Remove Packet Header Information

The Header Stripping feature is a licensable addition to the GigaSMART® engine that removes tags, headers and encapsulations that can interfere with packet analysis tools. Header Stripping efficiently examines packets for specified headers, such as MPLS, VLAN, VXLAN, VN-TAG and GRE, and removes them before sending the packets to the appropriate security and analysis tools. For tunneled or encapsulated traffic, such as ERSPAN, GTP and ISL, both the header and the trailer are removed before the packet is sent to its destination. Header Stripping can also be used to remove or convert FM6000 timestamps to UTC, and then append them to the packets as a trailer. In addition to stripping VLAN tags, this function can also add or replace VLAN tags.

Benefits of the Header Stripping Feature

  • Allows analysis and monitoring tools to process traffic flows that they otherwise could not recognize because of an unreadable header type.
  • Significantly improves the performance and efficiency of tools that are capable of recognizing various header types, by offloading this processor-intensive function.
  • Enables monitoring and analysis tools to readily interpret traffic collected from inter-switch and trunk links.

GigaSMART Features

GigaSMART® offers several essential traffic intelligence services required for deep observability into infrastructure blind spots.

NetFlow Generation

Delivers basic Layer 2–4 network traffic data to analysis tools.

Source Port Labeling

Provides context to packets and identifies behaviors and threats based on network location.

Adaptive Packet Filtering

Identifies patterns across any part of the network packet, including the packet payload.


Targets, identifies, and eliminates duplicate packets, blocking unnecessary duplication and sending optimized flows.

Packet Slicing

Truncates packets while preserving the protocol headers required for network analysis.

Advanced Load Balancing

Divides and distributes traffic among multiple tools based on a variety of data points.

Advanced Flow Slicing

Reduces bandwidth usage by slicing payloads and packets from long data flows.


Provides customizable data protection by overwriting specific packet fields with a set pattern. 


Alleviates blindness of business-critical traffic at remote sites, virtualized data centers, or in the public or private cloud.

Application Visualization

Provides a complete view of the applications running on your network.

Application Filtering Intelligence

Extends Layer 7 visibility to thousands of common and proprietary applications.

Application Metadata Intelligence

Provides application visibility to identify performance and quality issues, and potential security risks.

GTP Correlation

Enables mobile service providers to monitor subscriber data in GPRS Tunneling Protocol tunnels.

FlowVUE Flow Sampling

Provides subscriber IP-based flow sampling.

5G Correlation

Forwards subscriber sessions to specific tools by filtering on subscriber, user device, RAN, or network slice IDs.

SSL/TLS Decryption

Creates a secure channel between the server and the end user's computer or other devices as they exchange information.
