Hey guys !
After some test I can't figure what I'm doing wrong ..... BTW all the interface are in the same VLAN .. So I don't know why i'm getting this issue.....
PS : after disabling ip dhcp snooping , I can get an IP address ... so my DHCP are OK
PS 2 : After configuring all the other ports with the limit rate, they appear as untrusted in the show ip dhcp snooping . and now my PC can get an IP
Sorry for flooding the forum but that topic can serve to another student
OK I got the point !!!
Be aware guys that when you do a :
ip dhcp snooping
it will enable the : ip dhcp snooping information option (DHCP relay option 82) .
And some DHCP server does not accept the Option 82 .. (no response)
so here is the answer : no ip dhcp snooping information option .
Then my wireshark shows me heaven !
DHCP Discover (Broadcast)
DHCP Offer (Unicast)
DHCP Request (Broadcast)
DHCP ACK (Unicast)
WOOT ! Got my answer
thank you for this post. I lost some days trying to understand why this happens... I have a 3550 with EMI ios and I tried the DHCP snooping, but doesn'work... The problem was the same: the client can't get ip addres when dhcp snooping is working.
I will try your solution ASAP.
Best regards and... Merry Christmas!
