disable ip nat

disable ip nat {unicast | multicast}

Description

Globally disables Network Address Translation (NAT).

Syntax Description

ipSpecifies Internet Protocol (IP).
natSpecifies enabling NAT.
unicast(Optional) Disables IPv4 unicast NAT only. This is the default behavior when no keyword is specified.
multicastDisables IPv4 multicast NAT only. Supported from Switch Engine 33.6.1.

Default

N/A.

Usage Guidelines

Globally disables IP NAT on the switch. When used without a keyword, or with the unicast keyword, disables IPv4 unicast NAT only. When used with the multicast keyword, disables IPv4 multicast NAT only.

Disabling multicast NAT does not delete or disable the underlying source-nat rules. Those rules remain configured and continue to apply to unicast traffic if unicast NAT is separately enabled.

Disabling multicast NAT has no effect on unicast NAT behavior, and vice versa.

When no keyword is specified, only unicast NAT is disabled.

To view IP NAT information, run the command show ip nat.

Example

The following example disables IP NAT:

# disable ip nat

The following commands disable unicast NAT (both forms are equivalent):

disable ip nat
disable ip nat unicast

The following command disables multicast NAT independently, leaving unicast NAT unaffected:

disable ip nat multicast

History

This command was first available in ExtremeXOS 31.2.

The unicast and multicast keywords were added in version 33.6.1.

Platform Availability

This command is available on the switches that support the IP NAT feature. For information about which switches support this and other features, see the ExtremeXOS v33.6.1 Licensing Guide document.
