Syntax

Release Information

Command introduced in Junos OS Release 9.5.

Command introduced in Junos OS Release 11.4 for EX Series switches.

Description

On MX Series routers with Ethernet interfaces on Dense Port Concentrators (DPCs), display ETH-DM delay statistics.

On EX Series switches, display delay measurement results.

Options

count entry-count(Optional) Number of entries to display from the statistics table. The range of values is 1 through 100. The default value is 100 entries.
local-mep mep-id(Optional) Numeric identifier of the local MEP. On MX Series routers, the range of values is 1 through 8192. On EX Series switches, the range of values is 1 through 8191.
maintenance-association ma-nameName of an existing CFM maintenance association.
maintenance-domain md-nameName of an existing connectivity fault management (CFM) maintenance domain.
remote-mep remote-mep-id(Optional) Numeric identifier of the remote MEP. On MX Series routers, the range of values is 1 through 8192. On EX Series switches, the range of values is 1 through 8191.

Table 1: show oam ethernet connectivity-fault-management delay-statistics and mep-statistics Output Fields

Output Field Name

Field Description

MEP identifier

Maintenance association end point (MEP) numeric identifier.

MAC address

Unicast MAC address configured for the MEP.

Remote MEP count

Number of remote MEPs (unless you specify the remote-mep option).

Remote MEP identifier

Numeric identifier of the remote MEP.

Remote MAC address

Unicast MAC address of the remote MEP.

Index

Index number that corresponds to the ETH-DM entry in the CFM database.

One-way delay (usec)

For a one-way ETH-DM session, the frame delay time, in microseconds, measured at the receiver MEP.

For a detailed description of one-way Ethernet frame delay measurement, see the ITU-T Y.1731 Ethernet Service OAM topics in the Junos OS Network Interfaces Library for Routing Devices.

Two-way delay (usec)

For a two-way ETH-DM session, the frame delay time, in microseconds, measured at the initiator MEP.

For a detailed description of two-way Ethernet frame delay measurement, see the ITU-T Y.1731 Ethernet Service OAM topics in the Junos OS Network Interfaces Library for Routing Devices.

Average one-way delay

Best-case one-way delay

Lowest one-way frame delay for the statistics displayed.

Worst-case one-way delay
