NAT Configuration Syntax

Prognosis for Unified Communications only

The NAT Configuration file provides a means of specifying the mapping between the IP addresses of the devices, as seen by CUCM, and the IP addresses as seen by the Prognosis Monitoring server. Mapping in the NAT Configuration may be specified for a specific cluster and/or globally for all clusters.

SUBSYS NAT
NAT-MAP CLUSTER (<id>, name=<cluster>, source=<sourceIP>, dest=<destIP>,
mask=<subnet>)
NAT-MAP GLOBAL (<id>, source=<sourceIP>, dest=<destIP>,
mask=<subnet>

Syntax Elements

NAT-MAP CLUSTER
This defines a translation that is applicable to a single cluster within a Cisco Unified CallManager environment.

<id>

any unique Id, suggest using sequential numbers

 <cluster>

Name of the cluster that this NAT mapping is specific to

<sourceIP>

IP address as seen by the CallManager

<destIP>

IP address as seen from the managing node

<subnet>

Subnet mask range

NAT-MAP GLOBAL
This defines a translation that is applicable to all clusters within a Prognosis environment.  If there is a global default and an override for a specific cluster, then the overridden value is used in the translation.

<id>

any unique Id, suggest using sequential numbers

<sourceIP>

IP address as seen by the CallManager

<destIP>

IP address as seen from the managing node

<subnet>

Subnet mask range

Example:

NAT-MAP CLUSTER(1, name=CCM5_Cluster, source=10.3.0.0, dest=10.4.0.0, mask=255.255.0.0)
NAT-MAP CLUSTER(2, name=CCM5_Cluster, source=10.1.1.0, dest=10.3.1.0, mask=255.255.255.0
NAT-MAP CLUSTER(3, name=CMC6_Cluster, source=10.1.1.0, dest=10.3.1.0, mask=255.255.255.0 )
NAT-MAP GLOBAL(4, source=10.1.1.0, dest=10.2.1.0, mask=255.255.255.0)
** NOTE **
1. Cluster NAT mappings take precedence over Global NAT mappings.
2. For a given cluster, source or destination IP addresses must not overlap or the configuration will not start.
3. For Global NAT mappings, source or destination IP addresses must not overlap or the configuration will not start.
