The problem here is that the square brackets in the xpath is being interpreted as a substitution command. So you need to escape those brackets:

//td/table/tbody/tr\[contains(td\[2\],$ctlr_ip)\]/td\[6\]

If the escaping rules are confusing, another option is to concatenate different portions that allow or disallow substitutions (because of braces). Note that you can only inhibit substitution on an argument to a substitution command.

[string concat {//td/table/tbody/tr[contains(td[2],} $ctlr_ip {]/td[6]}]
