Alcatel Unleashed

Hello Guys
it is the first time I am posting here
we have alcatel swithces(6450)
I have enabled the DHCP snooping

ip helper dhcp-snooping enable
ip helper dhcp-snooping binding enable
ip helper dhcp-snooping linkagg 1 trust

it is working properly

but my problem is with our WDS server
when I enable DHCP snooping we can't deploy the operating system through PXE
can you help please

This is correct. For PXE to other vlan you need
ip helper pxe-support enable.

But you can't use ip helper and dhcp snooping at the same switch. But normaly you need ip helper only at your L3-switch (core) and dhcp-snooping only at your L2-switch (edge). So it should not be a problem.
