Hi,
Trying to auto install Cat9300 via iPXE, using the below steps.
Ref:
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/prog/configuration/169/b_169_programmability_cg/ipxe.html
DHCP file used:
subnet 20.1.1.0 netmask 255.255.255.0 {
range 20.1.1.100 20.1.1.150;
host Switch {
fixed-address 20.1.1.105;
hardware ethernet 68:CA:E4:A1:57:80;
if exists user-class and option user-class = 04:68:50:58:45 {
filename "http://20.1.1.88/cat9k_iosxe.16.06.05.SPA.bin" ;
}
#option bootfile-name "http://20.1.1.88/sample_python_2.py";
}
}
DHCP server receives the bootp request with option 77, but response from dhcp server to switch doesnt have the image details !
Also Switch is configured with "default boot iPXE" is receiving the ip address from DHCP server, but there is no response after that! (stuck)
