http probe on non-standard tcp port 8021

I've configured http probe on standard port 80 with no issue. I'm now trying http probe on non-standard tcp port 8021, confirmed with packet capture to confirm that the CSM is indeed probing, status code 403 is returned but the reals are showing "probe failed". Am I missing something? Thank you in advance.

Re: http probe on non-standard tcp port 8021

you need to specify what HTTP response code you expect.

The command is :

gdufour-cat6k-2(config-slb-probe-http)#expect status ?

<0-999> expected status - minimum value in a range

The default is to expect only 200.

This is why your 403 is not accepted.

Gilles.
