6. Set the real server group metric to minmisses. This setting helps minimize cache misses in the
event real servers fail or are taken out of service.
7. Verify that server processing is disabled on the ports supporting application redirection.
Note: Do not use the server setting on a port with application redirection enabled. Server
processing is used only with SLB. To disable server processing on the port, use the commands
on the /cfg/slb/port menu, as described in the Alteon Application Switch Operating System
Command Reference.
8. Create a filter that will intercept and redirect all client HTTP requests.
The filter must intercept all TCP traffic for the HTTP destination port and must redirect it to the
proper port on the real server group.
The rport (redirection) parameter must be configured whenever TCP/UDP protocol traffic is
redirected. The rport parameter defines the real server TCP or UDP port to which redirected
traffic is sent. The port defined by the rport parameter is used when performing Layer 4 health
checks of TCP services.
Also, if NAT and proxy addresses are used on Alteon (see step 3
), the rport parameter must be
configured for all application redirection filters. Make sure to use the proper port designation
with rport. If the transparent proxy operation resides on the host, the well-known port 80 (or
HTTP) is probably required. If the transparent proxy occurs in Alteon, make sure to use the
service port required by the specific software package.
For more information on IP proxy addresses, see IP Proxy Addresses for NAT, page 464
