Simple Network Management Protocol (SNMP) | 197Use dot3aCurAggFdbTable to fetch the learned MAC address of a port-channel. The instance number isthe decimal conversion of the MAC address concatenated with the port-channel number.Figure 16-10. Fetching Dynamic MAC Addresses on the Default VLANDeriving Interface IndicesFTOS assigns an interface number to each (configured or unconfigured) physical and logical interface.Display the interface index number using the command show interface from EXEC Privilege mode, asshown in Figure 16-11.Figure 16-11. Display the Interface Index NumberThe interface index is a binary number with bits that indicate the slot number, port number, interface type,and card type of the interface. FTOS converts this binary index number to decimal, and displays it in theoutput of the show interface command.Figure 16-12.
