Suppose to have two host (192.168.0.4, 192.168.0.6) and you would find the layer2 path using the Ciscozine-SW1 Switch.īelow the MAC address table and the ARP table of the Ciscozine-SW1 switch: Ciscozine-SW1#sh mac-address-table dynamic See you the example to understand how this feature works. If you specify source and destination addresses that belong to different VLANs, the Layer 2 path is not identified, and an error message appears. The traceroute mac command output shows the Layer2 path when the specified source and destination addresses belong to the same VLAN. To do it, Cisco has implemented a good tool: traceroute mac. In a Data Center, it is often required to find a host and the layer2 path. Routers decrement this parameter and discard a packet when the TTL value has reached zero, returning an ICMP error message (ICMP Time Exceeded) to the sender.

Tracing the intermediate routers traversed involves control of the time-to-live (TTL) Internet Protocol parameter. Traceroute sends a sequence of Internet Control Message Protocol (ICMP) packets addressed to a destination host.

This example shows how to display the MAC address table: switch# show mac-address-table VLAN MAC Address Type Age Port -+-+-+-+- 1 0018.b967.3cd0 dynamic 10 Eth1/3 1 is a tool for measuring the route path and transit times of packets across an Internet Protocol (IP) network. Switch# show mac-address-table aging-timeĭisplays the MAC address aging time for all VLANS defined in the switch.ĭisplays the contents of the MAC address table. To display MAC address configuration information, perform one of these tasks: This example shows how to clear the dynamic entries in the MAC address table: switch# clear mac-address-table dynamic Verifying the MAC Address Configuration Switch(config-)# mac-address-table static mac_address vlan vlan-id Ĭlears the dynamic address entries from the MAC address table. To configure a static MAC address, perform this task: Note You can also configure a static MAC address in interface configuration mode or VLAN configuration mode. These addresses are static MAC addresses. You can configure MAC addresses for the switch.

You can also enter a MAC address, which is termed a static MAC address, into the table. The switch then forwards subsequent frames to a single LAN port without flooding all LAN ports. When the destination station replies, the switch adds its relevant MAC source address and port ID to the address table. When the switch receives a frame for a MAC destination address not listed in its address table, it floods the frame to all LAN ports of the same VLAN except the port that received the frame. The switch dynamically builds the address table by using the MAC source address of the frames received. When the switch receives a frame, it associates the media access control (MAC) address of the sending network device with the LAN port on which it was received. To switch frames between LAN ports efficiently, the switch maintains an address table.
