When a CVP cluster is deployed in a different location from the devices under management, it is possible that it

DPS (Dynamic Path Selection) provides the ability to select different paths for different types of traffic to optimize application performance.

Dynamic NAT connection limit is a feature that provides the functionality to limit the number of dynamic NAT connections.

This feature extends the capabilities of event monitor to include NAT logging. The tracked events are NAT translations creations, NAT translations updates, NAT translations deletions and NAT translations deletion reasons (aging deletion, aging deletion(hw not programmed), peer deletion)

NAT (Network Address Translation) is a feature that allows each packet's addresses to be rewritten according to the user configuration. The packet qualification happens within the ingress pipeline of the forwarding plane, then the egress pipeline uses a shared table memory to decide which fields to adapt.

This feature, when enabled, allows NAT to function on traffic traversing between VRFs, over inter-VRF static routes or routes leaked to VRFs other than where they were configured.

Support for IPSec connections in a full-cone Network/Port Address Translation (NAT) environment has been added to the Dynamic Path Selection (DPS) setup. DPS optimizes application performance by selecting different paths for various types of traffic. In this configuration, STUN is used to discover the translated IP address of WAN interfaces and export it to BGP.

The NAT Flow feature is an unusual NAT feature that allows the translation of traffic streams in ways that go beyond the typical translations achieved with NAT. In that sense, the feature is not strictly a standard NAT feature; it can be seen as a combination of NAT and DirectFlow.

The ICMP protocol has a type of messages used to handle problematic situations in a network, like for example destination unreachable, packet's Time To Live exceeded, and others. They all contain the "original datagram" field which represents the leading octets of the datagram to which the ICMP message is a response. The original datagram consists of the IP header + at least 64 bits of the data.

NAT Peer State Synchronization feature provides redundancy and resiliency for Dynamic NAT across a pair of devices in an attempt to mitigate the risk of single NAT device failure. Each switch advertises connection state updates to its peer.  State update consists of connection creation, connection state change (TCP mostly) or connection tear down

Non default VRF support is now available for Static unicast NAT. Twice NAT. Dynamic NAT. VRF support

This feature allows the packets to be VxLAN encapsulated after NAT translation, Reverse NAT translation applied on VxLAN tunnel terminated packets

Some configurations in NAT may have some trade-offs and even cause problems. The Show Configuration Consistency NAT CLI can check these configurations, and provide hints to change the configuration or the trade-offs to be considered. 

NAT has been supported in DCS-7150 for many years. Starting at EOS 4.21.6F, NAT functionality is supported on certain 7050X3 platforms.

Hardware accelerated NAT for transit fragmented traffic is enabled by default. It’s important to note that

Multicast NAT is a feature that performs NAT translations on multicast traffic. It can be configured under SVIs,

This feature allows for the configuration of password requirements when creating or modifying local user accounts. Specifically, policies can necessitate that passwords meet the following requirements:

Static NAT rules may optionally include an access list to filter the packets to be translated.
