Chapter 5: General diagnostic tools

The WLAN 8100 series device has diagnostic features available with the CLI and WMS, a Web interface.
You can use these diagnostic tools to help you troubleshoot operational and configuration issues. You can
configure and display files, view and monitor port statistics, trace a route, run loopback and ping tests,
test the switch fabric, and view the address resolution table.
You can access the CLI through either a direct console connection to the switch or by using the Telnet or
SSH protocols to connect to the switch remotely.
You can use the WMS in cases where the troubleshooting steps require corroborating information to
ensure diagnosis.

CLI command modes

The CLI has five major command modes. Each mode supports a specific set of commands.
The command set of a higher privilege mode is a superset of a lower privilege mode. That is,
all lower privilege mode commands are accessible when using a higher privilege mode.
The command modes are as follows:
• User EXEC mode: The User EXEC mode (also referred to as exec mode) is the default
CLI command mode. User EXEC is the initial mode of access when the switch is first
turned on. User EXEC mode provides a limited subset of CLI commands. This mode is
the most restrictive CLI mode and supports few commands.
• Privileged EXEC mode: The Privileged EXEC mode (also referred to as privExec mode)
enables you to perform basic switch-level management tasks, such as downloading
software images, setting passwords, and booting the switch. Privileged EXEC mode is
an unrestricted mode that allows you to view all settings on the switch, and if you are
logged in with write access, it also allows you to access all configuration modes and
commands that affect operation of the switch (such as downloading images and
rebooting).
• Global configuration mode: The Global Configuration mode (also referred to as config
mode) enables you to set and display general configurations for the switch such as IP
address, SNMP parameters, Telnet access, and VLANs.
• Interface configuration mode: The Interface Configuration mode (also referred to as
config-if mode) enables you to configure parameters for each port or VLAN, such as
speed, duplex mode, and rate-limiting.
• Router configuration mode: The Router Configuration mode (also referred to as config-
router mode) enables you to configure routing parameters for RIP, OSPF, and VRRP.
