[DHCP Option 66]
When the DHCP server gives the information of TFTP boot server to DHCP client, DHCP
option code is 66. This option is used to identify a TFTP server when the ‘sname’ field in
the DHCP header has been used for DHCP options.
The following is an example of configuring IP address or domain name for TFTP server
using DHCP option 66.
SWITCH(config)# ip dhcp option format OPTION66_1
SWITCH(dhcp-opt[OPTION66_1])# attr 1 length-hidden variable value ip
10.60.250.16
SWITCH(dhcp-opt[OPTION66_1])# exit
SWITCH(config)# ip dhcp pool test
SWITCH(config-dhcp[test])# option code 66 format OPTION66_1
SWITCH(config)# ip dhcp option format OPTION66_2
SWITCH(dhcp-opt[OPTION66_2])# attr 1 length-hidden variable value
tftp.dasan.com
SWITCH(dhcp-opt[OPTION66_2])# exit
SWITCH(config)# ip dhcp pool test
SWITCH(config-dhcp[test])# option code 66 format OPTION66_2
