Using the 'mac-address sticky' option you will reduce efforts for managing mac address table on each port, while 'mac-address maximum 2' will grant that no more than 2 MAC addresses can be applied on that port.

Once someone asks you to disable a device, you can match the IP address with its MAC address and disable the port you need.ДЄlso you can prevent users from 'sniffing' the network by using the 'protected port' feature given by Cisco Catalysts. To find out if your switch supports this feature take a look at the Cisco. I would suggest you to do a map of the layer 2 of your network using some simple tool (nmap with -sP option to do a ping sweep of the entire subnet) and gathering the whole information in an Excel file (or equivalent). Cisco Nexus 93108tc-ex 48 Ports Manageable Layer 3 Switch 48 Network 6 Expa. VACL capture works with most of the newer Cisco switches including the 6500, 4500, 4900, 3750E, 3750, 3560E, and the 3560. Also, from a security point of view, a portscan action can be done using a spoofed IP address, so the information given is unreliable.

This includes the product id, serial number supported speed and diagnostic information about the SFP. If you are planning to have only one network in your whole switch (for example, 10.10.192.0). Display the transceiver (SFP) information on all the ports. While these commands were tested on a cisco catalyst switch 3750 series, similar commands (may be with slight variation to the port number format) should work on all cisco switches. Show the trunks on vsan 100 in port-channel 1. Since the switch is working at Layer 2 of the OSI model, you cannot associate an IP address on a port, but only a MAC address and the port it is connected. show interface port-channel 1 trunk vsan 100.
