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:
