Known Affected Releases


Description (partial)

DHCP snooping database is not being created on a 3650/3850 running IOS XEversion 3.3.1. DHCP snooping bindings are created fine but they are being lost upon switch reload as there is no database. This is causing traffic black holing until dhcp is renewed on all clients after switch is reloaded.

So far this has been seen on catalyst 3850/3650 switch with unsynchronized NTP.
