Must not be a keyword keywords to avoid are all, default-action, map, help, and editbuffer. Must start with an alpha character and must be unique across all ACLs of all types. Maximum of 31 characters and may include a–z, A–Z, 0–9, the dash character (-), the underscore character (_), and the period character (.). When you enter the ACL name, follow these naming conventions: 
The following Ethertype protocol values were added to the valid protocol list: bpdu-sap, bpdu-snap, dtp, lacp, pagp, vtp. This command was integrated into Cisco IOS Release 12.2(33)SRA. Support for this command on the Supervisor Engine 2 was extended to Release 12.2(17d)SXB.
Add the ip keyword to the list of valid protocol names. Add the vlan vlan and cos value keywords and arguments. Support for this command was introduced on the Supervisor Engine 720. Global configuration (config) Command History Release Name of the ACL to which the entry belongs. No mac access-list extended name Syntax Description To remove MAC ACLs, use the no form of this command. To create an extended MAC access control list (ACL) and define its access control entries (ACEs), use the mac access-list extended command in global configuration mode.

Note The mac access-group command is supported on a VLAN subinterface only if a VLAN is already configured on the subinterface. #Cisco mac address table command 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.

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.

The basic CLI commands for all of them are the same, which simplifies Cisco device management. Almost all Cisco devices use Cisco IOS to operate and Cisco CLI to be managed.
