Logical ports are hardware resources that are required to activate interfaces.

This feature allows a switch to statically modify the source or destination IP (and optionally the L4 port) for a transit packet. Static NAT support on 7050X3, 720XP and 720D platforms was first introduced in 4.21.6F. Starting at EOS 4.35.0F, NAT functionality is supported on certain 7050X4 and 7358X4 platforms.

Dynamic NAT is a feature which dynamically allocates an IP address to an incoming or outgoing flow. This address will replace source or destination IP for all packets of the flow. The new IP address given to the flow is from a pool of addresses called NAT pool. L4 port can also be replaced by a new one in case of NAPT (Network Address Port Translation). In address only NAT only the IP address is translated. NAPT is not supported in masquerade or overload mode.
