Description

Troubleshooting BIG-IP

Duration: 2 days

Apply bottom-to-top techniques to troubleshoot BIG-IP systems. Review a variety of lower layer tools including ping, bigtop, netstat and tcpdump for manipulating different flags for viewing hex and ASCII.

Analyze network protocols using Wireshark and a variety of capture file formats including pcap and tcpdump. Build filters and use different commands and expressions to capture data on different connections in hands-on lab scenarios. Use the Fiddler HTTP proxy to view and analyze different session elements including URL, Content-Type and other headers, bytes sent/received, response codes, and performance statistics. Explore various curl command options for testing endpoint availability and analyzing ingress and egress payloads in detail.

Learn how to use KDiff to compare files from different BIG-IP devices for locating different traffic processing objects. Gain familiarity with using local and remote logging data, facilities, messaging, and levels for troubleshooting. See how iRules can be used for setting up message logging and logging levels. Finally, learn how to create an analytics profile to view traffic statistics, application visibility, and reporting.

Objectives

At the end of this course, the student will be able to:

    • Describe the role of the BIG-IP system as a full proxy device in an application delivery network
    • Set up, start/restart/stop, license, and provision the BIG-IP system
    • Create a basic network configuration on the BIG-IP system including VLANs and self IPs
    • Use the Configuration utility and TMOS Shell (tmsh) to manage BIG-IP resources and use as a resource when troubleshooting
    • Create, restore from, and manage BIG-IP archives
    • Understand and implement troubleshooting methodology to find and resolve issues
    • View resource status, availability, and statistical information and use this information to determine how the BIG-IP system is currently processing traffic
    • Use iApps to update BIG-IP configuration
    • Perform troubleshooting and problem determination activities including using the iHealth diagnostic tool, researching known issues and solutions on AskF5, submitting a problem ticket to F5 Technical Support, and view traffic flow using tcpdump
    • Understand the tools (ping, netstat, tcpdump, ssldump, WireShark, diff, Kdiff3, Fiddler, BIG-IP logs, etc.) available to use to identify BIG-IP and network issues from bottom to top
    • List log files available, understand log levels, and use the appropriate files, log levels, and filters for troubleshooting
    • Use High Speed Logging (HSL) and SNMP trap implementations to perform troubleshooting and problem determination activities
    • Describe the role of iRules in affecting traffic behavior and how to use them to aid with troubleshooting and problem determination

 

Audience

This course is intended for network administrators responsible for managing the normal day-to-day operation and administration of a BIG-IP application delivery network. This course presents the prerequisite knowledge for many of F5’s other BIG-IP instructor-led training courses.

Prerequisites

Students must complete one of the following F5 prerequisites before attending this course:

Suggested Prework

The following free Self-Directed Training (SDT) courses, although optional, are helpful for any student with limited BIG-IP administration and configuration experience:

  • Getting Started with BIG-IP
  • Getting Started with Local Traffic Manager (LTM)
  • General network technology knowledge and experience are recommended before attending any F5 Global Training Services instructor-led course, including OSI model encapsulation, routing and switching, Ethernet and ARP, TCP/IP concepts, IP addressing and subnetting, NAT and private IP addressing, NAT and private IP addressing, default gateway, network firewalls, and LAN vs. WAN.

    Students should be familiar with and be able to configure basic BIG-IP elements such as virtual servers, pools, pool members, and nodes, pool monitors, and basic virtual server profiles. In addition, students should be familiar with the basics of the Linux command line, and have solid understanding of Layer 2 Ethernet and ARP networking, Layer 3 and 4 TCP/IP networking, including IP addressing and subnetting, Layer 7 HTTP networking, and HTML.

    The following course-specific knowledge and experience is suggested before attending this course:

    • Web application delivery
    • HTTP, HTTPS, FTP and SSH protocols
    • TLS/SSL
