Know what a network baseline is and the major components that go into making it. A
baseline is a set of documentation that establishes normal operating conditions on the network.
Some of the key components of a baseline are the network configuration tables, the
network topology diagrams, the end-system configuration tables, and the end-system topology
diagrams.
Know what network configuration tables are and the information they contain. Network
configuration tables are used to record key settings of network devices, as well as other related
information. Some common items included in a network configuration table are device name,
flash information, DRAM, IOS/CatOS, interface number, MAC address, speed, duplex,
VLANs, trunking, IP address, subnet, subnet mask, and routing protocol.
Know what network topology diagrams are and the information they contain. Network
topology diagrams are graphical representations of the network; they are usually built from
many of the same components as the network configuration tables. Some common components
of network topology diagrams are device name, connections between devices, interface name,
VLANs, trunking, IP address, subnet mask, and routing protocols. 1064
