Hello,
I have a situation where I want to redirect traffic from port 80 on the
vip to port 81 on the 2 reals that are part of the group associated
with the vip. I thought this was a as simple as using rport under
/c/slb/virt/service. The alteon insists on a filter, so I put one on
port 1 that just does an action allow. The alteon doesn't complain
about the config since I added the filter, but it doesn't redirect the
traffic to port 81 - it just keeps sending vip:80 to reals:80.
What's going on? Is there more to redirecting a port?
Brian

The filter you describe should not effect SLB function at Alteon
platform unless there is a mis-configuraiton. Is the port 1 a server or
client port ?? Anything else at the filter? You can simply redirect the
real port by only using "rport" command. You can check wether the SLB
funtion works properly by using "/info/slb/dump" or
"info/slb/sess/dump" .This command will help you a lot.

I think it is just easier if I post the output from /info/slb/dump
(below):
Also, I am on Web)S 9.0.43.11. Does it have bugs that might affect
this?
Can you email off-line? bchill ^ bch.net
Thanks!

As I know, the redirtion of WebOS 9.0.43.11 is good. From the dump,
your real server works well and port 1 is server port. There is a
concept of filter; A filter can be only triggered while the session or
packet is not responed to SLB. In other words, your filter is not
necessary for redirection. You can remove it.
