After some time and after connecting on all Switchs from my computer to manage it, if I go to console on switch C and so this: 'display mac-address mac', I got all mac-address learned from other switchs, including my computer MAC.all saying that is know from port 1 (link port). With this, I can't find where my MAc is connected. The switch would receive the frame and create a new entry in its MAC address table for the server's MAC address (Server - Fa0/2). It would then perform a lookup of its MAC address table to determine whether it knows which port to send the server's traffic to; in this case it does, so it sends the return traffic out only its Fa0/3 port (PC1. The highest MAC address of all the ports in the switch the lowest MAC address of all the ports in the switch the VTP revision number. Refer to the exhibit. CCNA 2 v7.0 Modules 5 – 6 Exam Answers p16. Which switch will be the root bridge after the election process is complete? It depends on the switch model, but on an IOS based switch the command is show mac address-table address xxxx.xxxx.xxxx. You can easily use Excel to map the ports that have MAC addresses found in show mac address-table to the IPs that match the MAC addresses from show ip arp. Based on your network topology, go to the next switch and see what ports that MAC address was learned on there. Note if the port is higher or lower than the previous one, and normally if it's one of the highest numbered ports on the switch, that switch isn't directly linked to that MAC address and has instead learned it from another switch.

Listing all learned MAC addresses on the switch, with the port number on which each MAC address was learned

Listing all learned MAC addresses on one or more ports, with their corresponding port numbers

For example, to list the learned MAC address on ports A1 through A4 and port A6:

Listing all learned MAC addresses on a VLAN, with their port numbers

This command lists the MAC addresses associated with the ports for a given VLAN. For example:

Finding the port on which the switch learned a specific MAC address

For example, to find the port on which the switch learns a MAC address of 080009-21ae84:

This feature lets you determine which switch port on a selected VLAN is being used to communicate with a specific device on the network.

Mac Address For Switch Ports Gigabit

From the Main Menu, select:

1. Status and Counters ...

1. The switch then prompts you to select a VLAN.

2. Use the Space bar to select the VLAN you want, and then press [Enter].

   The switch then displays the MAC address table for that VLAN (Example of the address table.)

   Example of the address table

   To page through the listing, use N and P.

Mac Address For Switch Ports Configuration

This feature uses a device's MAC address that you enter to identify the port used by that device.

1. Proceeding from Example of the address table, press [S] (for S), to display the following prompt:

2. Enter the MAC address you want to locate and press [Enter].

   The address and port number are highlighted if found (Example of menu indicating located MAC address.) If the switch does not find the MAC address on the currently selected VLAN, it leaves the MAC address listing empty.

   Example of menu indicating located MAC address

3. Press [P] (for P) to return to the full address table listing.

This feature displays and searches for MAC addresses on the specified port instead of for all ports on the switch.

1. From the Main Menu, select:

   Listing MAC addresses for a specific port

2. Use the Space bar to select the port you want to list or search for MAC addresses, then press [Enter] to list the MAC addresses detected on that port.

Switch Mac Address Table

Proceeding from step 2, above:

Get Mac Address Of Switch

1. Press [S] (for Search), to display the following prompt:

2. Enter the MAC address you want to locate and press [Enter].

   The address is highlighted if found. If the switch does not find the address, it leaves the MAC address listing empty.

3. Press [P] (for P) to return to the previous per-port listing.
