Bridge UP Interface

This article describes the configuration of the interface.

CLI Configurations

At Switch5

• Make interface P2 as up

your product(config)# interface gigabitethernet 0/2
your product(config-if)# no shutdown

SNMP Configurations

At Switch5

• Make interface P2 as up. [Index: Interface Number = 2]

% snmp0 set {{ifMainAdminStatus.2 up}}

Checking for CCM Errors

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

CLI Configurations

• Wait for 15 seconds and check if there is any link failure (error/fault/defect), after configuring interface P2 as up.

your product# show ethernet cfm errors
your product#

Shows no link failure, as no error is detected.

SNMP Configurations

• Wait for 15 seconds and check if there is any link failure (error/fault/defect), after configuring interface P2 as up.

Verifying and Isolating Fault

This section describes the initiation of the loopback and link trace messages to verify and isolate a fault.

CLI Configurations

At Switch1

• Initiate the LoopBack Transaction

your product# ping ethernet mac 00:05:02:03:04:02 domain OP7 vlan 2
Sending 1 Ethernet CFM loopback messages, timeout is 5 seconds

Success rate is 100.0 percent 1/1

• Initiate the LinkTrace Transaction

your product# traceroute ethernet mac 00:05:02:03:04:02 domain OP7 vlan 2
Traceroute to Macaddress 00:05:02:03:04:02    in domain  OP7 at level 7
with vlanId 2

SNMP Configurations

At Switch1

• Initiate the loopback transaction. [Index: ContextID = 0, MD-Index = 1, MA-Index = 1, MEP-ID = 1]

% snmp0 set {{fsMIEcfmMepTransmitLbmMessages.0.1.1.1 1}}
% snmp0 set {{fsMIEcfmMepTransmitLbmDestMacAddress.0.1.1.1 00:05:02:03:04:02}}
% snmp0 set {{fsMIEcfmMepTransmitLbmDestIsMepId.0.1.1.1 false}}
% snmp0 set {{fsMIEcfmMepTransmitLbmStatus.0.1.1.1 transmit}}

• Verify transmission of loopback messages between Switch1 and Switch6. [Index: ContextID = 0, MD-Index = 1, MA-Index = 1, MEP-ID = 1]

% snmp0 get {fsMIEcfmMepLbrIn.0.1.1.1}
{1.3.6.1.4.1.2076.160.1.0.7.1.20.0.1.1.1 Unsigned32 1}

{1.3.6.1.4.1.2076.160.1.0.7.1.30.0.1.1.1 INTEGER 0}

Shows no link failure between Switch 1 and Switch 6

• Initiate the linktrace transaction. [Index: ContextID = 0, MD-Index = 1, MA-Index = 1, MEP-ID = 1]

% snmp0 set {{fsMIEcfmMepTransmitLtmTargetIsMepId.0.1.1.1 false}}
% snmp0 set {{fsMIEcfmMepTransmitLtmTargetMacAddress.0.1.1.1 00:05:02:03:04:02}}
% snmp0 set {{fsMIEcfmMepTransmitLtmStatus.0.1.1.1 transmit}}

• Walk the Y1731 LTR table.

% snmp0 walk x fsMIY1731LtrTable { puts $x }
{1.3.6.1.4.1.29601.2.7.1.2.6.1.3.0.1.1.1.2.1 INTEGER 29}

{1.3.6.1.4.1.29601.2.7.1.2.6.1.3.0.1.1.1.2.3 INTEGER 109}

Shows no link failure between Switch1 and Switch5, as data of all three hops are present in the Ltrcache.
