ATM PVC F5 OAM Recovery Traps
The ATM PVC F5 OAM Recovery Traps feature introduces Simple Network Management Protocol (SNMP) traps that notify the administrator when a permanent virtual circuit (PVC) has recovered from F5 Operation, Administration, and Maintenance (OAM) end-to-end loopback failures, and F5 OAM alarm indication signal/remote defect indication (AIS/RDI) failures.

Prerequisites for ATM PVC F5 OAM Recovery Traps
Extended ATM PVC up and down traps and ATM PVC traps for, OAM F5 AIS/RDI, and OAM F5 loopback failures and recoveries cannot be used at the same time as the legacy ATM PVC trap. The legacy ATM PVC trap must be disabled by using the no snmp-server enable traps atm pvc command before extended ATM PVC up and down traps and ATM PVC traps for OAM F5 CC, OAM F5 AIS/RDI, and OAM F5 loopback failures and recoveries can be configured.
OAM management must be enabled on the PVC before you can use any ATM PVC traps.
Restrictions for ATM PVC F5 OAM Recovery Traps
The F5 OAM recovery traps are supported for ATM PVCs only.

F5 OAM Recovery Traps for ATM PVCs
F5 OAM cells are used to detect connectivity failures and recoveries at the ATM layer. Before the introduction of this feature, Cisco IOS software provided support for SNMP traps (also called SNMP notifications) for F5 end-to-end loopback, and F5 AIS/RDI connectivity failures on a PVC. The ATM PVC F5 OAM Recovery Traps feature introduces SNMP traps that notify the network management system (NMS) when connectivity is restored to a PVC after the following types of failures:
•F5 OAM end-to-end loopback failures
•F5 OAM segment AIS/RDI failures
•F5 OAM end-to-end AIS/RDI failures
Information in the traps includes the number of PVCs that recovered and time stamps indicating when the first and last recoveries occurred during the notification interval.
To limit the amount of traffic that can be generated by the F5 OAM failure and recovery traps, only one trap of each type can be generated in each trap interval. Each trap can report on multiple PVCs, and successive PVCs that have the same failure or recovery are reported as a range.
In addition to the traps, MIB tables are maintained to provide information about the failures and recoveries on PVCs.
For a complete description of the extended ATM PVC Trap MIB, including the supported notifications and tables, see the MIB file called CISCO-ATM-PVCTRAP-EXTN-MIB.my, available through Cisco.com at the following URL:
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml
Benefits of F5 OAM Recovery Traps for ATM PVCs
Before the introduction of this feature, when F5 OAM failures were detected on PVCs, failure notifications were sent to the NMS, and the operational state of the PVC was kept up. There was no mechanism for notifying the NMS when connectivity was restored to the PVCs after F5 OAM failures. The F5 OAM Recovery Traps feature introduces traps that asynchronously notify the NMS when PVCs have recovered from F5 OAM failures.
How to Configure F5 OAM Recovery Traps for ATM PVCs
•Enabling OAM F5 Failure and Recovery Traps for ATM PVCs
Configuring ATM OAM Support
Perform this task to configure ATM OAM support on an ATM PVC.
SUMMARY STEPS
1. enable
2. configure terminal
3. interface atm number
4. ip address ip-address mask
5. pvc [name] vpi/vci
6. oam-pvc manage [keep-vc-up [end aisrdi failure | seg aisrdi failure]]
DETAILED STEPS
Enabling OAM F5 Failure and Recovery Traps for ATM PVCs
Perform this task to enable the MIB and SNMP notifications that support ATM OAM F5 CC management.
SUMMARY STEPS
1. enable
2. configure terminal
3. snmp-server enable traps atm pvc extension {up | down | oam failure [aisrdi | loopback]}
DETAILED STEPS
Troubleshooting Tips
Use the show running-config command to verify the configuration of ATM OAM management.
Use the show atm pvc command to verify that ATM OAM management is enabled and to display the state of the PVC.
Use the debug snmp packet command to display which SNMP traps are being generated.
Configuration Examples for ATM PVC F5 OAM Recovery Traps
•Enabling OAM PVC Managment: Example
•ATM PVC Extended Up and Down Notifications: Example
•ATM OAM Failure Looback Notification: Example
Enabling OAM PVC Managment: Example
The following example shows how to enable ATM PVC OAM management.
Router(config)# interface ATM0/3/0.100 point-to-point
Router(config-subif)# pvc pvc100 0/100
Router(config-if-atm-vc)# oam-pvc manage
Router(config-if-atm-vc)# end
Note Enhanced Interior Gateway Routing Protocol (EIGRP) must be configured on the router if you want the notification packets to be sent to the NMS.
ATM PVC Extended Up and Down Notifications: Example
Enabling ATM PVC extended up and down notifications: Example
The following example shows how to enable ATM PVC extended up and down notifications:
snmp-server community public RW
snmp-server host 172.16.61.90 public
snmp-server enable traps atm pvc extension up
snmp-server enable traps atm pvc extension down
snmp-server host 10.0.0.115 vrf Mgmt-intf version 2c public udp-port 2030
ATM PVC Down Notification: Example
The following sample output shows an ATM PVC in the DOWN state:
Router# show atm vc
Codes: DN - DOWN, IN - INACTIVE
VCD / Peak Av/Min Burst
Interface Name VPI VCI Type Encaps SC Kbps Kbps Cells St
0/3/0.100 pvc100 0 100 PVC SNAP UBR 149760 DN
The following example shows the corresponding output for the ATM PVC extended down notification:
Received SNMPv2c Trap:
Community: public
From: 10.0.0.54
sysUpTimeInstance = 1918435
snmpTrapOID.0 = catmIntfPvcDownTrap
ifIndex.52 = 52
atmIntfPvcFailures.15 = 4
atmIntfCurrentlyFailingPVcls.15 = 1
ifDescr.52 = ATM0/3/0.100
catmPVclCurFailTime.52.0.100 = 1915435
catmPVclPrevRecoverTime.52.0.100 = 259552
catmPVclFailureReason.52.0.100 = catmLoopbackOAMFailure(1)
ATM PVC Up Notification: Example
The following sample output shows an ATM PVC in the UP state:
Router# show atm vc
Codes: DN - DOWN, IN - INACTIVE
VCD / Peak Av/Min Burst
Interface Name VPI VCI Type Encaps SC Kbps Kbps Cells St
0/3/0.100 pvc100 0 100 PVC SNAP UBR 149760 UP
The following example shows the corresponding output for the ATM PVC extended up notification:
Received SNMPv2c Trap:
Community: public
From: 9.0.0.54
sysUpTimeInstance = 1933376
snmpTrapOID.0 = catmIntfPvcUp2Trap
ifIndex.52 = 52
catmIntfCurrentlyDownToUpPVcls.15 = 1
ifDescr.52 = ATM0/3/0.100
catmPVclCurRecoverTime.52.0.100 = 1930676
catmPVclPrevFailTime.52.0.100 = 1915435
catmPVclRecoveryReason.52.0.100 = catmLoopbackOAMRecover(1)
ATM OAM Failure Looback Notification: Example
Enabling ATM OAM Failure Loopback Notification: Example
The following example shows how to enable ATM PVC OAM failure loopback notifications and extended up and down notifications:
snmp-server community public RW
snmp-server enable traps atm pvc extension up
snmp-server enable traps atm pvc extension down
snmp-server enable traps atm pvc extension oam failure loopback
snmp-server host 10.0.0.115 vrf Mgmt-intf version 2c public udp-port 2030
Note If you configure the snmp-server enable traps atm pvc extension oam failure command, you may not see up or down traps when an OAM failure trap is generated. Additionally, the PVC will stay in the UP state.
OAM Loopback Failure Notification: Example
The following sample output shows an ATM PVC that has failed. Note that the output indicates the PVC is still in the UP state.
Router# show atm vc
Codes: DN - DOWN, IN - INACTIVE
