Monitoring the status of devices in a VPLS network in a Provider’s Maintenance Domain
6
Verifying connectivity in a VPLS network using
IEEE 802.1ag Loopback
You can manually monitor the status of VPLS peers using IEEE 802.1ag CFM Linktrace (MAC
traceroute) and CFM Loopback (MAC Ping) as shown below.
Syntax: [no] cfm linktrace domain name ma ma-name src- mep mep-id target-mip
HH:HH:HH:HH:HH:HH | target-mep mep-id} [timeout timeout] [ttl TTL]
The domain name parameter specifies the maintenance domain to be used for a linktrace
message. The name attribute is case-sensitive.
The ma ma-name parameter specifies the maintenance association to be used for a linktrace
message. The name attribute is case-sensitive.
The src-mep mep-id parameter specifies the Source ID in the range 1-8191.
The target-mip HH:HH:HH:HH:HH:HH parameter specifies the MAC-address of the MIP linktrace
destination.
The target-mep mepid parameter specifies the ID of the linktrace destination.
The timeout timeout parameter specifies the timeout used to wait for linktrace reply. The default
value is 1-30 seconds.
The ttl TTL parameter specifies the initial TTL field value in the range 1-64.The default is 8 seconds.
CCM Count
Displays the total number of Continuity Check messages (CCMs) that are sent.
RDI
Remote Defect Indicator
Port Status
The status of a port
Intf Status
The status of the interface
Intvl Error
Displays Y if there has been an interval error and N if no interval errors have been
detected.
Seq Error
Displays Y if there has been a sequence error and N if no sequence errors have been
detected.
