N/A.
NAT maps IP addresses from one address domain (typically a private IP address space) to an another address domain (typically a public Internet IP address space) to provide transparent routing to end hosts. This translation is accomplished transparently by having a NAT device translate the IP address and/or Layer 4 port of the packets.
The Multicast NAT field was added to this command's output in Switch Engine 33.6.1.
Rule counts reflect all configured rules of each type, including rules that are currently disabled. Dynamic NAPT rules are system-generated entries created from live traffic flows and are included in the total rule count.
To enable or disable IP NAT, use the commands enable ip nat {unicast | multicast} and .
The following example shows output when both unicast and multicast NAT are enabled:
show ip nat Unicast NAT : Enabled Multicast NAT : Enabled Number of NAT VLANs : 3 Maximum number of NAT VLANs : 4 Number of NAT rules : 2 Number of source NAT rules : 1 Number of destination NAPT rules : 0 Number of configured NAPT rules : 0 Number of dynamic NAPT rules : 0 Maximum number of NAT rules : 1024 Aging time : 20 minutes
This command was first available in ExtremeXOS 31.2.
The Multicast NAT output field was added in version 33.6.1.
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.
