Cisco mac address tablehistory series#
On Catalyst 6500 series switches, this command is supported on Layer 2 ports only. If the specified MAC ACL does not exist on the interface or subinterface, all packets are passed.
Cisco mac address tablehistory software#
If the access list denies the address, the software discards the packet and returns an Internet Control Message Protocol (ICMP) host unreachable message. If the MAC access list permits the address, the software continues to process the packet. After a networking device receives a packet, the Cisco IOS software checks the source MAC address of the Gigabit Ethernet, 802.1Q VLAN, or 802.1Q-in-Q packet against the access list. MAC ACLs are applied on incoming traffic on Gigabit Ethernet interfaces and VLAN subinterfaces. This command was integrated into Cisco IOS Release 12.2(33)SXH. This command was introduced on the Cisco 12000 series Internet router. Subinterface configuration (config-subif) Command History Release No access list is applied to the interface or subinterface. This is a decimal number from 700 to 799. Number of a MAC ACL to apply to an interface or subinterface (as specified by a access-list (MAC) command). No mac access-group access-list-number in Syntax Description To remove a MAC ACL, use the no form of this command. To use a MAC access control list (ACL) to control the reception of incoming traffic on a Gigabit Ethernet interface, an 802.1Q VLAN subinterface, an 802.1Q-in-Q stacked VLAN subinterface, use the mac access-group command in interface or subinterface configuration mode.

For example, your service provider might perform access control based on the MAC address. You might want to assign unique MAC addresses to subinterfaces. Subinterfaces - All subinterfaces of a physical interface use the same burned-in MAC address. Physical interfaces - The physical interface uses the burned-in MAC address. Default MAC Addressesĭefault MAC address assignments depend on the type of interface. If the active unit fails over and the standby unit becomes active, the new active unit starts using the active MAC addresses to minimize network disruption.Īctive and standby MAC addresses are configured on the Advanced tab when configuring an interface. You can manually configure Media Access Control (MAC) addresses to override the default value.įor a high availability configuration, you can configure both the active and standby MAC address for an interface.
