Looking for help with F5 BIG-IP iRules development for custom HTTP header processing. We're trying to modify incoming request headers based on client IP geolocation, but the iRule is causing connection timeouts on certain requests. The logic works for most traffic but specific user agents seem to trigger infinite loops in the header rewrite code. Need someone experienced with iRules scripting and HTTP event handling to debug the conditional logic. Seeking 2-3 hours remote troubleshooting to identify and fix the timeout issues. Must be resolved by Thursday for production deployment.31Views0likes1Comment4600 rSeries tenant resizing and HA Dependency
Consider there is an HA between 2 tenant. rSeries Chassis 1 - Tenant1 - F5 VM ( Active F5 ) rSeries Chassis 2 -Tenant1 - F5 VM ( Standby F5 ) If Chassis 2 - Tenant 1 is resized for resource perspective ( cpu ) , and put the state into Deployed state , in F5 VM level , will it be automatically be part of HA or both tenant need to have same Hardware resource allocated ?30Views0likes1CommentCookie persistence and source address fallback
I wonder what will be result of such setup: LB set to Round Robin Default Persistence Profile: Cookie (Cookie Insert) Fallback Persistence Profile: Source Address Source IP same for all requests (SNATed) My assumption is: First new TCP connection established, no cookie present Fallback Persistence used, no Persistence Record (PR) found No persistence is applied because none exist so connection will be directed to first member What will happen then? Persistence Record for source IP will be created pointing to first server? In HTTP response cookie is inserted pointing to first pool member Then second connection from the same IP comes, assuming that PR was created and did not time out then LB will be ignored and connection will be directed to first server In HTTP response again cookie pointing to first server will be inserted Then all returning connections (with cookies set) will be directed to first server, LB in fact will not be used, except for situation when there is enough period of inactivity between connections to allow PR to expire, but will then new connection be send to second server according to RR or not necessarily? Is above correct? PiotrSolved1KViews0likes19CommentsF5 APM - limiting access to the bandwidth for network Access
I am looking for a way of restricting access to the available bandwidth for our SSL VPN users. I see within the 'Network Access' configuration (Network Settings) there is an option to set 'Client Interface Speed' in bits per second. I have attempted to find more information on this without much luck. The only references I can find are below: 'Specifies the maximum speed of the client interface connection, in bits per second.' 'Specifies the speed of the client interface connection, in bits per second.' Can anyone provide further insight to this particular setting? I want to confirm/understand: (1) if this is actually a bandwidth restriction or whether it is just an administrative setting (though the above suggests a restriction) (2) if it is a bandwidth restriction, does this perform Traffic Policing or shaping? (3) is the setting per client connection, or all connections using that particular 'network access' Thanks1.2KViews0likes7CommentsUnexpected Error: UCS loading process failed
Hello, I'm taking the LTM Essentials course online. There are different labs and before each lab, I need to upload a UCS file and restore it. But when I do the restore, I receive the following error: Unexpected Error: UCS loading process failed. It is impossible to have the restore working. Somebody would have an idea how to troubleshoot this? Thank you, Vinch750Views0likes3Commentsnetwork failover/serial cable for HA
for HA configurations, there are 3 options network failover in network failover the heartbeat is the network packet serial failover serial cable failover is just checking a voltage heartbeat between the two systems. network and Serial failover I not sure does it mean failover only take place when network and serial both are failed or ? if use both, how to test if it is working?Solved1.4KViews0likes14CommentsSharing same VLAN between vCMP guest
Hello, This question is regarding to sharing same VLAN between vCMP guest for F5 viprion platform. lets say, I have a VLAN 10 which is tagged to interface 1.1 at vCMP host level and propagated to Guest A in common partition. -For the guest B can I use same VLAN? -What would be the recommend way to share VLANs between guests? -Can we tag VLAN 10 to 1.2 interface at vCMP host level and share it with Guest B?616Views0likes2CommentsBIG-IP to Cisco via 10Gb SFP+ Direct Attach Copper
Hi, Anybody using Cisco DAC 10G transceiver/copper cables (TwinAx) to connect from a Cisco switch to a BIG-IP? Can't seem to find an answer, suspect it is not supported which is always an issue for DACs between vendors. Cheers1.7KViews0likes14Comments
