Description Platforms Supported: 7210 SAS-X, 7210 SAS-R6 and 7210 SAS-R12.
To support 100ms CCM timers in hardware for G.8032 MEPs, user needs to reserve a VLAN tag value for
exclusive use by G.8032 MEPs configured for a particular ring port (for the MEP configured under the path
command). This command allows the user to tell the system which VLAN tag is reserved for use with this
G.8032 MEP. This value can be the same one as configured with raps-tag value. Use of this command turns
on use of 100ms CCM timers for this MEP. The system checks that the configured value is not in use by any
SAP (as a SAP tag) configured on the port and not in use as a control-sap-tag by any other G.8032 instance
on that port. Maximum of four hardware based control MEPs can be configured on a port.
The VLAN should be reserved for all port encapsulation type. In other words, NULL encapsulated port,
Dot1q encapsulated port, and QinQ encapsulated ports that need to use G.8032 MEPs with 100ms CCM
timers need to reserve a VLAN for use. Every G.8032 instance configured for the port, needs a VLAN value
reserved for its use. Each G.8032 ring instance must use a different VLAN value, not in use currently by any
other G.8032 instance on the same port.
Notes:
• User needs to ensure that the VLAN value specified as control-sap-tag must not be received as the out-
ermost VLAN tag on any of the SAPs in use on the same port. For example, if control-sap-tag is config-
ured as 550, then any SAP (NULL, dot1q, dot1q Default SAP, Q1.Q2 SAP, Q1.* SAP) configured on
the port cannot receive any CFM packet that matches the VLAN tag 550.
• Configuration of control-sap-tag is interoperable with other devices. This is an internal tag used for pro-
cessing CCMs in the fastpath. This tag is not sent on the wire.
The no form of the command reverts the ring port to use the raps-tag configured for the path and use of
1second CCM timers.
Parameters tag-range — Specifies the tag range.
Values
eth-test-enable
Syntax [no] eth-test-enable
Context config>eth-ring>path>eth-cfm>mep
Description This command enables eth-test functionality on MEP. For this test to work, operators need to configure
ETH-test parameters on both sender and receiver nodes. The ETH-test then can be done using the following
OAM commands:
