This commands shows, for the specified ports, the aliases discovered using the Node Alias feature (MAC address, alias ID, time last learned, VID, protocol, and source IP address). Node Alias discovers information about the end systems on a per-port basis. Information from packets from end systems are captured in a database that can be queried.
| nodealias | Node Alias feature that maps source IP address, MAC address, host name, and protocol on a per port basis. |
| ports | Specifies information on the ports for the Node Alias feature. |
| port_list | Specifies for which ports to display information. Designated as a port list separated by comma (,) or dash (-). |
| all | (Default) Specifies showing Node Alias information for all ports. |
If the ports are not specified, information appears for all ports.
The following example shows Node Alias information for port 10:
