Cat8540 - DHCP through Transparent bridging

We bridged two sites but DHCP service doesn`t work when DHCP server is on one site and clients on the other site. I tried ip helper-address but it doesn`t help. Is there any other way to run DHCP service at Transparent bridging?

Re: Cat8540 - DHCP through Transparent bridging

commands are as follows:

[no] ip inspect name L2-transparent dhcp-passthrough

p26-24.12(config)#ip inspect ?

L2-transparent Transparent Mode commands

...(existing inspect commands)

This command enables the DHCP passthrough behaviour in the feature. New features like ARP inspection will follow the L2-transparent keyword along with dhcp-passthrough.
