CFM Commands
• One-way frame delay measurement requires the clocks at the transmitting and receiving MEPs
to be synchronized. For the purposes of frame delay variation measurement, which is based on
the difference between subsequent frame delay measurements, the requirement for clock
synchronizations can be relaxed since the out-of-phase period can be eliminated in the
difference of subsequent frame delay measurements.
Example
This example sends one-way delay-measure requests to a remote MEP.
Console#ethernet cfm delay-measure one-way src-mep 1 dest-mep 2 md voip ma rd
Console#
ethernet cfm delay-measure two-way
This command sends on-demand two-way delay-measure requests to a specified MEP, which
subsequently returns a time-stamped delay-measure reply.
Syntax
ethernet cfm delay-measure two-way [src-mep source-mpid] {dest-mep destination-mpid |
mac-address} md domain-name ma ma-name [count transmit-count] [interval interval]
[size packet-size] [timeout timeout]
source-mpid – The identifier of a source MEP that will send delay-measure messages.
(Range: 1-8191)
destination-mpid – The identifier of a remote MEP that is the target of the delay-measure
messages. (Range: 1-8191)
mac-address – MAC address of a remote MEP that is the target of the delay-measure
messages. This must be the unicast address. A multicast MAC address cannot be used.
This address can be entered in either of the following formats: xx-xx-xx-xx-xx-xx or
xxxxxxxxxxxx
domain-name – Domain name. (Range: 1-43 alphanumeric characters)
ma-name – Maintenance association name. (Range: 1-43 alphanumeric characters,
maximum length is 44 minus the length of the domain name)
count – The number of times to send a delay-measure message. (Range: 1-5)
interval – The interval between the transmission of delay-measure messages.
(Range: 1-5 seconds)
packet-size – The size of the delay-measure message. (Range: 64-1518 bytes)
timeout - The timeout to wait for a response. (Range: 1-5 seconds)
Default Setting
Count: 5
Interval: 1 second
Packet Size: 64 bytes
Timeout: 5 seconds
Command Mode
Privileged Exec
