• If the acceptance of this address would increase the secure address count on the service instance beyond the maximum number allowed, an attempt is made to make room by removing an existing address from Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 102: Mac Address Deny List
Before an unknown MAC address is learned, a series of checks are run against a set of configured and operational constraints. If any of these checks fails, the address is not learned, and a configured violation response is triggered. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 103: Static And Dynamic Mac Addresses
However, there are no restrictions on the count that is configured on the service instance. The table below shows an example of an initial configuration where three service instances are configured on a bridge domain: Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)

Type 1 Violation --The address of the ingress frame cannot be dynamically learned due to a deny list, or because doing so would cause the maximum number of secure addresses to be exceeded (see the MAC Address Limiting and Learning, on page 84). Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 105: Mac Address Aging Configuration
That is, the age of the MAC address is measured from the instant that it was first encountered on the service instance. This interpretation can be modified by using the mac security aging time aging-time Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 106: Sticky Mac Address Configurations
When MAC security is enabled on a service instance, all existing MAC table entries for the service instance are purged. Then, permitted MAC address entries and sticky addresses are added to the MAC table, subject to the prevailing MAC address limiting constraints on the bridge domain. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 107: Mac Security Disabled On A Service Instance
The MAC table is scanned for addresses that are attributable to this service instance, and dynamically learned MAC addresses are removed when the new MAC address limit is less than the old MAC address limit. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)

Ethernet island, and is identified by a globally unique service ID. A customer service instance can be point-to-point or multipoint-to-multipoint. The figure below shows two customer service instances. Service Instance Green is point to point; Service Instance Blue is multipoint to multipoint. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 144: Maintenance Domain
A unique maintenance level in the range of 0 to 7 is assigned to each domain by a network administrator. Levels and domain names are useful for defining the hierarchical relationship that exists among domains. The hierarchical relationship of domains parallels the structure of customer, service provider, and operator. The Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 145: Maintenance Associations And Maintenance Points
Maintenance Associations and Maintenance Points A maintenance association (MA) identifies a service that can be uniquely identified within the maintenance domain. The CFM protocol runs within a maintenance association. A maintenance point is a demarcation Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 146: Carrier Ethernet Configuration Guide (Cisco Asr 920 Series
If port on which the MEP is configured is blocked by Spanning-Tree Protocol (STP), the MIP can receive and might respond to CFM messages from both the wire and relay side, but cannot forward any CFM messages. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 147: Maintenance Point
Maintenance points on device ports act as filters that confine CFM frames within the bounds of a domain by dropping frames that do not belong to the correct level. Maintenance points must be explicitly configured on Cisco devices. Two classes of maintenance points exist, MEPs and MIPs. Maintenance Endpoints Maintenance endpoints (MEPs) have the following characteristics: •...
Page 148: Maintenance Intermediate Points
A MIP has only one level associated with it and the command-line interface (CLI) does not allow you to configure a MIP for a domain that does not exist. The figure below illustrates MEPs and MIPs at the operator, service provider, and customer levels. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 149: Cfm Messages
• Catalogued by MIPs at the same maintenance level. • Terminated by remote MEPs at the same maintenance level. • Unidirectional and do not solicit a response. • Carry the status of the port on which the MEP is configured. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 150: Cross-Check Function
SNMP Traps The support provided by the Cisco software implementation of CFM traps is Cisco proprietary information. MEPs generate two types of Simple Network Management Protocol (SNMP) traps, continuity check (CC) traps and cross-check traps.
Page 151: Ethernet Cfm And Ethernet Oam Interaction
The distinction between a VLAN port and the EFP is the encapsulation. VLAN ports use a default dot1q encapsulation. For EFPs, untagged, single tagged, and double tagged encapsulation exists with dot1q and IEEE dot1ad EtherTypes. Different EFPs belonging to the same bridge domain can use different encapsulations. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)

• Determination of whether the domain should be inward or outward. SUMMARY STEPS 1. Determine operator level MIPs. 2. Determine operator level MEPs. 3. Determine service provider MIPs. 4. Determine service provider MEPs. 5. Determine customer MIPs. 6. Determine customer MEPs. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 153: Carrier Ethernet Configuration Guide (Cisco Asr 920 Series
Determine customer MIPs. Customer MIPs are allowed only on the UNIs at the uPEs if the service provider allows the customer to run CFM. Otherwise, the service provider can configure Cisco devices to block CFM frames. • Configure a MIP on every uPE, at the UNI port, in the customer maintenance domain.

MAs within a domain. The MA direction is specified when the MA is configured. The short MA name must be configured on a domain before MEPs can be configured. The CFM protocol runs for a specific MA. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 267: Maintenance Domains
CFM at the operator level does not allow discovery of the network by the higher provider and customer levels. Network designers determine domain configurations. The following characteristics of domains are supported: • Name is a maximum of 63 characters in length. • Direction is specified when the MA is configured. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 268: Maintenance Points
At the request of an administrator, linktrace and loopback messages can also be transmitted. MEPs are either “Up” (toward the bridge) or “Down” (toward the wire). Support for Up MEPs varies by Cisco release. When the continuity-check static rmep command is configured on a port MEP and continuity checking does not detect a removed MEP, the port is set to MAC operation down and the interface protocol is set to down.
Page 269: Carrier Ethernet Configuration Guide (Cisco Asr 920 Series
An Ethernet CFM LBM can be generated on demand using the CLI. The source of a loopback message must be a MEP. Both Ethernet CFM LBMs and LBRs are unicast, and LBMs specify the destination MAC address or MEP identifier (MPID), VLAN, and maintenance domain. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 270: Cross-Check Function
SNMP Traps The support provided by the Cisco IOS XE software implementation of Ethernet CFM traps is Cisco proprietary information. MEPs generate two types of Simple Network Management Protocol (SNMP) traps, continuity check (CC) traps and cross-check traps.

Determine customer MIPs. Customer MIPs are allowed only on the UNIs at the uPEs if the service provider allows the customer to run CFM. Otherwise, the service provider can configure Cisco devices to block CFM frames. • Configure a MIP on every uPE, at the UNI port, in the customer maintenance domain.

This document describes how the IEEE 802.3ad Link Bundling feature leverages the EtherChannel infrastructure within Cisco IOS XE software to manage the bundling of Ethernet links. The supported Ethernet link types for link bundling are Gigabit Ethernet and Ten Gigabit Ethernet.
Page 368: Restrictions For Configuring Ieee 802.3Ad Link Bundling
Each EtherChannel has a numbered port-channel interface that must be manually created before interfaces can be added to the channel group. The configuration of a port-channel interface affects all LAN ports assigned to that port-channel interface. Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 369: Ieee 802.3Ad Link Bundling
IEEE 802.3ad Link Bundling provides a capability to dynamically provision, manage, and monitor various aggregated links and enables interoperability between various Cisco devices and devices of third-party vendors. LACP supports the automatic creation of EtherChannels by exchanging LACP packets between LAN ports.
Page 370: Benefits Of Ieee 802.3Ad Link Bundling
The following LACP enhancements are supported: • Four member links per LACP bundle. • Cisco nonstop forwarding (NSF), and nonstop routing (NSR) on Gigabit EtherChannel bundles. • Link failover time of 250 milliseconds or less and a maximum link failover time of 2 seconds; port channels remain in the LINK_UP state to eliminate reconvergence by the Spanning-Tree Protocol.

Supported Version 3 (L2TPv3), IPinIP, Any Transport Over Multiprotocol Label Switching (MPLS) (AToM) tunnels Layer 2 Tunneling Protocol Not Supported Version 2 (L2TPv2) MPLS (6PE) Supported Multicast VPN Not Supported VLANs Supported Carrier Ethernet Configuration Guide (Cisco ASR 920 Series)
Page 372: Guidelines For Lacp For Gigabit Interfaces Configuration
• Cisco Discovery Protocol enable is not supported on the port channel interface. • All LAN ports in a port channel should be enabled. If you shut down a LAN port in a port channel, the shutdown is treated as a link failure and the traffic is transferred to one of the remaining ports in the port channel.
