ping ethernet
Syntax
Release Information
Command introduced in Junos OS 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.
