Feature Information for Configuring ATM PVC F5 OAM Recovery Traps

Configuring ATM PVC F5 OAM Recovery Traps

First Published: August 26, 2003

Last Updated: November 20, 2009

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.

The ATM PVC TRAP Enhancement for Segment and End AIS / RDI failures feature adds Segment and End AIS/RDI Failure notification (traps) to the existing ATM PVC trap infrastructure.

Prerequisites for Configuring ATM PVC F5 OAM Recovery Traps

•Extended ATM PVC up and down traps and ATM PVC traps for OAM F5 Continuity Check (CC), OAM F5 AIS/RDI, and OAM F5 loopback failures and recoveries cannot be used at the same time as legacy ATM PVC traps.

•Legacy ATM PVC traps must be disabled by using the no snmp-server enable traps atm pvc command before 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. If the extended ATM PVC traps or ATM OAM F5 CC traps are enabled, you must disable them by using the no snmp-server enable traps atm pvc extension command before you can enable legacy ATM PVC traps.

•OAM management must be enabled on the PVC before you can use any ATM PVC traps.

Restrictions for Configuring ATM PVC F5 OAM Recovery Traps

•The F5 OAM recovery traps are supported for ATM PVCs only.

•The CISCO-ATM-PVCTRAP-EXTN-MIB is currently supported in Cisco IOS Release 12.0(27)S, Cisco IOS Release 12.2(33)SRE, Cisco IOS Release 15.0(1)M and later releases.

•The traps associated with CC are supported only on Cisco IOS 7500 series routers with PA-A3 and PA-A1 cards and Gigabit Switch Router (GSR).

Information About Configuring ATM PVC F5 OAM Recovery Traps

To configure ATM PVC F5 OAM recovery traps, you should understand the following concepts:

•F5 OAM Recovery Traps for ATM PVCs

•Benefits of F5 OAM Recovery Traps for ATM PVCs

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/go/mibs

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.

ATM PVC Trap Enhancements for Segment and End AIS/RDI Failures

ATM PVC trap support provides ATM PVC failure notification by sending a trap when a PVC on an ATM interface fails or leaves the UP operational state. F5 OAM cells are used to detect connectivity failures and recoveries at the ATM layer. The operator informs the NMS of these OAM failures using ATM PVC traps. The following ATM PVC Traps are supported:

•ATM PVC DOWN TRAP

•ATM PVC F5 Loop back failure TRAP

•ATM PVC F5 Segment CC failure TRAP

•ATM PVC F5 End-to-End CC failure TRAP

•ATM PVC F5 AIS/RDI failure TRAP

When connectivity is restored, the PVC state is brought UP for allowing data transfer to take place over the PVC. This connectivity restoration uses the OAM cells. The following recovery traps are used to inform the NMS about the restoration of connectivity:

•ATM PVC UP TRAP

•ATM PVC F5 Loop back recovery TRAP

•ATM PVC F5 Segment CC recovery TRAP

•ATM PVC F5 End-to-End CC recovery TRAP

•ATM PVC F5 AIS/RDI recovery TRAP

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.

The ATM PVC Trap Enhancements for Segment and End AIS/RDI failures feature addresses the issue of generating the separate ATM F5 segment and end AIS/RDI failure and recovery traps.

Benefits of the ATM PVC Trap Enhancements for Segment and End AIS/RDI Failures Feature

The ATM PVC TRAP Enhancement for Segment and End AIS/RDI Failures feature adds segment and end AIS/RDI Failure notification (traps) to the existing ATM PVC trap infrastructure. This feature adds the ifDescr object to the existing traps. The addition of this object allows the operator to get the interface name directly from the trap. The segment and end AIS/RDI failure and recovery traps are generated when AIS/RDI failure traps are enabled.

•Use the debug snmp packet command to display which SNMP traps are being generated.

Configuration Examples for Configuring ATM PVC F5 OAM Recovery Traps

•Enabling OAM PVC Managment: Example

•ATM PVC Extended Up and Down Notifications: Examples

ATM OAM Failure Looback Notification: Examples

Enabling ATM OAM Failure Loopback Notification
The following example shows how to enable ATM PVC OAM failure loopback notifications and 
extended up and down notifications:
Router(config)# snmp-server community public RW
Router(config)# snmp-server enable traps atm pvc extension up
Router(config)# snmp-server enable traps atm pvc extension down
Router(config)# snmp-server enable traps atm pvc extension oam failure loopback
Router(config)# 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

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
