    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 1.

    Table 1: Monitor Ethernet Delay Command Parameters

    Parameter

    Parameter Range

    Description

    one-way or two-way

    NA

    Perform a one-way or two-way (round-trip) delay measurement.

    remote-mac-address

    Unicast MAC address

    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.

    mep identifier

    1–8191

    The MEP identifier to use for the measurement. The discovered MAC address for this MEP identifier is used.

    maintenance-domain name

    Existing MD name

    Specifies an existing maintenance domain (MD) to use for the measurement.

    maintenance-association ma-id

    Existing MA identifier

    Specifies an existing maintenance association (MA) identifier to use for the measurement.

    count count

    1–65535 (default: 10)

    (Optional) Specifies the number of Ethernet frame delay frames to send. The default is 10.

    wait time

    1–255 seconds (default: 1)

    (Optional) Specifies the number of seconds to wait between frames. The default is 1 second.

    If you attempt to monitor delays to a nonexistent MAC address, you must exit the application manually using ^C:

    user@host> monitor ethernet delay-measurement two-way 00:11:22:33:44:55
    Two-way ETH-DM request to 00:11:22:33:44:55, Interface ge-5/2/9.0
^C
