hello
I am using DHCP snooping in a company switch block. the problem is when the small business is behind a wireless link
the SW-1 configuration is :
int gig 9
> IP DHCP snooping trust
>exit
int gig 10
> IP DHCP snooping trust
>exit
IP DHCP snooping
IP DHCP snooping vlan 15,20,45
the SW 2 configuration is :
int gig 10
> IP DHCP snooping trust
>exit
IP DHCP snooping
IP DHCP snooping VLAN 45
the SW 3 configuration is :
int gig 10
> IP DHCP snooping trust
>exit
IP DHCP snooping
IP DHCP snooping VLAN 45,20
the SW 2 works just fine but the SW 3 has a problem. the clients won't get IP from the DHCP server.
after using the show IP DHCP snooping binding the mac is learned but the IP address for the mac is 0.0.0.0
Many thanks!
