ping ethernet

Syntax

ping ethernet mac-address maintenance-domain md-name maintenance-association ma-name <count count><size bytes><wait seconds>

Release Information

Command introduced in JUNOS Release 9.1.

Description

On M320, MX Series, T320, and T640 routers, check the reachability of a remote IEEE 802.1ag OAM maintenance association end point (MEP) or maintenance association intermediate point (MIP). Type Ctrl+c to interrupt a ping ethernet command.

Options

mac-address: Send loopback protocol messages to the MEP with the specified Ethernet MAC address.
maintenance-association ma-name: Send loopback protocol messages to the MEP for the specified maintenance association.
maintenance-domain md-name: Send loopback protocol messages to the MEP for the specified maintenance domain.
count count: (Optional) Number of ping requests to send. The range of values is from 1 through 65,535. If the count is not specified 4 loopback messages are sent. Terminate the ping command by typing Ctrl+c.
size bytes: (Optional) The length, in bytes, of the data type, length, and value (TLV) sent in the loopback message. The range of values is from 1 through 1400. The default is 64 bytes.
wait seconds: (Optional) The amount of time, in seconds, to wait to send the next loopback message. The range of values is from 1 through 255. The default wait time is 1 second.
