What is a cisco switch mac#
If you want one particular switch to be the Root Bridge (Switch), change the priority to a lower value than 32,768. The easiest way to see which Ethernet MAC address is on which port is to use the show mac-address-table command. Here Switch 1 is the Root Bridge (Switch) since it has the lowest MAC address. The following example shows four switches with default priority value. If all the Switches in your Local Area Network (LAN) are configured with the default Switch Priority (32,768), the Switch MAC address will become the decisive factor in electing the Root Bridge (Switch).The Bridge (Switch) with the lowest MAC Adress is then elected as Root Bridge (Switch). The term refers to a ports ability to connect to devices (like APs) that require more than 1 gig of throughput. The Switch Priority, which is a numerical value defined by IEEE 802.1D, which is equal to 32,768 by default. What is Cisco Multigigabit and Why Should I Care - The main benefit to Multigigabit is that its for switches that have the latest/greatest 802.11ac Wave 2 wireless APs connected to them.The Bridge (Switch) priority value is used to find the Bridge (Swtich) ID.
