Cisco Mac Address Table Learning Feature - Muslipass Starting with cisco nx os release 7.2(0)n1(1), the rmac learning feature is supported on cisco nexus 5600 and 6000 series switches. this feature allows the default mac address (rmac) of a vlan interface to be dynamically learned on another vlan over a bridged interface on the switch. A switch can learn mac addresses in two ways; statically or dynamically. in the static option, we manually add mac addresses to the cam table. in the dynamic option, the switch automatically learns and adds mac addresses to the cam table. adding mac addresses to the cam table is a tedious task.

When you enter this command, the interface converts all the dynamic secure mac addresses, including those that were dynamically learned before sticky learning was enabled, to sticky secure mac addresses. So, as an example, we should at least know that host's ip address and ping it, so that the switch learns its mac through the host's echo reply. now, on my case where the show interface showed the port as "up/up" but no mac address was learnt on that port: it is the wake on lan (wol) feature. Check mac address and arp tables switches forward traffic based on mac addresses. you may need to confirm that the switch is learning addresses correctly. to see all mac addresses learned and which ports they are on, use this: show mac address table to see only learned (not manually added) mac addresses, use this: show mac address table dynamic.

This doc explains about the switch learning the mac address of the another switch's interface. example: switch1#sh macaddress table mac address table vlan mac address type ports 1 0001.4311.cd4d dynamic fa0/1 1 0002.1714.ed24 dynamic fa0/2 1 000b.be37.3902 dynamic fa0/2. This document describes a specific situation where the upstream gateway mac address was unexpectedly learned on random access interfaces. the details are based on tac cases solved by tac engineers working in partnership with customer teams. Cisco cpt configuration guide–ctc and documentation release 9.5.x and cisco ios release 15.2(01) 78 20603 05 17 configuring mac learning dlp j27 display information about the mac address table using cisco ios commands. Catalyst switches learn mac addresses on switch ports based on the source mac address (smac) of an inbound frame. the mac address table is typically a trustworthy source of information that guides a network engineer towards the location of a given address.
