Opened: Oct 20, 2016 Severity: 3-Major
When upgrading from v11.5.3 to v11.6.1, DHCPOFFER packets got silently dropped.
BIG-IP will stop to relay DHCPOFFER and DHCPACK back to DHCP clients
If DHCP clients send broadcast DHCP packets with non-zero unicast source IP address via BIG-IP, and regular DHCP discovery packets(0.0.0.0 source IP addrees), multiple client connection flows are created, after some are aged out, BIG-IP may stop relay DHCP server replies back to clients.
Manually delete all system connection flows by doing "delete sys conn" under tmsh.
