This blog was originally started to better help me understand the technologies in the CCIE R&S blueprint; after completing the R&S track I have decided to transition the blog into a technology blog.

CCIE #29033

This blog will continue to include questions, troubleshooting scenarios, and references to existing and new technologies but will grow to include a variety of different platforms and technologies. Currently I have created over 185 questions/answers in regards to the CCIE R&S track!! Note: answers are in the comment field or within "Read More" section.

snmpv1 - Initial implementation, authentication is based on community string only

snmpv2 - increased performance, security, confidentiality, and manager-to-manager communications. It introduced GetBulkRequest. Incompatible with version 1

snmpv2c - provides the same functions as version 2 with backward capability with version 1

snmpv3 - provides important security features confidentiality, integrity, authentication

Version 2c example:

community string of RESTRICT with read/write capability for host 192.168.1.10 enabling all traps

config#snmp-server community RESTRICT rw 10
config#access-list 10 permit 192.168.1.10
config#snmp-server enable traps
