To globally disable the MAC move action feature, include the disable-action statement at the [edit protocols l2-learning The global-mac-move statement at the global hierarchy level. Of times a MAC address move occurs in one second. Of time over which the MAC address move occurs, and specified number The number of times a MAC address move occurs, a specified period The router to report a MAC address move based on the following parameters: Or within a different unit of the same physical interface and thisīehavior occurs frequently, it is considered a MAC move. When a MAC address appears on a different physical interface Remains constant regardless of whether the configuration of the interface Or an aggregated Ethernet interface or is not configured as any ofĪn RVI, a VME, or as an aggregated Ethernet interface.įor aggregated Ethernet interfaces, the MAC address assignment Pattern to distinguish between an interface that is configured asĪny of a routed VLAN interface ( RVI), a virtual management Ethernet (VME) interface, The assignmentĭepends on how the interface is configured. Unique identifier as the last group of hexadecimal digits. Then assigns a unique MAC address to each interface by assigning a

On switches that use line cards, this MAC addressing schemeĭifferentiates the Layer 2 interfaces on different line cards in theįor EX Series switches, the first five groups of hexadecimalĭigits are determined when the switch is manufactured. (LACP), and general monitoring functions-can properly function. Helps ensure that functions that require MAC address differentiation-suchĪs redundant trunk groups (RTGs), Link Aggregation Control Protocol The assignment of a unique MAC address to each network interface
The first five groups of hexadecimalĭigits are derived from the switch and are the same for all interfaces With each group separated from the next group by a colon-for To forward and receive traffic, see Understanding Bridging and VLANs on Switches.Ī MAC address comprises six groups of two hexadecimal digits, For additional information on how a network uses MAC addresses Understanding how network traffic is forwarded and received by the MAC address, understanding MAC address assignment is important to Because all Layer 2 traffic decisions are based on an interface’s MAC addresses are used to identify network devices at LayerĢ. Regarding MAC address assignments in a Virtual Chassis, see Understanding MAC Address Assignment Standalone Juniper Networks EX Series Ethernet Switches. This topic describes MAC address assignment for interfaces on DHCPĪlso typically uses MAC addresses when assigning IP addresses to nodes. Of a node using the Address Resolution Protocol (ARP) table. IP networks maintain a mapping between the IP and MAC addresses Whereas IP addresses change when the node moves from one part of the MAC addresses are typically fixed on a per-node basis,

Node, whereas IP addresses apply to the software implementation of The difference is that the MAC addresses apply to a physical or virtual Which runs at Layer 3 (networking and routing).

The second half of a MAC address represents the serial numberĪssigned to the adapter by the manufacturer.Ĭontrast MAC addressing, which works at Layer 2, with IP addressing,
These IDs are regulated by an Internet standardsīody.
The first half of a MAC address contains the ID number of theĪdapter manufacturer. MAC addresses are usually written in one of these formats: A MAC algorithm acceptsĪs input a secret key and an arbitrary-length message to be authenticated,Ī MAC address is a 12-digit hexadecimal number (48 bits in long). That are assigned to all ports on a switch. Identify one another at the data link layer, by using the MAC addresses In Layer 2, multiple devices on the same physical link can uniquely This channel may provide unicast, multicast, The MAC sublayer emulates a full-duplex logical communication channel The MAC sublayer acts as an interface between the logical linkĬontrol (LLC) Ethernet sublayer and Layer 1 (the physical layer). Several terminals or network nodes to communicate in a network. Provides addressing and channel access control mechanisms that enable In Layer 2 of a network, the Media Access Control (MAC) sublayer This topic provides an introduction to the MAC sublayer
