Ace Load Balance servers in different port than VIP address

[tgandoy]

Hi,

While this is quite simple in a CSS configuration,  I could not find yet how to do this with an ACE:

- VIP address listen port TCP http

- Load balancing have  to be done between rservers 1 and 2 listen on port 8030.

So what I mean is,  users will connect to http://"vipaddress" but connections will go to rserver1 and rserver2 on port 8030.

Thanks.

Toni.

Hi Toni

In ACE it's quite simple too (but I agree may be confusing after CSS)

Basically when you create serverfarm , you put it like this :

serverfarm host X

rserver X1 8030

inservice

So, port which is going to be used between ACE and real server is specified in serverfarm.

Hey Toni,

Here you have a sample about it:

interface vlan 112

  ip address 10.198.16.71 255.255.255.192

  peer ip address 10.198.16.72 255.255.255.192

  mac-sticky enable

  access-group input ACCESS-ANS

  nat-pool 126 10.198.16.126 10.198.16.126 netmask 255.255.255.192 pat

  service-policy input ANS-MGT

  service-policy input CLIENTS

  no shutdown

class-map match-any VIP-126

  2 match virtual-address 10.198.16.126 tcp eq www

policy-map multi-match CLIENTS

  class VIP-126

    loadbalance vip inservice

    loadbalance policy POLICY

    loadbalance vip icmp-reply

    nat dynamic 126 vlan 112

    appl-parameter http advanced-options CASE_PARAM

policy-map type loadbalance first-match POLICY

  class class-default

    serverfarm SERVERFARM

serverfarm host SERVERFARM

  probe PROBE

  rserver server1 8030

    inservice

  rserver server2 8030

    inservice

rserver host server1

  ip address 10.198.16.93

  inservice

rserver host server2

  ip address 10.198.16.92

  inservice
