ASA 5506W DHCP on Port Channels - does it work?

Got a shinny brand new ASA5506W.  ver. 9.4(1) ASDM 7.4(1) . First time working with them. 

***Note to Cisco  - I'm disappointed that it is not clearly stated that the ports are not switch ports. With your marketing material it is very easy to assume they are.***

 

Want to use ports 1/2 - 1/7 as common switch ports so I configured them as Port Channels.

 

DHCP does not work on Port Channels but does work on Inside Interface 1/1.

 

Can someone a) verify if DHCPD will in fact work on Port Channels and if it is supposed to work, then b) help!

 

Here's my config:

: Hardware:   ASA5506W, 4096 MB RAM, CPU Atom C2000 series 1250 MHz, 1 CPU (4 cores)
:
ASA Version 9.4(1)

Hi,

This should work. What are you seeing in the debugs ?

Check for these while trying to connect a DHCP client PC to the ASA interface:-

debug dhcpd event

debug dhcpd packet

Thanks and Regards,
