Microsoft OCS 2007 and Cisco ACE

[Jaime Soto Valenzuela]

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.
