Will have a look at it this evening but from the first quick look I do
not see a problem. The server with the problem is
<font face="Courier New, Courier">slb-realsrv6? Have you tried to use
debug filter to get a trace of the traffic to this real server?<br><br>
</font>1. enable mode<br>
2. debug filter<br>
3. sp 1<br>
ip src
<font face="Courier New, Courier">150.237.196.201<br>
</font> exit<br>
sp 2<br>
ip dest
<font face="Courier New, Courier">150.237.196.201<br>
</font> exit<br>
buff 1000<br>
pack whole<br>
apply 1or2<br>
start<br>
4. send some DNS requests until the first one went to the real server
with IP <font face="Courier New, Courier">150.237.196.201<br>
</font>5. stop<br>
6. repeat for ALL BPs: <br><br>
view bp x y<br>
sum <br>
ascii 1<br>
ascii 2<br>
ascii 3<br>
...<br>
ascii n<br><br>
x = Slot number of the WSM module <br>
y = BP number you would like to check<br><br>
A WSM6-2 would have 2 BPs - asuming the module is in slot 2 you would
use<br><br>
view bp 2 1<br>
view bp 2 2<br><br>
Thanks for checking this,<br><br>

Do you mind to share your config? Have you checked what is happening
using a sniffer at the real server or via debug filter at the
ServerIron?<br><br>

Hi,<br>
We've been running ServerIronXL hardware for a few years and I've just
purchased some new chassis based replacements with WSM modules.<br><br>
I've been porting our existing load balanced services over to the new
boxes and have come across a funny.<br><br>
I provide a server load balanced DNS service via our foundry kit. and
have 3 "remote" servers defined and bound to a VIP. I've
configured the serveriron to perform a zone health check and on each of
the 3 servers I can see the health check coming in. The same real
servers are also used by our XL boxes in the interim.<br><br>
What I've found is that weven though the serveriron thinks all 3 servers
are active, when it tries to use the last one in the group of remote
servers the query never reaches the server. a sh server real doesn't show
any connections to the server. From the users point of view the query
never resolves. If i take down the dns server on the remote server so
that the serveriron health check fails, it succesfully uses the other two
servers and everything is o.k.<br><br>
I've switched off iptables on my real(remote) servers but it doesn't make
any difference. As far as i can see all my servers are identical. I have
the same setup on another serverion on our west campus with anoter 3
servers and it does the same thing.<br><br>
Anyone else seen this?<br><br>
TIA<br>
Alex <br>
