Chapter 9 High Availability for FortiOS 5.0 : FortiGate Session Life Support Protocol (FGSP) : Verifying FGSP configuration and synchronization : FGSP configuration summary and status
  
FGSP configuration summary and status
Enter the following command to display a summary of the FGSP configuration and synchronization status:
diagnose sys session sync
sync_ctx: sync_started=1, sync_tcp=1, sync_others=1,
sync_expectation=1, sync_redir=0, sync_nat=1.
sync: create=12:0, update=0, delete=0:0, query=14
recv: create=14:0, update=0, delete=0:0, query=12
ses pkts: send=0, alloc_fail=0, recv=0, recv_err=0 sz_err=0
nCfg_sess_sync_num=5, mtu=16000
sync_filter:
1: vd=0, szone=0, dzone=0, saddr=0.0.0.0:0.0.0.0, daddr=0.0.0.0:0.0.0.0,
sync_started=1 shows that synchronization is working. If this is set to 0 then something is not correct with session synchronization and synchronization has not been able to start because of it.
sync_tcp=1, sync_others=1, sync_expectation=1, and sync_nat=1 show that the FGSP has been configured to synchronize TCP, connectionless, asymmetric, and NAT sessions.
sync: create=12:0 and recv: create=14:0 show that this FortiGate has synchronized 12 sessions to its peer and has received 14 sessions from its peer.
sync_filter shows the configured FGSP filter. In this case no filter has been created so all sessions are synchronized.
vd=0 indicates that root VDOM sessions are synchronized.
