ping ethernet

Syntax

ping ethernet mac-address maintenance-domain md-name maintenance-association ma-name <count count><host mac-address-of-remote-host><logical-system logical-system-name><mep identifier><size bytes><wait seconds>

Release Information

Command introduced in Junos OS Release 9.1.

Support for multicast MAC addresses introduced in Junos OS Release 12.3R2.

Description

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.

host-mac-address

(Optional) Unicast or multicast MAC address of the remote host in xx:xx:xx:xx:xx:xx format. For example, this can be a multicast MAC address in the 01:80:c2:00:00:3x format (where x = 0 through 7).

logical-system logical-system-name

(Optional) Run the command for the specified logical system.

mep identifier

(Optional) MEP identifier of the remote host. The default MEP identifier is 1. The range is 1 through 8191.

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) Maximum wait time, in seconds, to send the next loopback message. The range of values is from 1 through 255. The default wait time is 1 second.

Table 1: ping ethernet Output Fields

Field Name

Field Description

PING to

The MAC address of the remote MEP or MIP to which the request message packets are being sent.

Interface

The local Ethernet interface from which the request message packets are being sent.

ping responses

For each loopback message response received, display the number of TLV bytes, the MAC address of the remote MEP or MIP, and the sequence number.

ping statistics

Display totals for the following:

  • Request packets transmitted
  • Response packets received
  • Expected response packets not received
