Flushing Source address persistance for a singe Virtual ?

Hi Ian,

 

 

You can use 'b persist virtual VS_NAME show all' to list the entries and 'b persist virtual VS_NAME delete' to delete them.

Hey Aaron , wonder if you could help again :

 

 

is there a way to clear a specific record from the persistence table when using source address persistence ?

 

 

additionally , is there a way to generate a record for a specific host , i.e. sent client X to server Y

 

 

Before you ask , i know this is random requests , but we are having issues with the intermittent performance of a server , and want to set a one client to use a specific server to allow us to narrow the fault domain down.

 

 

Thanks

 

Ian

Hi Ian,

I haven't tested this, but I think you can use 'b persist client 1.1.1.1 delete' to delete a client's persistence records.

I don't think there is a way to add a persistence record using the 'b persist' command. If you want to isolate one client to a specific pool member on a temporary basis, you could use an iRule which checks the client IP address and specifies the particular pool member:

 
 when CLIENT_ACCEPTED { 
  
     Check if client is 1.1.1.1 
    if {[IP::addr [IP::client_addr] equals 1.1.1.1]}{ 
  
        Force the client to the current pool's 2.2.2.2:80 member 
       pool [LB::server pool] member 2.2.2.2 80 
    } 
 }

Thanks Aaron , i can confirm the command to delete a single client does work ..

Do you know how I can do this for a Virtual Server that isn't in the Common partition? I changed the persistence method for a Virtual Server from source address to Universal persistence using the JSESSIONID in an iRule. Since I did this the source address persistence records haven't gone away in over two weeks. When I tried the command you suggested I get the following error:

 

 

[root@f5bigipa6:Active] config b persist virtual VS_Name delete

 

BIGpipe unknown operation error:

 

01070823:3: Read Access Denied: The current update partition (Common) does not match the object's partition (Partition_Name), stats not reset

 

 

Do I need to adds something to the command? Or logon as an admin user for the particular partition and do the same command?

 

I know it has been a while but just in case anyone else stumbles upon this post by searching for the error message, here is the command to switch partitions in the shell.

 

 

'b shell partition "partition_name"'

 

 

Then run the commands above to clear persistence.

 

and what is the tmsh equivalent of the b command to do this? ahem...

 

thanks.

 

try this

 

 

15 13 * * 0 export REMOTEUSER=root ; tmsh -c "delete ltm persistence persist-records virtual nameofvirtualserver"

 

thanks.. that does it. also found a document that maps bigpipe to tmsh equivalent.. whew...
