In this week’s Post of the Week, Joe talks about using iControl to automate the process of bleeding off connections from a server, then bringing it all the way down once all connections have closed. Thanks to poster nevot from Spain for a great question demonstrating how iControl can help automate a common change control function. BTW, sorry for the background noise. Remind me to shut down my BIG-IP next time B-). Here's a link to the post: iControl graceful stop node. Technorati Tags: F5, DevCentral, Post...

After reviewing the relative merits of a the suggestions and warnings offered by several respondents, it seems the best solution is an iControl call to modify the pool configuration when required.

This week’s Post of the Week is based on the post GTM and IP selection by poster cknail. He was looking for a solution to hand out the same IP address for LTM virtual servers in different data centers, in support of devices that don’t honor the short TTL asserted by GTM. After an interesting discussion by several F5 engineers regarding the interplay between LTM and GTM regarding monitoring VS status, it turns out that the best solution is LTM only with the ARM (Advanced Routing Module) licensed and configured...

“Switch” Gone Wild This week Deb looks at a post from gregt, who was having some trouble with choosing a pool based on the requested URI. Posters aherrman and cmbhatt (CB) jump in to correct the logical order of comparisons (most specific first, please!). CB further suggests using switch with wildcards to replace the nested “if” commands that used “starts_with” and “ends_with”. You’ll probably want to pull up the post to follow along on this one, so here it is: iRule sends to wrong Pool and Port...

Rewriting Post Data This week Deb solos, reviewing a post from laserman about some challenges he faced when terminating SSL on LTM: When rewriting self-referencing links in the payload to https, the resulting self-referencing POST submissions needed to re-written back to http again before forwarding to the server. The solution hoolio offers is use an iRule to selectively apply a stream profile against the inbound data. Thanks for an interesting topic, guys!

Poster mgabaldon offers some excellent insight about a possible iRule solution. Here’s the post: struggling with "action on service down" Colin & Deb discuss the iRule solution further, and offer some insight about how to configure LTM’s Action on Service Down option. The settings for Action on Service Down are explained in more detail in this tech tip:...
