Unfortunately this doesn't seem to happen. These are my current rules: > Darren, Why can't you just use Source IP persistence with WLC? -- Regards, Malcolm Turnbull. Hi Malcom. Thanks for the reply (and sorry for the Outlook-quoting). I'd discounted persistence as I understood it to be only for making each connection persistent, but thinking about it again that doesn't make a lot of sense! Am I right in thinking that if a single client makes its first connection to node1 then as long as there are connections made before the persistence time-out they will be made to the same real server again? But then if the weight changes to 0 on node1 new connections will be made to node2 regardless of the persistence time-out? (as should happen on SH but doesn't).
