Avoid Smartport Mismatches
A Smartport mismatch occurs when an attached device does not match the
Smartport role applied to the switch port. Mismatches can have adverse effects on
devices and your network.
Mismatches can result in the following conditions:
• Affect the behavior of the attached device
• Lower network performance (reduce the level of quality of service [QoS])
on CIP, voice, wireless, switch, and router traffic
• Reduce restrictions on guest access to the network
• Reduce protection from denial of service (DoS) attacks on the network
• Disable or shut down the port
We recommend that you always verify which Smartport role is applied to a port
before attaching a device to the port or reconnecting devices.
Phone for Automation
Apply this role to ports to be connected to IP phones. A desktop device, such as a computer, can be connected to the IP
phone. Both the IP phone and the connected computer have network access through the port:
• Port is set to Trunk mode.
• Port security supports three MAC IDs to this port.
This role prioritizes voice traffic over general data traffic to provide clear voice reception on the IP phones.
Wireless for Automation
Apply this role to ports to be connected to wireless access points. The access point can provide network access to as
many as 30 wireless users.
Port Mirroring
Apply this role to ports to be monitored by a network analyzer. For more information about port mirroring, see
.
None
Apply this role to ports if you do not want a specialized Smartport role on the port. This role can be used on connections
to any device, including devices in the roles described above.
CS1…CS10
Custom Smartport roles. You can create a customized port role with a user-defined name. Refer to
the Switch via the Device Manager Web Interface
, for more information on creating custom Smartport roles.
