Ethernet Test Signal (ETH-TEST)
When ETH-TEST function is enabled, it performs diagnostics tests to verify
bandwidth throughput, frame loss, bit errors, etc.
Y.1731 Functions for Performance Monitoring
ITU-T Y.1731 OAM supports the following functions for performance monitoring:
•
Frame Loss Measurement (ETH-LM)
Using the frame with ETH-LM information, the switch collects counter values
applicable for ingress and egress service frames where the counters maintain a
count of transmitted and received data frames between a pair of MEPs.
•
Frame Delay Measurement (ETH-DM)
Frame delay and frame delay variation measurements are performed by exchanging
frames with ETH-DM information between MEPs.
7.7.1
Enabling Y.1731 OAM
To enable/disable ITU-T Y.1731 OAM function globally, use the following command.
Command
Mode
Description
ethernet oam enable
Global
Enables ITU-T Y.1731 OAM function.
ethernet oam disable
Disables ITU-T Y.1731 OAM function.
7.7.2
Creating Y.1731 Entity
ITU-T Y.1731 uses the entities that are managed and the management functional compo-
nents. An ME is an entity that requires management. A MEG includes a set of MEs that
satisfy the some conditions. To implement Y.1731 OAM, you should create MEG and
specify its level.
7.7.2.1
Creating MEG
To create a MEG name and specify its option, use the following command.
Command
Mode
Description
ethernet oam meg MEG-NAME
level
<0-7> [
primary-vlan

Global
Creates a MEG name and specifies MEG
’s level.
MEG-
NAME: MEG’s name, ICC (6 bytes) + UMC (6
bytes)
0-7: MEG
’s level to use (default: 0)
VLAN: MEG
’ vlan ID
ethernet oam meg MEG-NAME

MEG-
NAME
Creates a MEG name and propagates LOC to some
MEG.
