Order of resource assignment when user assigned multiple network access resources
Good day, What logic or method is used by the F5 APM to choose which network access resource takes affect when a user is assigned multiple network access resources? In my environment (BIG IP Virtual Edition APM+LTM 16.1.4 two node cluster) we are assigning different network access resources based on group membership. Some users are members of multiple groups that are being assigned different resources, which often is resulting them in having the "general user" settings and address pool take affect instead of the Executive settings and pool, to which they are also assigned. I haven't been able to determine the logic that APM is applying to determine which resources take precedence. It doesn't appear to be the order in the Advanced Resource assignment. It almost looks alphabetical. Thanks Chris30Views0likes1CommentIssues with F5 appliance black holeing traffic
Hi wondering if anyone can help or has seen an issue similar to this? 2 tenants on 1 Host One tenant has the issue, the other doesn't. All upstream networks and devices assurance checked and logs analysed. Issue only present on Hostname: dcnn-lb01-int.circlehealthgroup.co.uk Key Info: CPU in the control plane consistently spikes at 100% (5-10 times per min) Outbound traffic is blackholed if session starts during CPU spikes. All outbound traffic types all affected - ICMP from tmos, Node polling, F5 sync messaging, snmp messages....etc If session starts outside of CPU spikes then issue isn't present - ICMP started will run continuously without drops Symptoms last < 2secs per "CPU event". Symptoms present as if the default route drops/changes, gateway is unreachable or traffic is blackholed. Repeating here but essential to note that this is only for newly established sessions during that window. Established sessions (e.g. continuous ICMP from tmos) are not affected during the same blackholing event window where new sessions are. Thanks in advance Dave25Views0likes1Comment
