Failover for UDP Performance Layer 4 with One (1) Connection
Hello, I am using the F5 to hopefully load balance or serve as an active-passive configuration for my firewall log pipeline. My firewall successfully sends logs via UDP to the F5 and they make their way to the configured pool member and are visible within my log collection environment, so that works. I tried adding a 2nd server to the pool, but there is no load balancing because there is only one active connection from my firewall. That makes sense. I figured the next best thing that I could attempt was to configure failover so if one node with the active connection goes offline, then my second node will pick up the traffic. I added both nodes to my pool today and turned off the service on my node with the active connection. The F5 UDP health monitor marked the primary node as offline, but the active connection never failed over to the secondary node. I was expecting the F5 to transfer the connection to the secondary node, and I am a bit confused as so why it did not. As I understand, this is potentially because of the connectionless nature of UDP. However, since the F5 marked the node as offline, I thought it would be able to failover the connection. Do you know of any way to enable this active-passive configuration with the F5 using UDP protocol, Performance Layer 4, and two nodes in the pool? Thanks!
Standby Appliance receives HTTP Requests.
Hello Pros, I am working on a weird issue. Where customer is using BigIP 8900 11.2.1 HF10. While performing health-check for a customer, I observed that standby unit was showing some HTTP Connection in the QKview graphs. Since it is standby unit, it was a little surprising, and I requested for a remote session to validate the issue. I found that a few VS were showing "current connection" count to 2 or 5 in VS Statistics. Just out of curiosity I want to know that under which circumstances we can see such result? Thank you, Darshan
Standby Appliance not close connection
Hi community, today i find a strange issue. I've an HA pair appliance, Active - Standby. I've forced Standby the applianceA and the applianceB become Active. I check the VS statistic of the standby (appliaceA), but after 1days 4vs have 10k of current connections. I've forced the disable status on the VS and the session decrease. If i reactivate the VS, the session grow as previous the disable action. If i check the state of the pool, they are all at 0 current connection. The active appliance process all the traffic correctly and no disservice occur. I've 10.2 version and the external interface is on internet. What could be the issue? Why if it is standby the session grow? Thanks! -AB
