Cisco Systems Cisco IOS XR manual Verifying the Control Ethernet Connection

Chapter 3 Bringing Up the Cisco IOS XR Software on a Multishelf System

Integrated Switch System

SUMMARY STEPS

1.admin

2.clear controller switch errdisable {port {FE GE} {0 1}} {location node-id}}

3.clear controller switch inter-rack {errdisable {ports {number all} statistics {all ports number}} {location node-id}

DETAILED STEPS

	Command or Action	Purpose
Step 1	admin	Places the router in administration EXEC mode.
	Example:
	RP/0/RP0/CPU0:router# admin
Step 2	clear controller switch errdisable {port {FE GE}	Clears the err-disable state of the switch port for the
	{0 1}} {location node-id}}	RP ports.
	Example:	• Use the FE keyword to display the ports for Fast
		Ethernet (FE).
	RP/0/RP0/CPU0:router(admin)# clear controller switch
	errdisable port GE 1 location f0/sc0/cpu0	• Use the GE keyword to display the ports for
		Gigabit Ethernet (GE).
Step 3	clear controller switch inter-rack {errdisable	Clears the err-disable state of the inter-rack switch
	{ports {number all} statistics {all ports	ports on the 22-port SCGE.
	number}} {location node-id}
	Example:
	RP/0/RP0/CPU0:router(admin)# clear controller switch
	inter-rack statistics all location f0/sc0/cpu0

Verifying the Connections of the Integrated Switch Control Network

This section presents how to verify the connections and operations of the integrated switch control network with 22-port SCGEs:

•Verifying the Control Ethernet Connection, page 3-25

•Verifying the Port Statistics, page 3-26

•Verifying Bidirectionality, page 3-27

•Verifying Unidirectional Link Detection (UDLD) Protocol Information, page 3-27

•Verifying Spanning Tree Protocol Information, page 3-27

Verifying the Control Ethernet Connection

To verify the control Ethernet connection on intra-rack switches, use the show controllers switch command with the ports and location keywords, as shown in the following example:

RP/0/RP0/CPU0:router(admin)# show controllers switch 0 ports location 0/rp0/Cpu0

FE Port	0 : Up, STP State : FORWARDING (Connects to - F0/SC0)
FE Port	1 : Up, STP State : FORWARDING (Connects to - F0/SC1)
