Identifying Network Components
Understanding network
infrastructure and network management is the first step in venturing to assess
and manage application performance over the network. If you do not know how your
network is designed and implemented, you will not be in a position to
effectively monitor and manage your network or the applications that use it.
Take the time to understand your network topology, and be sure to become
familiar with each component, including the following:
-
The make and model of routers,
switches, firewalls, server load-balancers, and other network elements currently
in use at each location.
-
The version of operating system and
licensed features that are in use on each of the network elements.
-
The interface number and
type, as well as any assigned IP address information of each interface and
node.
-
The interface configuration,
including speed and duplex. Interfaces should either negotiate properly with the
peer device or be hard-coded to the correct configuration to ensure
consistency.
