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.

Information About ATM PVC F5 OAM Recovery Traps

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.

      Troubleshooting Tips

      To troubleshoot PPP sessions establishment, use the following commands:

      • debug ppp authentication
      • debug ppp negotiation

      To troubleshoot the establishment of PPP sessions that are authenticated by a RADIUS or TACACS server, use the following commands:

      • debug aaa authentication
      • debug aaa authorization

      Caution

      Use debug commands with extreme caution because they are CPU-intensive and can seriously impact your network.

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

          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

          The following example shows the corresponding output for the ATM PVC extended up notification:

          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 
           VCD /                                            Peak Av/Min Burst

          The following example shows the corresponding output for the OAM loopback failure notification:

          Received SNMPv2c Trap:

catmPVclStatusChangeEnd.52.0.100 = 1961155

          OAM Loopback Recovery 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

          ATM PVC F5 OAM Recovery Traps

          Cisco IOS XE Release 2.3

          The ATM PVC F5 OAM Recovery Traps feature introduces SNMP traps that notify the administrator when a PVC has recovered from F5 OAM end-to-end loopback failures and F5 OAM AIS/RDI failures.

          The following command was introduced: snmp-server enable traps atm pvc extension.
