Microsoft OCS 2007 and Cisco ACE

Jaime Soto Valenzuela · ‎06-30-2010

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.
