IEEE 802.1ag supports fault detection through Continuity Check Messages (CCM). CCM is 
somewhat like the “keep-alive” message. By default, every 802.1ag-capable network device 
(ND) 

sends out “heart-beat” style CCM periodically. Hence, by configuring a list of expected 

existent remote 802.1ag-capable NDs, the local 802.1ag-capable ND can detect the health 
status of its connection to the remote ND. 
 

Fault verification 

IEEE 802.1ag supports fault verification through Loopback Messages (LBM) and Loopback 
Reply (LBR). The LBM/LBR mechanism is similar to ICMP “ping” function in the IP network. 
However, since the interfaces of an ND in an Ethernet network may not possess their 
individual IP address, the operator can not achieve fault verification by ICMP “ping” in such 
a network environment. 

 
Fault isolation 

In addition to the LBM/LBR mechanism, IEEE 802.1ag supports fault isolation

 

through 

Linktrace Messages (LTM) and Linktrace Reply (LTR). The LTM/LTR mechanism is similar to 
the 

“trace route” function in the IP network. However, since the interfaces of an ND in an 

Ethernet network may not possess their individual IP address, the operator can not achieve 
fault isolation by “trace route” in such a network environment. 
 
IEEE 802.1ag also defines the following network error status to be conveyed in the CCM. 
 

MACstatus

  

Either some remote ND is reporting its interface as not ready to pass both the data packets 
and BPDU, or all remote NDs are reporting their interfaces as not able to pass ordinary data 
packets. 

RemoteCCM

  

The ND is not receiving valid CCMs from at least one of the remote NDs. 

ErrorCCM

  

The ND has received at least one invalid CCM whose CCM Interval has not yet timed out. 

XconCCM

  

The ND has received at least one CCM from either another VLAN or a lower MD Level 
whose CCM Interval has not yet timed out.
