GigaVUE Concepts and Programming Course Outline

<< RETURN to the Training Schedule.

Course Description:

Data access network (DAN) was introduced by Gigamon in 2005 with the introduction of the GigaVUE-MP data access network switch (DAN switch). A DAN switch is not a traditional data switch or router. It is designed to gather data from multiple locations on a network simultaneously, and deliver specific packets to different monitoring and security tools.

This class covers the many aspects of the GigaVUE data access switch relating to its operation, programming, and troubleshooting.

At the end of the class students should have a good understanding of the major issues addressed by the GigaVUE, how to set it up, program it for packet flow distribution (mapping) to tools, and the concepts and principles behind it as well as hands on programming experience.

The training classes cover the following topics:

Section 1:

Introduction to GigaVUE/Gigamon

Section 2:

Solving Network Access Problems with GigaVUE

• Asymmetric Traffic Flow
• Big Pipes: Monitoring 10G Traffic with 1G Tools
• Improve Tool Performance Through Aggregation and Mapping/Filtering
• Best practices
• DAN architectures

Section 3:

How GigaVUE Works: Concepts, Connections and Maps

• Any to Many, Traffic Replication, Port Filtering to Customize Egress Traffic
• Many to Any, Traffic Aggregation, Bulk Filtering Ingress Traffic to Avoid Congestion
• Mapping, Sending Specific Traffic to Each Tool

Section 4:

• Base system description
• Ethernet Management Port
• Serial Console Port
• 10 GigE Port
• G-TAP family of passive optical 10G/1G taps

GigaVUE Modules

• GigaPort Module, for SPAN or External Tap Connections, Fiber or Copper

• GigaTap-SX/LX, Integrated Tap for 1G Fiber Links
• GigaLink-Cu/SR/LR/ER, 10G CX-4 and/or Fiber Port for stacking, network or tool connections
• GigaSMART Plug-in Module

Section 5:

Programming the GigaVUE:

User Operations

• User documentations and access
• Creating Basic Connections (port-type, config connect, pass-all, port-params, show connect)
• Define and Apply Port Filters (config filter, port-filter, show filter)
• Stacking: Connections and Filters in a Multi-box Stack (xb commands)
• Filter Mapping in Single and Multi-box Configurations (map, map-rule, mapping, xbmap)
• Port Filters or Filter Mapping, the Benefits of Each
• GigaSTREAM tool port operations
• Verifying Port Connectivity (show connect, show port-stats)

System Configuration and Administration

• Initial IP Settings
• Time and Date Settings (sntp, timezone, daylight savings offset)
• Stacking Configuration (Box ID, Group ID, GigaSTREAM stack ports, active links, star vs daisy chain or combination of both)
• Cascading GigaVUE’s
• When to cascade, when to stack
• Creating and Modifying User Accounts (config user, password, port-locking)
• Authentication Server Settings (hostkey, aaa, Tacacs+ and Radius Server)
• Configuration File Management (config save, upload)
• SNMP Configuration, Traps
• Upgrading GigaVUE Firmware (install command)
• Other system settings (ssh2, banner, rootdis)

Section 6:

Programming the GigaSMART:

Module Configuration and Administration

• User access: port-ownerships, link status controls (Link OAM)
• Architecture: relationship of a GigaSMART in a GV2404; packet flow from a users perspective
• GigaSMART header structure
• Decode support: Wireshark, other tools
• GSOP: packet slicing
• GSOP: packet masking
• GSOP: packet time stamp (methods/protocols supported)
• GSOP: source port tagging

Via CLI and Citrus

Section 7:

Troubleshooting

• Link Connectivity, Status Lights, show port-params Command, Checking for Frame Errors, Optical Power Level, Link state errors
• Fiber tap issues, rolled pair troubleshooting
• Frame Forwarding Issues, show connect, show port-stats, show diag, show port-filter
• Validate a Configuration, watch for errors
• Over-subscription, packet drops, micro-bursts effects
• Filter Problems, Checking Filter Settings, Comparing Ingress and Egress Port Statistics
• Packet distribution issues: filter/map-rule priorities
• GigaVUE Module Effects
• Tool Specific Issue
