Microsoft OCS 2007 and Cisco ACE

Hi,

We are implemented Load Balancing of OCS 2007 Enterprise R2 and the clients are seeing slow and disconnection of services. The implementation is in Mode One-Arm and in the context there are also other services operating. Is there some good practice on how to implement in One Arm mode?

I attached configurations (only related to OCS).

Regards,

Jaime.

Jaime,

The following one arm mode ACE config works for me with regards to OCS:

serverfarm host ocs

  description ocs

  probe tcp-135

  probe tcp-443

  probe tcp-444

  probe tcp-5061

  probe tcp-8057

    fail-on-all

  rserver ocs02

    inservice

  rserver ocs03

    inservice

  rserver ocs04

    inservice

sticky ip-netmask 255.255.255.255 address source ocs-sticky

  serverfarm eepool01

class-map match-any ocs-cm

  2 match virtual-address 10.10.10.60 tcp eq 5061

  3 match virtual-address 10.10.10.60 tcp eq 444

  4 match virtual-address 10.10.10.60 tcp eq https

  5 match virtual-address 10.10.10.60 tcp eq 8057

  6 match virtual-address 10.10.10.60 tcp eq 135

 

policy-map type loadbalance first-match ocs-pm

  class class-default

    sticky-serverfarm ocs-sticky

class ocs-cm

    loadbalance vip inservice

    loadbalance policy ocs-pm

    loadbalance vip icmp-reply

    nat dynamic 1 vlan 300

You do not have to create multiple server-farms, class-maps and policy-maps to get this to work.

Regards,

Johnny...
