Port CPU

[jahilnt10]

While finding a mac port, I got this result, what does mean by port CPU?

Switch#show mac-address-table address 000a.8afa.cf80

Mac Address Table

Vlan Mac Address Type Ports

---- ----------- ---- -----

All 000a.8afa.cf80 STATIC CPU

Total Mac Addresses for this criterion: 1

Port CPU mean, that the mac-address is assigned by CPU and is an internal allocation for some internal process. Every switch has a pool of mac-addreses for internal allocation for its processes.For example, for STP process, VTP process, switch assings the internal mac-addresses.
