User guide

From the Smartports window, you can see which Smartports role is applied to each port. Move the pointer
over a port to display its port number, Smartports role, and VLAN ID (VLAN membership).
Before you use Smartports, decide which switch port you intent to connect to which device type. You can
apply a Smartports role to a specific port or to all ports on the switch.
Restrictions
We recommend that you do not change specific port settings after you enable a Smartports role on a
port. Any port setting changes can alter the effectiveness of the Smartports role.
•
Do not apply the Desktop role to ports that are connected to switches, routers, or APs.•
The Smartport role Switch automatically enables 802.1Q trunking on the port. If a remote switch does
not support 802.1Q trunking or the trunking is manually turned off, the spanning tree state of the port
on the remote switch goes to blocking for type inconsistency. If the remote switch is the root bridge,
the switch port does not go to blocking mode. In this case, the switch port trunk status is ON at both
ends of the switches, but there is not any communication between the switches through these ports.
There are no diagnostic messages displayed on the Catalyst Express 500 device.
