Re: what is the ip protocol no used in the failover messages

In order to support the stateful failover, a dedicated LAN interface between the two PIX devices is required. The Logical Update (LU) is the software module that provides transport to PIX applications that support stateful failover. The state update occurs from the active to standby through the LAN interface. The state update sent to the standby PIX is triggered by the application. The LU transport is UDP-like, with no retransmission and no blocking applications to delay normal packet processing. The state update packets are transmitted asynchronously in the background. Nevertheless, the LU protocol is real-time, and it provides error notification and reports missing state updates for monitoring purposes.
