M5300-28G v1h1 (11.0.31) Missing DHCP L2 Relay

Hi LerchUK610,

Welcome to the community!                                                                                                                                                    

Yes, just as you said, some security related features(such as: DHCP L2 Relay, DHCP Snooping, DAI and so on) are limited by SDM template on v11.0.x firmware.

It depends on what SDM template that you use.
System > Management > SDM Template Preference

- If you use a template for a multicast environment, then you won't have things like DHCP L2 Relay, DHCP Snooping, DAI, etc.
- If you use a template for an environment not focused around multicast, then you will have other features like DHCP L2 Relay, DHCP Snooping, DAI and so on.

Depends on what you need to use the switch for - set the SDM template accordingly. SDM templates enable you to reallocate system resources to support a different mix of features based on your network requirements.

Pay attention: Change SDM Template will erase the configuration of the switches, so please save and export the configuration file, then restore the configuration after apply the new SDM Template.

Hope it helps!
