Configuring User Network and Network Node Interfaces

By default, all the 10/100 ports on the Cisco ME switch are configured as UNIs, and the SFP module
ports are configured as NNIs.
You can use the port-type interface configuration command to change the port types. At any one time,
only four ports on the switch can be configured as NNIs, but every port on the switch can be configured
as UNIs.
When a port is changed from an NNI to a UNI, it inherits the configuration of the assigned VLAN, either
in isolated or community mode. For more information about configuring UNI isolated and UNI
community VLANs, see
When you change a port from NNI to UNI or the reverse, any features exclusive to the port type are
Note
removed from the configuration to prevent conflicting configuration options on a specific interface type.
