Troubleshooting Router Connections

Troubleshooting PIX and ASA Connections

This chapter will focus on how to troubleshoot IPsec sessions on Cisco PIX and ASA security appliances. The layout of this chapter is similar to that found in Chapter 19, "Troubleshooting Router Connections." I've broken the chapter into two areas on troubleshooting: ISAKMP/IKE Phase 1 and ISAKMP/IKE Phase 2 issues. With these two areas, I'll show you how ISAKMP/IKE Phase 1 and 2 connections are built, and what to look for when there is a problem with either of these phases.

This chapter by no means covers all possible problems you'll experience with IPsec sessions on Cisco security appliances. However, I hope to provide you with the basic background knowledge so that troubleshooting IPsec sessions on the appliances is a simpler process.
