;I172.27.88.63;J9125" (IGMA will use port 9121 as default. IoT FND IP is 172.27.88.63)
-
If you wish to use a different port provide the following configuration:
option 43 ascii “5A;K4;B2;I192.168.10.6;J9125;W9128"
On a regular Linux server running DHCP, use the following instructions:
cat /etc/dhcp/dhcpd.conf
subnet 10.10.100.0 netmask 255.255.255.0 {
option routers 10.10.100.1;
range 10.10.10.100 10.10.10.199;
option domain-name-servers 10.10.100.1;
option domain-name "test1.dom";
option vendor-encapsulated-options "5A;K4;B2;I10.48.43.227;J9125";
}
In the above example for option 43, the following describes the options:
-
5A;K4;B2;I172.27.88.63;J9125
-
5 – DHCP type code 5
-
A – Active feature operation code
-
; - Delimiter
-
K4 – HTTP transport protocol
-
B2 – PnP server /FND IP address type is IPv4
-
J9125 - port number
