dhcp snooping enabled, but not seeing any entries

[frodalf]

Hi everyone, first-time poster :)

I have configured dhcp snooping on three 5130 switches which are running version 7.1.045 release 3109P05 software using the following configuration:

interface Bridge-Aggregation56
 dhcp snooping trust
#
dhcp snooping enable

However, when I enter the command "display dhcp snooping binding" I do not see any entries. As far as I can tell DHCP snooping is working, as "display dhcp snooping packet statistics" shows the number of packets sent and received steadily incrementing, but I'm puzzled as to why I don't see any entries?

I configured this up on some 5120 switches running version 5.20 release 2208P01, using just the above commands, and the command "display dhcp snooping binding" DOES show me entries as I would expect.

Is there something additional I need to do on the 5130? Unfortunately I can't play around until I find what works, as the only 5130 switches I have available are all in production and subject to strict change control.

Thanks!

Well hopefully I have found the answer - looks like I need to configure "dhcp snooping binding record" on every client-facing interface, which I wasn't aware of - so will be trying this in a few days.

Success! I have configured "dhcp snooping binding record" on every client-facing interface, and now "display dhcp snooping binding" is showing the entries which I expect. :)
