Link fault. Error frames can affect connectivity, and errors such as
excessive collisions, CRC errors, and alignment and jabber errors
are monitored for a link-fault indication.
Solid amber Port is not forwarding. Port was disabled by management or an
address violation or was blocked by Spanning Tree Protocol (STP).
Note After a port is reconfigured, the port LED can remain
amber for up to 30 seconds as STP checks the switch for
possible loops.
UTL
(utilization)
Green The LEDs display backplane utilization on a logarithmic scale.
If all port LEDs are green, the switch is using 50 percent or more
of its total bandwidth capacity. If the right-most LED is amber, the
switch is using less than 50 percent of its total bandwidth. If the
LED to the left of the right-most LED is amber, the switch is using
less than 25 percent of its total capacity, and so on.
See Figure 1-7 for details.
