General diagnostic tools

Wireless Management System

The Wireless Management System (WMS) is a web-based interface that you can use to plan,
configure, deploy, and monitor a WLAN and its users.
Access control for WMS users is classified based on the following predefined roles:
• Security Administrator: Has full access control and can create users, delete users, and
set permissions.
• Configuration Administrator: Has privileges to define and apply configurations but does
not have access control and user creation privileges.
• Monitoring User: Only has monitoring privileges. Does not have configuration or access
control privileges.

Health Checks

The Health Check is a diagnostic tool used to verify the overall health of the system. The tests
verify that the system is ready for operations and report any problems that can affect the
systems operational stability. The tester can select which test to run and can schedule the test.
Each component tested shows inventory information and status of the component (actual level,
threshold/limit and good/bad indicator). This tool helps customers and partners verify that the
product is functioning within defined normal operational limits.

Virtual link aggregation control protocol

Virtual link aggregation control protocol (VLACP) is a Layer 2 handshaking protocol providing
end-to-end failure detection between two physical Ethernet interfaces. This protocp; allows the
switch to detect unidirectional or bidirectional link failures.
With VLACP, far-end failures can be detected allowing multilink trunks (MLT) to fail over
properly when end-to-end connectivity is not guaranteed for certain links in an aggregation
group.
VLACP is configured for each port. The port can be an individual port or member of MLT. For
proper VLACP operation there must be a logical point to point connection (L2 tunnel) between
two endpoints. VLACP does not work for point-to-multipoint connections. On VLACP enabled
ports, VLACPDUs are sent periodically. If PDUs are not received on a particular link, that link
is taken down after a configurable timeout period. The destination MAC address is also
configurable.
