BIGIP DNS - What configuration get replicated by Sync group
Can anyone point me at some resources that explain what is replicated among devices by configuration sync on BIG-IP DNS? It seems that things like listeners and DNS profiles aren't synced so just want to understand what is and what isn't replicated. thanks Paul
BIG-IP Sync-Failover - Sync Failed
Hi, In a project we're running a device-group in Sync-Failover* mode with Manual Sync type. After a change on the Active unit trying to sync from the Active unit to the device-group, Sync Failed with the information below: Sync Summary Status Sync Failed Summary A validation error occurred while syncing to a remote device Details Sync error on 2nd-unit: Load failed from 1st-unit 01070110:3: Node address 'node' is referenced by a member of pool 'pool'. Recommended action: Review the error message and determine corrective action on the device We're totally sure that nothing had been changed manually on the 2nd node, and both nodes were in sync before the change on 1st node. The Last Sync Type field for both nodes shows Manual Full Node. I couldn't find anything on this case; is it safe to just manipulate the configuration on the 2nd node and then sync from 2nd node to the device-group? Many thanks in advance!
How to get sync information with .Net API
I apologize if this question doesn't make sense or if I'm not posting in the correct location. I am a .Net developer and never even heard of F5 until I was tasked with developing a web interface for controlling our devices. From what I was told, we have a device group of two devices that are set up as a failover. I need to determine if the devices are in sync. I have the name of the device group and the names of both devices. Determine if devices are in sync: This code works, but I'm not sure it makes sense because I would expect to be connecting to the device group, not one of the devices. However, this is the only way I could find to get the sync state. This code returns iControl.ManagementDeviceGroupMemberState.MEMBER_STATE_IN_SYNC. The reason it doesn't make sense to me is because what if the device I'm connecting to is down and the other device is now the active one? In that case, I would not be able to connect, right? Interfaces m_interfaces = new Interfaces(); m_interfaces.initialize("Device1Name", 443, userName, password); dg.SyncStatus = m_interfaces.ManagementDeviceGroup.get_sync_status_overview().member_state;
Sync config in an Active/Active cluster.
Hi, I've an Active/Active cluster and for an unknown reason, I can't Sync the config. When I do a change on one of the LTM , nothing happen. I've created the "Device Group" and added the two device in, I've set it to "Manual with Full Sync". Even after a change, the device status stay "In Sync".
Standby shows as offline in HA pair in version 12.1.2
Hello all, I know this topic has been discussed before but for older code versions and none of the solutions worked for me and I tried pretty much all of them. I have 2 3900 series boxes in HA pair. Network failover, port lockdown set to "allow all", boxes directly connected in HA vlan, no device in between. Upgraded from 12.0.0 to 12.1.2 and in the "Overview" page on the active box it shows the standby peer as "offline". If I failover to the other box it will again show the standby peer as "offline" from the new active box. Everything looks fine from the standby box "Overview". Both failover group and trust group show full sync, HA status on both boxes shows "in sync", no issues there. I tried multiple failovers, reboots from CLI, power cycles, changing port lockdown, even tried the process of forcing the configuration reload to no avail, still the same. Does anybody experience the same behaviour? I suspect this is a bug in the 12.1.2 code version.
BIG-IP : standby auto-sync to active
BIG-IP 11.4.1 Build 635.0 Hotfix HF2 For a sync-failover device-group in active-standby configuration with auto-sync enabled. What is behavior following making a config-change to standby device ( specifically, update data-group contents ) ? Will the changes be immediately sync'd to the active ? Does auto-sync ensure delta-zero between active/standby ? i.e. is it possible for active to have changes not yet sync'd to standby at time change is made to standby ?F5 APM sync issue
Sync issues seem to be a thorn in my side with APM. High availability pair, have a webtop at the end of an access policy. Failed over this morning due to a problem, and discovered that the "application access" "remote desktops" are not available on this one of the pair (call it backup), failed back (call it live) and they are working. The authentication and webtop work on both, but the icons are not displayed for accessing the applications. Session logs on backup show that the resources were assigned as expected. Indeed everything else was working as expected. Is it reasonable to assume this is a straight APM sync bug. I know there were a whole host of these, but I thought I'd seen the back of them (Currently 11.5.1 2.22.121).Manual vs Auto Sync
Hi we've had F5s in our organisation for a while now. Just recently we've developed some automation scripts that use the REST interface to the LTM module. Our problem is that our F5 HA pairs are currently manually synced. We'd like to turn on auto sync so that we can fully automate our changes but there has been some resistance within the organisation. My questions are... What are other people doing in this situation? Is auto sync viewed as an evolution of the F5 capability or just another feature available for use where appropriate? What barriers are there to transitioning from manual to auto sync?Cluster Cross subnet
Hi, We currently have two independent clusters of F5 in separate subnets (sites) and require a method for synchronizing the configuration between them. There is a restriction on the deployment where they must be in separate subnets. The two sites run active-active. The obvious issue for this is that the gateways are separate and when we attempt to synchronize the configuration, the gateway address is clobbered, resulting in the routing breaking. We've tried a few things including: sync only; doesn't synchronize everything ip gw pool w/ sync fail-over; server split routing looking at the files manually and syncing them with external script Does anybody have advice on how they would handle this situation? Thanks.
