Pre-configuration TasksД«efore configuring a bridge domain-based MAC address table, create a bridge domain. Static and static blackhole MAC address entriesД¬an overwrite dynamic MAC address entries, but cannot be overwrittenД«y dynamic MAC address entries. Manually configured MAC address entries take precedence overДynamically generated entries.

Dynamically learned MAC addressesДЄre deleted if they are not updated after the specified aging time Prevent a MAC address table overflow, an aging time can be set forДynamically learned MAC address entries. Network topology changes, devices keep learning MAC addresses. MAC addresses and limit the number of users that can access the device.ДЄging time for dynamically learned MAC addresses This function helps prevent attacks using forged Of MAC addresses that a device can learn and the rate at which a device The MACДЄddress learning limit function allows you to set the maximum number As a result, theДevice cannot learn MAC address entries of authorized users. Table, which causes a MAC address table overflow. The forged MAC address entries and adds the entries to the MAC address To attack user devices or networks through a device, the device learns A device discards packets destined for static blackhole MAC

Using forged MAC addresses, configure MAC addresses of untrusted usersДЄs blackhole MAC addresses. Table space and prevent hackers from attacking a device or network MAC address entries will not be lost even if the device is reset,ДЄn interface board on the device is hot swapped, or the interfaceД®ntries (unauthorized users, for example) from using the MAC address MAC address entries are used to discard frames with specified destination Or the server, a static MAC address can be configured and added toД®ntries: configured manually and delivered to interface boards. On a network with unchanged users or a device isД¬onnected to an important server, to prevent hacker attacks on devices The configured static MAC addressД®ntries will not be lost even if the device is reset, an interfaceД«oard on the device is hot swapped, or the interface board is reset. Static entries: configured manually and delivered to interfaceД«oards. The device must be enabled to learn source MAC addresses. Resets, dynamic MAC address entries are lost.ДЄutomatically learns source MAC addresses and adds them to a MAC address Resets, an interface board is hot swapped, or the interface board DynamicД®ntries age after a specified period of time elapses. Manually configured MAC addressД®ntries take precedence over dynamically generated entries.Дynamic entries: learned and stored by interface boards. The MACДЄddresses of user devices are bound to access interfaces to prevent To improve interface security, a network administrator can manuallyДЄdd specified MAC address entries to the MAC address table. Should be forwarded to authorized users are forwarded to hackers. If hackers set the source MAC addresses of attack packets to the MACДЄddresses of authorized users and access a device through interfacesДifferent from the interfaces that authorized users access, the device Sent by authorized users or hackers, which poses security threats. If the entry is updated before its life cycle expires, the aging timeДЄutomatically learns all source MAC addresses carried in packets toД«uild a MAC address table, it does not check whether the packets are The entriesДЄutomatically generated in a MAC address table are not always valid.Д®ach entry has a life cycle. The MAC address table needs to be updated constantly. Learns source MAC addresses, generates MAC address entries, and adds Bridge domain-based MAC address learning helps devices isolateД«roadcast domains in a VSI and prevents the learned MAC address entriesДЄutomatically generated MAC address entries Traffic in various bridge domains are distinguished using bridge domain Virtual private LAN service (VPLS) networks, multiple bridge domainsД¬an transmit traffic of the same virtual switch instance (VSI), and Address table, also called a MAC table, which is used to forward traffic.Д®VC devices learn MAC addresses based on bridge domains.
