‎09-19-2012 12:44 PM

Hello, I'm configuring ACE 4710's for the first time and I want to load balance my Nuance speech servers on port 554. Here's my configuration on ACE01:

hostname ace471001

interface gigabitEthernet 1/1

  switchport access vlan 1000

  no shutdown

interface gigabitEthernet 1/2

  shutdown

interface gigabitEthernet 1/3

  shutdown

interface gigabitEthernet 1/4

  shutdown

access-list ALL line 8 extended permit ip any any

rserver host nss01

class-map type management match-any remote_access

  2 match protocol xml-https any

  3 match protocol icmp any

  4 match protocol telnet any

  5 match protocol ssh any

  6 match protocol http any

  7 match protocol https any

  8 match protocol snmp any

policy-map type management first-match remote_mgmt_allow_policy

  class remote_access

    permit

interface vlan 1000

  ip address 10.20.17.21 255.255.248.0

  access-group input ALL

  service-policy input remote_mgmt_allow_policy

  no shutdown

How would I configure my speech server to isten on 554?

Thanks in advance

probe rtsp probe01

rserver host nss01

  ip address 10.2.4.70

  inservice

serverfarm host Nuance_Lab

  rserver nss01 554

    inservice

class-map type rtsp loadbalance match-all L7SLBCLASS

  10 match rtsp url /synthesizer

class-map match-all VIP

  2 match virtual-address 10.2.4.21 tcp eq rtsp

class-map type management match-any remote_access

  2 match protocol xml-https any

  3 match protocol icmp any

  4 match protocol telnet any

    permit

policy-map type loadbalance rtsp first-match RTSP_L7_POLICY

  class L7SLBCLASS

    serverfarm Nuance_Lab

policy-map multi-match clients

Hi Reginald,

Yes, for example

class-map match-all VIP

  2 match virtual-address 10.2.4.21 tcp eq rtsp

interface vlan 1000

  ip address 10.2.4.22 255.255.248.0

  access-group input ALL

  service-policy input remote_mgmt_allow_policy

  service-policy input clients

  no shutdown

Hi Cesar,

10.2.4.22 just so happens to be the IP of my other ACE 4710. This is what I have:

2 Cisco 3945 routers with Sip proxy

1 Cisco 3750-e catalyst switch

2 Cisco Ace 4710

2 NSS servers (plus CVP, UCCX, CUPS)

That said, I do have 10.2.4.23, available.

Thanks for your help, this is my first experience with Ace.

Hi Reginald,

You will need to configure a nat-pool to avoid assymetric flows.  In addition you need to add this:

policy-map multi-match clients

   class VIP

     loadbalance vip inservice

     loadbalance policy L7SLBCLASS

     nat dynamic 1 vlan 1000

interface vlan 1000

  ip address 10.2.4.21 255.255.248.0

  access-group input ALL

  service-policy input remote_mgmt_allow_policy

  service-policy input clients

  nat-pool 1 10.2.4.23  10.2.4.23  netmask 255.255.248.0 pat ====add this line

  no shutdow

With this it should work properly.

Hi Reginald,

You still are missing the rest of the configuration in the policy-map multi-match.

It should look like this:

policy-map multi-match clients

   class VIP

     loadbalance vip inservice

     loadbalance policy L7SLBCLASS

     nat dynamic 1 vlan 1000
