Configuration file is not downloading in extreme switch when auto provision is enabled through dhcp

[akshay]

I have configured the dhcp server with option 43 code 101 with a script name "boot_file.xsf". After factory reset whenever the switch is contacting the dhcp server, it receives only ip address but not the boot_file.xsf file from the tftp server which I have given in option 43.
I am using Extreme X620 switch.

I have already used option 100 but still it is not working.

my dhcp configuration look like this

option space SWITCH;
option SWITCH.tftp-server-ip code 100 = ip-address;
option SWITCH.config-file-name code 101 = text;

class "X620" {
match if option vendor-class-identifier = "X620-16p";
vendor-option-space SWITCH;
option SWITCH.tftp-server-ip 10.1.1.1;
option SWITCH.config-file-name "boot_file.xsf";
}

You will need to code option 100 as well or use a URL format for option 101 like below.

tftp://10.10.10.1/exos/summitX-22.5.1.7.xos
