Config Lab CCNA Vol 2 Part 3
Config Lab: Interface PAT 1
PAT – Port Address Translation – plays a huge role in IPv4 networks. Today’s post looks at the simpler of the two configuration options for router NAT configuration: a single router interface IP address as in the inside global address.
Config Lab: Dynamic NAT 1
Dynamic NAT – specifically, dynamic NAT without also doing PAT – creates a 1-to-1 mapping between an inside local address and an inside global address. Unlike static NAT, however, dynamic NAT does not pre-determine the specific IP addresses to map.
Config Lab: Static NAT 1
Static NAT matches a single inside local address with a single inside global address. It does not conserve addresses, but it does let you make a server reachable to external devices with a permanent address to use with the static
Config Lab: Syslog 3
When first starting out with Cisco routers and switches, log messages are those irritating messages that show up to interrupt us from the current task at hand. Over time, most of us find those messages more and more useful. Eventually,
Config Lab: Syslog 2
Most of us skim through descriptions of Syslog messages and message levels. This lab helps you slow down just a bit with a configuration exercise that makes you remember message severity levels and how to configure them. As usual, the
Config Lab: Syslog 1
Routers and switches issue log messages to tell us about different events. Be ready to run through the various options! Today’s lab exercises a couple of those options related to message formats and how a router chooses to manage Syslog
Config Lab: NTP Client/Server
NTP makes me think of old spy novels and movies, where the team would set their analog watches to the same time, and say something like “On my mark, it will be 9:55… mark!”. NTP uses other mechanisms, of course,
Config Lab: CDP/LLDP 1
#CDP has long been the default and favored protocol for a variety of device discovery functions, but LLDP offers an alternative as well. (LLDP is new to the exam topics per the May 2016 new CCENT and CCNA R&S exams.)
Answers: Basic SNMP Config 1
Can you configure SNMP version 2C without looking up the commands? Can you secure it with what effectively acts like passwords? You know the drill: go try the original lab exercise first, and then come back here to check your
