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 routing platforms, 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.
