failed to sync config to peer

Hi Friends,

 

I encountered a issue about config-sync of BIGIP VE lab environment, HA is established(active/standby) but the status is "Not All Devices Synced" all the time, one of member's sync status is always "Does not have the last synced configuration". I tried v11.6.0/v11.5.3 and rebuild the config several times but still the same, config cannot be sync to peer device. Kindly help me with this frustrating issue and let me know if something missed. Thanks a lot!

    Hi,

     

    So first of did you manage this notification:

     

    Bandwidth utilization is 2 Mbps, exceeded 75% of Licensed 2 Mbps

     

    THis notification occur when The throughput rate exceeds a percentage of the maximum licensed throughput rate on the BIG-IP system https://support.f5.com/csp/article/K99532652

     

    keep in mind that the HA link also consumes bandwidth. so the mirroring and synchronization part increases your bandwidth and impacts your license which only restricts you 2 Mbps... but that's another problem.

     

    What I recommend at first is to change your synchronization method:

     

    • edit your device group (Device Management ›› Device Groups ›› dg-name)
    • switch "Sync Type" to "Manual with full sync".

    Keep me in touch.

     

    regards
