Avoid Smartports Mismatches
A Smartports mismatch occurs when an attached device does not match the port
role applied to the switch port. Mismatches can have adverse effects on devices
and your network.
Mismatches can have these results:
• Affect the behavior of the attached device
• Lower network performance, for example reduce the level of 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 port role is applied to a port before
attaching a device to the port or reconnecting devices that have been moved.
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.
This role prioritizes voice traffic over general data traffic to ensure 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 up to 30 mobile
(wireless) users.
Multiport Automation Device Apply this role to ports connected to multiport EtherNet/IP devices, such as multiport EtherNet/IP devices arranged in a linear or daisy
chain topology, the 1783-ETAP module (for connection to the device port only), unmanaged switches (such as the Stratix 2000™) and
managed switches with Remote Spanning Tree Protocol (RSTP) disabled:
• Port is set to Access mode.
• No port security.
• Optimized queue management for CIP traffic.
Virtual Desktop for Automation Apply this role to ports connected to computers running virtualization software. This can be used with devices running up to two MAC
addresses:
• Port is set to Access mode.
• Portfast is enabled.
• Port security supports two MAC IDs.
IMPORTANT: Do not apply the Virtual Desktop for Automation role to ports that are connected to switches, routers, or access points.
Port Mirroring Apply this role to ports to be monitored by a network analyzer. For more information about port mirroring, see Port Mirroring on page 82 .
None Apply this role to ports if you do not want a specialized port role on the port. This role can be used on connections to any device, including
devices in the roles described above.
