So i used it, and it replied with many IP connect at vitual interface I also have the Cisco Press CCNA Flashcards book also, and that only mentions the first command above. show mac-address-table & show mac address-table. Noalias Display IP address instead of alias hostname I have the Wendell Odom study books for INCD1 & 2, and have seen the show mac address table command in two formats. Consider the following example: SW1show interfaces fa0/1 FastEthernet0/1 is up, line protocol is up (connected) Hardware is Lance, address is 0040.0b21.0b01 (bia 0040.0b21. A loopback interface can also be used to establish a Telnet session from the console port of the device to its auxiliary port when all other interfaces are down. You can also configure the loopback address as the Router ID for routing protocols like OSPF and BGP. Mlsrp Show cam Multilayer Switching Router infoĪnd it reply with physical port that connect to 2912 switch The status of an interface on a Cisco switch can be checked using the show interface TYPE exec mode command.

Īnyway i've tried all command for every switch & router will summarize as the following. (^ - ^bb)Īnyway just in case you want to know the story. now i know already that the list of IP address that i got after do 'sh arp' at core router has only 1 IP that can ping so the thing that connects to the switch port is that one. For Cisco Routers, The MAC address can be seen using the show interface command.
