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