Appendix 1. External Software Packages
This appendix discusses several of the external software packages that we discussed throughout the book. Because this is primarily a Cisco book, which is not focused on any particular software products, we have restricted ourselves to only software that is freely distributed. There are also commercial products that fulfill the same functions as some of these packages, particularly for SNMP, if you prefer to use them.
