Hello, all!

Does Extreme switches support dhcp-option code 208 (RFC 5071)?

Thank you!

I think support for any dhcp-option code was added after EXOS 15.2, therefore, you can define any option
configure vlan <name> dhcp-option code 208 ipaddress <ip-the-option-is-associated-to>
And I think the following resource from the user guide explains this a little: http://documentation.extremenetworks.com/exos/EXOS_21_1/Security/t_configure-the-dhcp-server.shtml

Am I understand right?

It's like this:
configure vlan Users dhcp-options code 208 string "f1:00:74:7e"

configure vlan Users dhcp-options code 208 ipaddress 10.15.0.50

So what command in EXOS show name of boot-file of option 208?

(analog of Cisco's "bootfile pxelinux.0")

Thank you!

I am not entirely sure on the syntax, but you'd need to configure 209 to specify the configuration file and 210 to specify the directory location
configure vlan <name> dhcp-option code 209 string "boot.cfg"
configure vlan <name> dhcp-option code 210 string ".../isolinux/"
Again, I'd need to confirm the last two lines

I actually didn't read you last question correctly, so the above response was to "how do you configure the bootfile".  Let me not speculate, I'll try and see

You can find the supported RFC for EXOS in this document:
