Connectivity Fault Management (IEEE 802.1ag) NOTE: This feature is available on the Dell EMC NetworkingN1500/N2200 Switches Series switches only. The Connectivity Fault Management (CFM) feature, also known as Dot1ag, supports Service Level Operations, Administration, and Management (OAM). CFM is the OAM Protocol provision for end-to-end service layer instance in carrier networks. The CFM feature provides mechanisms to help perform connectivity checks, fault detection, fault verification and isolation, and fault notification per service in a network domain. For information about configuring IEEE 802.1ag settings, see "Connectivity Fault Management" on page 1013. Cisco Protocol Filtering The Cisco Protocol Filtering feature (also known as Link Local Protocol Filtering) filters Cisco protocols that should not normally be relayed by a bridge. The group addresses of these Cisco protocols do not fall within the IEEE defined range of the 802.1D MAC Bridge Filtered MAC Group Addresses (01-80-C2-00-00-00 to 01-80-C2-00-00-0F). For information about configuring LLPF, settings see "Port-Based Traffic Control" on page 939. DHCP Layer-2 Relay This feature permits Layer-3 relay agent functionality in Layer-2 switched networks. The switch supports Layer-2 DHCP relay configuration on individual ports, link aggregation groups (LAGs) and VLANs. For information about configuring Layer-2 DHCP relay settings see "Layer-2 and Layer-3 Relay Features" on page 1225. Switch Feature Overview 93
