Force10 MXL 10/40 dhcp snooping issue

This configuration from switch with server connected to it and at this moment we're trying to implement snooping in single vlan. Port with server was configured as trust and after that this message appeared in the log and non of the clients are getting ip from this server.

I believe there should be option to allow empty giaddr field like it exist on Cisco gears

Here is current config, dhcp snooping disabled globally since chassis is in production at this moment

ow-ch05-switch#sh ip dhcp snooping

Ports number 44 are uplinks, 9 and 4 are dhcp servers half-size blades.

I tried both options with and without "information-option trust-downstream", but nothing changed

Thanks for checking this. Yes, I got same warning, we're using VLAN 1 as default/native, but most access ports configured as tagged for numerous of vlans and my DHCP connected to VLAN 30. I don't think this warning could break everything.

Hello, Daniel, thanks for your help

Sorry for confusing situation, let me clarify everything one more time in order to give you more wide understanding about existing issue. You're not seeing list of VLANs because there were 4094, one in a row, that's why I didn't post them.

We have tested 2 different cases for dhcp snooping feature in chassis switch, I'll provide explanation below:

1. MXL 10/40 connected to Cisco ToR switch, DHCP client connected to MXL switch and DHCP server connected to ToR switch. In this configuration everything was fine, MXL determined DHCP client host, added entry to snooping table and etc. Everything in the same VLAN

2. DHCP server and client connected to MXL switch, same configuration, server's port configured as trusted, but DHCP client never receives IP from the server

We tried different DHCP servers, dnsmasq and isc-dhcpd

Found post similar to mine. Just adding here for history
