MAC address limit is a security mechanism that can be used to restrict the number of MAC addresses to be learnt by an interface or a Virtual Switch Instance (VSI). MAC address limit minimizes the impact of an attack and protects other users.
MAC entries on the Layer 2 network are essential to forwarding packets. When MAC attacks are launched on a network, MAC entries are exhausted by invalid MAC addresses, denying access of authorized users to the network. To prevent this problem, you can configure MAC address limit to minimize the impact of MAC attacks.
MAC address limit offers the following benefits to carriers:
Configures the maximum number of MAC addresses to be learnt by an interface or a Virtual Switch Instance (VSI) to minimize the impact of an attack and protect other users.
MAC address limit offers the following benefits to users:
Minimizes the impact of attacks so that the security of users is enhanced and the bandwidth usage is improved.
