o
MAC Address (default) – If you select MAC Address, you must enter the MAC address of the interface to
which you want to send the loopback in the Loopback Messages Destination MAC Address. If you are not
sure what the interface's MAC address is, you can get it from the Interface Manager by selecting Platform
> Management > Interface Manager.
4 In the Loopback messages to be transmitted field, select the number of loopback messages to transmit (0 –
1024). If you select 0, loopback will not be performed.
5 In the Loopback Messages Interval field, select the interval (in seconds) between each loopback message
(0.1 – 60). You can select in increments of 1/10 second. However, the lowest possible interval is 1 second. If
you select a smaller interval, the actual interval will still be 1 second.
6 In the Loopback Messages Frame Size field, select the frame size for the loopback messages (64 – 1516).
Note that for tagged frames, the frame size will be slightly larger than the selected frame size.
7 In the Loopback Messages Priority field, select a value (0 – 7) for the priority bit for tagged frames.
8 In the Drop Enable field, choose the value of the DEI field for tagged loopback frames (True or False). The
default value is False.
9 In the Loopback Messages Data Pattern Type field, select the type of data pattern to be sent in an OAM
PDU Data TLV. Options are All Zeros and All Ones. The default value is All Zeros.
10 Click Apply to begin the loopback. The Loopback session state field displays the status of the loopback:
o
SOAM Loopback Complete – The loopback has been successfully completed.
o
SOAM Loopback Stopped – The loopback has been manually stopped.
o
SOAM Loopback Failed – The loopback failed.
o
SOAM Loopback Active – The loopback is currently active.
o
SOAM Loopback Inactive – No loopback has been initiated.
The remote interface will answer and the loopback session will be completed if either of the following is true:
•
A remote MEP has been defined on the destination interface.
•
A MIP has been defined on the destination interface. See
Note
To manually stop a loopback, you must use the CLI. Enter the following command in root view:
root> ethernet soam loopback stop meg-id <meg-id> mep-id <mep-id>.
