Cisco Systems A9014CFD Verifying IMA Configurations, L2transport encapsulation for the VCC mode

Chapter 36 Configuring Inverse Muliplexing over ATM

Configuring ATM IMA over MPLS

DETAILED STEPS

	Command	Purpose
Step 1	enable	Enables privileged EXEC mode.
		• Enter your password if prompted.
	Example:
	Router> enable
Step 2	configure terminal	Enters the global configuration mode.
	Example:
	Router# configure terminal
Step 3	interface ATMslot/IMAgroup-number	Specifies the slot location and port of IMA interface group.
		• slot—Specifies the slot location of the ATM IMA port adapter.
	Example:	• group-number—Specifies the group number of the IMA group.
	Router(config)# interface ATM0/IMA0
Step 4	VPI/VCI l2transport	Specifies the VPI and VCI and configures them in layer 2 transport
		mode.
	Example:
	Router(config-if)# 100/12 l2transport
Step 5	encapsulation encapsulation-type	Sets the encapsulation type to AAL5. AAL5 is the default
		l2transport encapsulation for the VCC mode.
	Example:
	Router(config-if-atm-l2trans-)#
	encapsulation aal5
Step 6	xconnect ip-address port-number	Binds an attachment circuit to the ATM IMA interface to create a
	encapsulation mpls	pseudowire.
	Example:
	Router(config-if-atm-l2trans-)#
	xconnect 25.25.25.25 125 encapsulation
	mpls

Verifying IMA Configurations

	To verify the IMA configurations, use the show ima interface command.
	Router# show ima interface ATM0/IMA3
	ATM0/IMA3 is up, ACTIVATION COMPLETE
	Slot 0 Slot Unit 0 unit 3, CTRL VC -1, Vir -1, VC -1
	IMA Configured BW 3022, Active BW 3022
	IMA version 1.0, Frame length 64
	Link Test: Disabled
	Auto-Restart: Disabled
	ImaGroupState: NearEnd = operational, FarEnd = operational
	ImaGroupFailureStatus = noFailure
	IMA Group Current Configuration:
	ImaGroupMinNumTxLinks = 1 ImaGroupMinNumRxLinks = 1
	ImaGroupDiffDelayMax = 200 ImaGroupNeTxClkMode = independent(itc)
	ImaGroupFrameLength = 64 ImaTestProcStatus = disabled
