Configuring Bridge UP Interface

This article describes the configuration of the interface.

CLI Configurations

At CUST3

• Make interface P2 of CUST3 as up.
  your product(config)# interface gigabitethernet 0/2
  your product(config-if)# no shutdown

• Wait for 5 seconds and check error/fault/defect.

SNMP Configurations

At CUST3

• Set interface P2 of CUST3 as up. [Index: Interface Number = 2]
  % snmp0 set {{ifMainAdminStatus.2 up }}

• Wait for 5 seconds and check error/fault/defect.

Checking for CCM Errors

This section describes the checking of CCM errors after configuring the interface as up.

CLI Configurations

At CUST1

• Wait for 5 seconds after configuring the interface as up and then check for error/fault/defect
  your product# show ethernet cfm errors

MEP-ID :  10
Level VLAN RMEP-ID   Current defect type
----- ---- -------   -------------------
5     2    30        mac status defect

Implies that CUST-3 is sending CCM with port-status as blocked.
At CUST3

• Wait for 5 seconds after configuring the interface as up and then check for error/fault/defect
  your product# show ethernet cfm errors

MEP-ID :  30
Level VLAN RMEP-ID   Current defect type
----- ---- -------   -------------------
5     2    10        remote defect indication

Implies that CUST-1 is sending CCM with RDI as enabled.

SNMP Configurations

At CUST1

• Wait for 5 seconds after configuring the interface as up and then check for error/fault/defect. [Index: ContextID = 0, MD-Index = 1, MA-Index = 1, MEP-ID = 10]
  % snmp0 get {fsMIEcfmMepDefects.0.1.1.10 }

{1.3.6.1.4.1.2076.160.1.0.7.1.14.0.1.1.10 {OCTET STRING} 40}

Implies that CUST-3 is sending CCM with port-status as blocked.

At CUST3

• Wait for 5 seconds after configuring the interface as up and then check for error/fault/defect. [Index: ContextID = 0, MD-Index = 1, MA-Index = 1, MEP-ID = 30]

% snmp0 get {fsMIEcfmMepDefects.0.1.1.30 }

{1.3.6.1.4.1.2076.160.1.0.7.1.14.0.1.1.30 {OCTET STRING} 80}

Implies that CUST-1 is sending CCM with RDI as enabled.

Verifying and Isolating Fault

This section describes the initiation of the loop back and link trace messages to verify and isolate fault.

CLI Configurations

At CUST1

• Initiate the Loopback transaction from MEP at CUST1 to MEP at CUST3.
  your product# ping ethernet mac 00:03:02:03:04:02 domain OP1 vlan 2

Sending 1 Ethernet CFM loopback messages, timeout is 5 seconds
Success rate is 100.0 percent 1/1

• Initiate Traceroute from MEP at CUST1 to MEP at CUST3
  your product# traceroute ethernet mac 00:03:02:03:04:02 domain OP1 vlan 2

Traceroute to Macaddress 00:03:02:03:04:02    in domain  OP1 at level 5
with vlanId 2

SNMP Configurations

At CUST1

• Initiate the loopback transaction from MEP at CUST1 to MEP at CUST3. [Index: ContextID = 0, MD-Index = 1, MA-Index = 1, MEP-ID = 10]
  % snmp0 set {{fsMIEcfmMepTransmitLbmMessages.0.1.1.10 5 }}

  % snmp0 set {{fsMIEcfmMepTransmitLbmDestIsMepId.0.1.1.10 false }}
  % snmp0 set {{fsMIEcfmMepTransmitLbmStatus.0.1.1.10 transmit }}

• Check whether the LBRs are not received.
  % snmp0 get {fsMIEcfmMepLbrIn.0.1.1.10 }

{1.3.6.1.4.1.2076.160.1.0.7.1.20.0.1.1.10 Unsigned32 10}

• Initiate traceroute from MEP at CUST1 to MEP at CUST3. [Index: ContextID = 0, MD-Index = 1, MA-Index = 1, MEP-ID = 10]
  % snmp0 set {{fsMIEcfmMepTransmitLtmTargetIsMepId.0.1.1.10 false }}

  % snmp0 set {{fsMIEcfmMepTransmitLtmStatus.0.1.1.10 transmit }}

• Check whether LTM is transmitted successfully
  % snmp0 walk x fsMIEcfmLtrTable { puts $x }
