IP Fabric 2.3.0: MPLS, NAT & Port Mirroring

Today, we are pleased to release the new version 2.3.0 of IP Fabric platform. This release assists engineers in having a more complete overview of their network by adding support for additional technologies that are especially seen in Internet Service Provider and enterprise Internet Edge environments — Multiprotocol Label Switching (MPLS), Port Mirroring and Network Address Translation (NAT). We have again improved usability of graphs, that now support site renaming directly in graphs and also support visual separation of site interconnects from the general transit clouds.

Features — Protocols and Technology Support

Multiprotocol Label Switching (MPLS)

Frequent feature request from Internet Service Providers and Enterprise customers as well was Multiprotocol Label Switching (MPLS) support. In this release we are adding full support for Label Distribution Protocol (LDP), where we provide the network operator with detail about configured interfaces and what are the LDP neighbor relations, and we also provide with global network MPLS Forwarding Table that is very similar in function to a global routing table we have already. The MPLS is of course supported in graphs as well.

MPLS support in Diagrams

Network Address Translation (NAT)

Network Address Translation is pretty common in the enterprise Internet Edge service block and particularly in ISP networks to “sort out” their IPv4 address exhaustion issue. Today we are releasing support for Network Address Translation rules, to give you full End-to-End visibility and packet behaviour.

Port Mirroring (SPAN)

To support traffic recording efforts of our clients we are introducing support for port mirroring overview and configuration verification. Regardless if the technology used is Switched Port Analyzer (SPAN), RSPAN (Remote SPAN) or ERSPAN (Encapsulated Remote SPAN), we are supporting the overview tables including all the low level details like ACLs applied to the monitoring session or QoS used for the mirrored traffic.

Diagrams Improvements

Easier site renaming

The graphs are definitely one of the most used functionalities of our product. Many of our clients inquired for the functionality to be able to rename sites in easier way and we are now supporting renaming of site directly in the site diagram.

Site Renaming in Graphs

Multiple transit separation

To get better overview about how the specific sites are interconnected, we are now introducing the separated transits for other sites in the diagrams. This way you will be able to find out what is connected to what much faster than before.

Easier diagram orientation

When the graph is opened through the hostname link in any table, it will zoom automatically to that specific device.

OUI setting

There are couple vendors out there that are using for their devices Organizationally Unique Identifier (first half of MAC address specific to vendor) that are belonging to other companies. This was causing issues during device discovery as our platform is connecting to well-known vendor OUIs, because we don’t want to log onto everything in the network, but just the network devices. However if you happen to have a device with special OUI portion in its MAC address, this is no longer an issue and you can override the default behaviour and select the MAC addresses, that are relevant to your environment.

Further improvements

We have worked hard on improvements in datacenter portfolio, where we improved support for Cisco Nexus Fabric Extenders (FEX) modules and their environmental parameters. For the memory hungry devices we have added a support for memory consumption overview — this can be used to verify if your network will support further IPv4 BGP routing table growth or it is running already at its' limits.
