Step 5 Use the show atm vc interface command to confirm the connections are up and the configuration is
valid.
Switch# show atm vc interface atm 10/0/0.3
Interface VPI VCI Type X-Interface X-VPI X-VCI Encap Status
ATM10/0/0 0 35 PVC ATM0 0 271 LSCNTL UP
ATM10/0/0 0 36 PVC ATM0 0 272 LSDATA UP

ATM10/0/0 0 323 PVC Gi3/0/1 0 68 LSDATA UP
ATM10/0/0 0 325 PVC Gi3/0/1 0 70 LSDATA UP
ATM10/0/0 0 326 PVC Gi3/0/1 0 71 LSDATA UP
Step 6 Check the Status field. It should appear up for all LECs ATM interfaces.
Step 7 Use the show epc if-entry interface command and test the CAM information between the egress Gigabit
Ethernet interface from the entry ATM interface.
Switch# show epc if-entry interface atm 10/0/0 entry gigabitEthernet 3/0/1
IF Entry for GigabitEthernet3/0/1 on ATM10/0/0
Mac(hex) - 00:90:21:41:88:38
isMyInteface : False isSubInterface : False
Status Up Broute VC - 322 Bcast VC - 0
Netmask: 24
FEC disabled
Trunking Disabled
State : Not-Applicable/Listening/Blocking
Bridge-Group disabled
IP routing on bridging off
IPX routing off bridging off
Appletalk routing off
In Encapsulation:
ICMP Redirect enabled Unreachable enabled
IP Multicast disabled: ttl-threshold: 0
Check the following:
• Broute VC field status is up.
• Note the Broute VC number. In this example, the Broute VC is “322.”
• IP routing is on.
Step 8 Use the show epc if-entry interface command and test the CAM information in the opposite direction
between the egress ATM interface from the entry Gigabit Ethernet interface.
Switch# show epc if-entry interface gigabitEtherenet3/0/1 entry atm 10/0/0.3
IF Entry for ATM10/0/0.3 on GigabitEthernet3/0/1
Mac(hex) - 00:90:21:41:88:17
isMyInteface : False isSubInterface : True
Status Up Broute VC - 67 Bcast VC - 0
Netmask: 25
FEC disabled
Trunking Disabled
State : Not-Applicable/Listening/Blocking
Bridge-Group disabled
