Cisco show mac address attached to port
Can you check with the command show mac-address-table command on the edge swithch On a Cisco switch, you can issue the "sh cam dcbd" command. The output is too wide to include in this reply If the port that is reported is a trunked port, then the MAC is on another switch.

Although your original port is over a year old, I hope this still helps you. I am not sure of the model of the switch you are referring too however, on the the command is sh mac add add enter the mac add you are looking for. Tech Sign In Page. Forgot Password?

Something went wrong on our end. Please try again later. Sometimes this information is limited to MAC address es only, and sometimes it can be very detailed depending on the specific configuration of the connected device. Most of these programs take advantage of the Simple Network Management Protocol SNMP and its query mechanisms and some even provide the ability to alter switchport status and configuration if needed. Here are some of the most noteworthy products.

Management Switch Port Mapping Tool, along with NetDB mentioned next , are the only two packages that were stand-alone and specific to switch port mapping. Network Tracking Database NetDB — The Network Tracking Database tool is an open-source Linux-based tool that can be used along with a web server engine to scan the switches on a network and record information into a database. While this tool does require some amount of Linux CLI knowledge, it is free and, as it is open source, it can be modified to meet the exact needs of the user.
Most of the information that is base information that can be retrieved is similar to that of the Management Switch Port Mapping Tool mentioned above but in a less easy-to-look-at format. NetDB, along with the Management Switch Port Mapping Tool, are the only two packages that were stand-alone and specific to switchport mapping. It provides a number of different features that can help with the management of a network, including IP address management, switch port management SNMP , device configuration management, and bandwidth monitoring, as well as several networking tools that can be used to monitor and troubleshoot the network.
While the OpUtils interface is cleaner and more graphical than the previous two options, it also is lacking in its full support of CDP and LLDP, both which can provide network discovery enhancement. A free version of OpUtils exists with some limited functionality. Lansweeper — The Lansweeper package is focused on network inventory and provides a number of different functionalities that make the management of all network elements across the network much easier, including support for everything from printers to servers.
The real question is what the specific purpose of the tool is: If the main purpose is to get as much information about those devices connected to a switch as possible, then Lansweeper may come up light.

While all of the tools referenced above have their specific advantages and disadvantages, one thing that is constant: All of them query information from the switching device itself, either through SNMP or the CLI. Almost all of the information that is displayed in these programs can be found from the CLI at least on Cisco equipment. While there are security concerns that come with the use of CDP, its benefits for network discovery cannot be challenged.
It provides an easy mechanism that provides a list of connected CDP supported devices, their capabilities and how they are connected.
Generally speaking CDP is supported on only Cisco devices and a few other supporting devices. However, like CDP there are some inherent security concerns for its use globally. The information from the ARP table can be displayed and used to determine those devices connected off a specific interface. Keep in mind, however, that the ARP table will only show those devices that have transmitted traffic recently within four hours.
The caveat to using this table for mapping is that it only populates when traffic is received from a device, and it is only kept within the table for five minutes from the last seen transmission.
