NAT Policy parameters

Default

The Default parameter specifies whether the IPFIX Collector Source Address parameter is included in IPFIX messages. Enabling this parameter allows you to configure the  IPFIX Collector Source Address parameter.

The options are:

• Enabled

• Disabled (default)

IPFIX Collector Address

The IPFIX Collector Address parameter specifies the IPv4 address of the IPFIX collector to which IP flow information is sent. Specify an IPv4 address in dotted-decimal format.

IPFIX Collector Source Address

The IPFIX Collector Source Address parameter specifies the IPv4 address from which IP flow information is sent to an IPFIX collector. When this parameter is not set, the IPFIX collector identifies sources by the IP address from which the IPFIX message is sent; if the source uses a proxy, this is the IP address of the proxy. Use this parameter to specify a different IP address. This parameter cannot be configured unless the Default parameter is enabled. Specify an IPv4 address in dotted-decimal format.

IPFIX Export Policy

The IPFIX Export Policy parameter specifies the IPFIX export policy for the NAT policy. Click on the Select button to choose an IPFIX export policy.

MTU

The MTU parameter specifies the MTU size, in bytes, for IPFIX messages sent to the IPFIX collector. The range is 512 to 9212. The default is 1500.

Refresh Timeout

The Refresh Timeout parameter specifies the refresh rate of the IPFIX source, in hours, minutes, and seconds. After this time, the IPFIX source resends the IPFIX template information to the IPFIX collector. The range is 0 seconds to 24 hours, 59 minutes, and 59 seconds. The default is 10 minutes.

Router Instance Type

The Router Instance Type parameter specifies the type of router instance that is used as a collector source.

The options are:

• Base (default)
