Now, log onto the Access switch and do a "show mac-adddress-table" command for the MAC address and that should show the interface to which it is connectedĪccess1# show mac-address-table 0000.1111.1111Īs you can see which port the device is connected and on which switch. That tells you, it is the Access switch 1 that is connected to Te1/1 and not the device itself. S – Switch, H – Host, I – IGMP, r – Repeater, P – Phoneĭevice ID Local Intrfce Holdtme Capability Platform Port IDĪccess1 Ten 1/1 129 R S I WS-C6509 Ten 1/1 Now, do a "show cdp neighbors" to show the directly connected devices.Ĭapability Codes: R – Router, T – Trans Bridge, B – Source Route Bridge This shows the ports Te1/1 or Te2/1 as a source through which the address is learnt. U – in use f – failed to allocate aggregator So do a "show etherchannel" command to find the phsycial ports that are paired.įlags: D – down P – bundled in port-channel This indicates that there is a etherchannelis being setup.
Sometimes, the output might show as follows Looking at this, it is very likely that this is a uplink (TenGigabit Ethernet link) to another Distribution or Access switch. This indicates that the device is either connected to the port or though another switch which is connected to the interface. This will show the interface to which it is connected or through which it is learned.Ĭore1# sh mac-address-table address 0000.1111.1111 Now, do a show mac-address command on the core switch or router. Internet 192.168.1.15 22 0000.1111.1111 ARPA Vlan1įrom the above you know the MAC Address of for the device:
Protocol Address Age (min) Hardware Addr Type Interface If yes, then simply logon to one of your core switches or routers and do a simple sh ip arp If you have an IP address on hand quickly ping and check if the device is pingable. This is not a difficult task but can certainly be time consuming.

Then, ‘transport input ssh’ and ‘login local’ commands are executed for the successful configuration of SSH on the Cisco Router.If you have a big network with multiple Access Switches connecting to the core switches or routers then tracing a device like a PC or a laptop for troubleshooting or security purposes is one of those tasks that you often end up doing. Further, ‘line vty 0 15’ is executed, so that router can be accessed from a remote system connected to the network. ‘IP ssh version 2’ command is used to define the version of SSH, which will be configured on this router. Further, the ‘username password’ command is used to set the username to establish an SSH connection with the network device. #How to check mac address on cisco switch password
‘enable password password’ command is executed to maintain security and to allow only authorized users to access the router command-line interface. A value of ‘1024’ is input and enter is clicked to successfully generate the key. Then, to maintain a secure SSH connection, a crypto key is generated using ‘crypto key generate RSA’ command. At first, domain name is set using ‘ip domain-name domain-name command. All the commands used to enable the SSH is highlighted in the below-provided screen-grab of the Cisco Packet Tracer. In addition to this, syntax and explanation of each command are provided along with screen-grabs.īelow listed steps will be followed to configure the SSH as follows.Ĭisco Packet Tracer is opened and network topology is created between a computer system and a router.ĭesktop settings of the Computer System need to be accessed to assign it with IP address, associated subnet mask and gateway address of the network.Īn IP address is assigned to Router’s interface To learn about the SSH configuration, the Cisco Packet Tracer tool is used to demonstrate the steps to be followed and associated commands to be executed for this purpose. The primary aim to configure SSH is to access devices deployed in a network from a remote location so that the required configuration can be performed and resources can be provided in a seamless manner. SSH is a security mechanism, which can be used to access the privilege and configuration mode of a Router and a Switch from a remote location to perform the required action.
