What Is 43 Option Dhcp
The DHCP client sends option code 60 in a DHCPREQUEST to the DHCP server. Change public network to private. When the server receives option 60, it sees the VCI, finds the matching VCI in its own table, and then it returns option 43 with the value (that corresponds to the VCI), thereby relaying vendor-specific information to the correct client. In Option 43, use the IP address of the controller management interface. Note 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. Cisco Aironet 1000, 1500, and 1552 access points use a comma-separated string format for DHCP Option 43.
What Is Dhcp Option 43 For
We basically use DHCP option 43 and option 60 in wireless networks for Access Points and Controllers.- Option 43 helps an Access Point to find out Wireless Controller in Layer 3 Network- As soon as AP boots up it sends DHCP message, this DHCP message is forwarded by Switch or router to the Wireless Contoller.- Basically Whenever we are configuring option 43 on the Cisco Switch we need to provide the IP Address of Wireless Controller.- DHCP option 60 is a string used to identify particular DHCP Server on the Network. If you want to get the IP Address from Particular DHCP Server then you need to configure this DHCP Option 60.- Whatever the name we are using DHCP option 60 in the switch, It should be the same in DHCP Server.
