TWO-MINUTE DRILL
2960 Overview
❑ The 2960 switches support Fast Ethernet and/or Gigabit Ethernet interfaces.
❑ The SYSTEM LED will be amber if the switch experiences a malfunction.
❑ The MODE button is used to change the meanings of the port LEDs.
❑ If a port LED is flashing amber/green, there is an operational problem with
the port; if it is amber, the port has been disabled: shutdown, STP blocking,
or port security violation.
Switch Startup
❑ When a switch boots up, POST is run, the IOS is found and loaded, and the
configuration is found and loaded.
❑ If a configuration file cannot be found when booting up, the System
Configuration Dialog questions can be answered to place a basic
configuration on the switch.
Basic Switch Configuration
❑ An IP address can be assigned to a VLAN interface on a switch for accessing
it remotely via telnet or SSH, or to back up its configuration or upgrade its
IOS using the ip address command.
❑ The ip default-gateway command assigns a router address the switch
should use to access other subnets.
Basic Switch Operation and Verification
❑ The show mac-address-table command displays the port address
table of the switch.
Port Security Feature
❑ Port security is used to prevent unauthorized access to a LAN on access
interfaces (non-trunk connections).
❑ The switchport port-security commands are used to configure it.
