Release Information

Command introduced in Junos OS Release 13.2 for MX Series routers.

Description

On MX Series routers with Modular Port Concentrators (MPCs) with Ethernet interfaces, display the on-demand ETH-SLM statistics.

Options

count entry-count
—

(Optional) Number of entries to display from the statistics table. The range of values is from 1 through 100. The default value is 100.

local-mep local-mep-id
—

(Optional) Numeric identifier of the local MEP. The range of values is from 1 through 8192.

maintenance-association ma-name
—

Name of an existing CFM maintenance association.

maintenance-domain md-name
—

Name of an existing connectivity fault management (CFM) maintenance domain.

remote-mep remote-mep-id
—

(Optional) Numeric identifier of the remote MEP. The range of values is from 1 through 8192.

Table 1: show oam ethernet connectivity-fault-management synthetic-loss-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.

SLM packets sent

Total number of synthetic loss message (SLM) PDU frames sent from the source MEP to the remote MEP during this ETH-SLM session.

SLM packets received

Total number of synthetic loss message (SLM) PDU frames that the remote MEP received from the source MEP during this ETH-SLM session.

SLR packets sent

Total number of synthetic loss reply (SLR) PDU frames that the remote MEP sent to the source MEP during this measurement session.

SLR packets received

Total number of synthetic loss reply (SLR) PDU frames that the source MEP received from the remote MEP during this measurement session.

Local TXFC1 value

Number of synthetic frames transmitted to the peer MEP for a test ID. A test ID is used to distinguish each synthetic loss measurement because multiple measurements can be simultaneously activated also on a given CoS and MEP pair. It must be unique at least within the context of any SLM for the MEG and initiating MEP.

Local RXFC1 value

Number of synthetic frames received from the peer MEP for a test ID. The MEP generates a unique Test ID for the session, adds the source MEP ID, and initializes the local counters for the session before SLM initiation. For each SLM PDU transmitted for the session (test ID), the local counter TxFC1 is sent in the packet.

Last Received SLR frame TXFCf(tc)

Value of the local counter TxFCl at the time of SLM frame transmission.

Last Received SLR frame TXFCb(t

Value of the local counter RxFCl at the time of SLR frame transmission.

Frame loss (near-end)

Count of frame loss associated with ingress data frames.

Frame loss (far-end)

Count of frame loss associated with egress data frames.
