Triggering an Ethernet Frame Delay Measurements Session
Before Ethernet frame delay measurement statistics can be displayed, they must be
collected. To trigger Ethernet frame delay measurement, use the
monitor ethernet
delay-measurement (one-way | two-way) (remote-mac-address | mep identifier)
maintenance-domain name maintenance-association ma-id [count count] [wait time]
operational command.
The fields for this command are described in Table 3 on page 129 .
Table 3: Monitor Ethernet Delay Command Parameters
Description Parameter Range Parameter
Perform a one-way or two-way (round-trip) delay measurement. NA one-way or two-way
Send delay measurement frames to the destination unicast MAC address
(use the format xx:xx:xx:xx:xx:xx). Multicast MAC addresses are not
supported. Unicast MAC address remote-mac-address
The MEP identifier to use for the measurement. The discovered MAC
address for this MEP identifier is used. 1–8191 mep identifier
Specifies an existing maintenance domain (MD) to use for the
measurement. Existing MD name maintenance-domain
name
Specifies an existing maintenance association (MA) identifier to use for
the measurement. Existing MA identifier maintenance-association
ma-id
(Optional) Specifies the number of Ethernet frame delay frames to send.
The default is 10. 1–65535 (default: 10) count count
