Trap Support - ContivityVPN

There are two possible trap support configurations that you can use for the Nortel ContivityVPN devices. The default configuration generates an event and sometimes an alarm when one of the supported traps is received. The alternative configuration tracks the rate at which some traps are received, and only generates an alarm if the number of traps exceeds a specified threshold within a certain time frame.

Trap Processing

When determining the Event ID that should be generated, the intelligence for the ContivityVPN takes into consideration not only the trap OID but also the Alarm Severity varbind sent along with the trap. This allows for a finer resolution of Event ID generation and provides a better alarm criticality assignment to the device model.

Table 3: Nortel Contivity Traps [Page 14] shows the events and alarms created by traps defined in the Nortel CONTIVITY-TRAPS-V1-MIB. This is the default trap support configuration.

Table 4: Contivity Event Frequency Table [Page 22] shows the Event Frequency [Page 21] rules for the Nortel Contivity devices. This trap support is based on the rate at which certain traps are received.

Note: See the Nortel CONTIVITY-TRAPS-V1-MIB for descriptive information about these traps.

Notes

Unexpected

SPECTRUM Events and Alarms are generated based on the Trap Varbind Alarm Severity. For each Contivity trap, the potential alarm severities that can be sent are listed. If an unexpected Alarm Severity is sent for a particular trap, an unexpected Alarm Severity event is generated.

Link Up / Link Down Traps For ContivityVPN Model Types

Nortel Contivity Extranet Switches have Link Up / Link Down Trap Enabled options for BranchOffice Nailed-Up Tunnels and BranchOffice OnDemand Tunnels that you can set. These options are located under the ADMIN > SNMP Traps menu option of the Nortel Contivity web administration application (Web Administration [Page 46]). To change these options, click the “Configure” button in the Standard IETF section. It is recommended that you leave these options enabled. However, due to the filtering out of interfaces of type tunnel (131), critical alarms will not be mapped to these traps.

Event Frequency

An alternative Event Disposition file is available to use for processing events. This file contains rules that create an alarm if a certain number of events are received within a specified window of time. These rule apply to some, but not all of the events generated. Table 4 outlines how events are processed with this alternative Event Disposition file.

Note: MINOR Alarm mappings (Yellow) were removed from the Rules based EventDisp file.

To configure SPECTRUM to do this:

1. Navigate to the <$SPECROOT>/SS/CsVendor/NortelVPN directory.

2. Find the file named EventDisp. Change the name of this file to EventDisp.norules.

3. Navigate to the <$SPECROOT>/SS/CsVendor/NortelVPN/Rules directory and find the file named EventDisp.rules.

4. Copy this file into the <$SPECROOT>/SS/CsVendor/NortelVPN directory. Change the name of this file to EventDisp.

Tunnel Interface Filtering

This section describes the Tunnel Interface Filter Functionality added for Nortel Contivity devices.

Purpose

The ContivityVPN device populates the ifTable with both user and branch VPN tunnel interface entries. However, it is possible for thousands of user VPN tunnel interfaces to exist. The ContivityVPN interface filtering functionality was introduced to selectively filter out user tunnel interfaces and prevent unnecessary modeling of these interfaces.

Note: Tunnel interface filtering is only available for models of type ContivityVPN.

Enabling and Disabling Tunnel IF Filtering

Tunnel IF filtering (enabled by default in SPECTRUM 6.6 original release) can be disabled or enabled by following the procedure below.

Note: If this setting is changed in the SpectroSERVER database prior to installing the Service Pack 3 enhancement, the tunnel interfaces modeled as Serial_IF_Ports will not be converted automatically to Tunnel_If models upon upgrading. See Reconfiguring Existing Device Models [Page 43].

Procedure

Note: This procedure only applies to SPECTRUM 6.6 releases prior to Service Pack 3.

1. In the Model Type Editor, set the default list value for attribute If_Mtype_Map handle 0x011fb4. Looking at the list of values, locate OID instance 131.

2. It should be set to a value of 0. Setting it to zero will prevent the interface type from being modeled.

3. To disable tunnel interface filtering and allow these models to be created, set this value to 220013.

Contivity Enhancements for 6.6 Service Pack 3

This section summarizes the enhancements made with 6.6 Service Pack 3 for the Nortel Contivity Management Module.

Modeling of Tunnel Interfaces

Creation of models to represent site-to-site or branch tunnel interfaces is now controlled by the Create Sub-Interface attribute of the Contivity device model. This can be set from the Configuration tab of the Global Attribute Editor, or from the Redundancy and Model Reconfiguration Options GIB on an individual model. (No models are ever created to represent "user" tunnels. This behavior is consistent with the previous version.)

Tunnel Interface "Stacking"

Tunnel interface models are created as sub-interfaces of the physical interface whose IP address matches the tunnel's local address as indicated in the Tunnel MIB. Since Contivity devices don't support the ifStackTable, this mechanism of determining the lower-layer interface is necessary and effective.

Automatic Connectivity Mapping

When a tunnel interface model activates for the first time (i.e. during initial device modeling or during an interface reconfiguration), SPECTRUM will search for a tunnel interface model representing the other end-point of the tunnel. If such a model is found, the connection between these two interfaces is modeled. SPECTRUM uses the local address and remote address indicated in the Tunnel MIB (rfc2667) to find the other end-point of the tunnel.

Document 5126

Interface Model Identification

Tunnel interface models are now identified uniquely by their local address and remote address as indicated in the Tunnel MIB (rfc2667). This enables SPECTRUM to preserve the interface model even if the ifIndex of the interface changes.

Interface Model Aging

During an interface reconfiguration, any interface model that no longer has a representation in the MIB is marked as "stale" instead of being destroyed. This feature enables SPECTRUM to retain the connectivity modeling between tunnel interfaces and other devices while the tunnel is down. The connectivity information can then be leveraged for event correlation and fault suppression.

On subsequent reconfigurations, the port age out time of the device model is compared with how long the interface model has been stale. If the interface does not reappear in the MIB, the interface model will be destroyed after it has aged out. If the interface does reappear in the MIB, then the interface model will be marked as current. The port is marked as stale by setting the "isStale" attribute to TRUE. The port age out time can be set per device by setting the "PortAgeOutTime" on the device to the number of minutes desired. The default age out time for the Contivity is two hours (120 minutes).

Link Down Trap Correlation

In an effort to reduce multiple alarms for a single network outage, link down traps for "tunnel" interface models are correlated with other conditions. The alarm for the link down trap will be suppressed if the lower layer (i.e. physical interface) is down. Also, if the "Suppress Linked Port Alarms" setting of the Live Pipes model is set to TRUE, the alarm for the link down trap will be suppressed if either of the following conditions are met:

1. The connected device is unreachable (by the SpectroSERVER)

2. The "linked" tunnel interface model is alarmed (RED)

Document 5126

Status Monitoring of Tunnel Interfaces

On the Contivity, the ifOperStatus of a tunnel interface entry is always "UP", right up to the point when it disappears from the ifTable. If a tunnel model becomes "stale", and no link down trap has yet been processed for the tunnel, SPECTRUM will generate a red alarm on the model. However, this alarm will be suppressed in the same cases in which a link down trap alarm would be suppressed, that is if the lower layer (i.e. physical interface) is down. Also, if the "Suppress Linked Port Alarms" setting of the Live Pipes model is set to TRUE, this alarm will be suppressed if either of the following conditions are met:

1. The connected device is unreachable (by the SpectroSERVER)

2. The "linked" tunnel interface model is alarmed (RED)

Recommendations for Management of Contivity Devices with SPECTRUM

Some changes to both the Contivity management settings and the SPECTRUM configuration settings may be required to achieve the best possible management of Contivity-based VPNs.

Contivity Management Settings

The following Contivity settings are recommended.

Enable Tunnel MIB

Aprisma recommends that the Tunnel IP MIB be enabled on all managed Contivity devices. This allows SPECTRUM to create models to represent the tunnel end points on the device. This MIB can be enabled/disabled from the ADMIN->SNMP section of the Contivity web management pages.

Enable Link Up/Down Traps

Aprisma recommends that link up and link down traps are enabled for physical interfaces and for "Nailed-Up" branch tunnels. This will give SPECTRUM more immediate notification of link state changes. Our experience has shown that link traps for "OnDemand" tunnels don't provide much value. The tunnel must be down for 15 minutes or so before the trap is sent.

Nail-Up Your Monitored Tunnels

Aprisma recommends that all tunnels for which connection monitoring is important be "Nailed-Up". SPECTRUM will not alarm "OnDemand" tunnels when they go down. Specifically, the Alarm on LINK down Trap attribute of the Tunnel_If model determines whether it will respond to link down traps or changes to the isStale attribute. A value of Always (1) will cause SPECTRUM to process these events; a value of Never (0) will cause SPECTRUM to ignore them. When SPECTRUM creates Tunnel_If models for the Contivity, it will set this attribute to Always for "Nailed-Up" branch tunnels, and Never for "OnDemand" tunnels. The Alarm on LINK down setting can be changed from the Configuration tab of the Global Attribute Editor, but we recommend you leave it as SPECTRUM has set it.

Document 5126

SPECTRUM Management Settings

The following SPECTRUM management settings are recommended.

Automatically Reconfigure Interfaces

Set this attribute to TRUE for Contivity models if you want SPECTRUM to manage the branch tunnels of the device. For devices that only support "User" tunnels, this setting should be FALSE. When TRUE, SPECTRUM will reconfigure the interface models whenever the ifNumber object of the device's SNMP agent changes.

Reconfigure on LINK change

Aprisma recommends this attribute be set to FALSE for all Contivity models. When set to TRUE, SPECTRUM performs an interface reconfiguration after every link up or link down trap received.

Discovery after Reconfigure

Aprisma recommends this attribute be set to FALSE (the default setting) for all Contivity models. SPECTRUM will model connections between newly found tunnels regardless of this setting. SPECTRUM's Autodiscovery process can add little or no value after most link state changes, especially for the Contivity devices, for which, most link state changes will represent tunnels coming up and going down, and not new router or bridge ports being configured.

Create Sub-Interfaces

Set this attribute to TRUE for Contivity models if you want SPECTRUM to monitor the branch tunnels. If this attribute is set to FALSE, SPECTRUM will not create models for the tunnel interfaces.

All of these settings can be modified using the Configuration tab of the Global Attribute Editor or the Redundancy and Model Reconfiguration Options GIB for a particular device model.

Suppress Linked Port Alarms

Aprisma recommends setting this attribute of the Live Pipes model to TRUE. This will suppress port alarms when either the connected device is unreachable or the linked port model is already alarmed. This setting can be modified from the Live Pipes Model Information View, which can be accessed from the VNM model's Configuration GIB.

Two Link Down Traps For One Down Tunnel

In this scenario (Figure 2), the SpectroSERVER retains contact to all managed elements in this meshed environment, but a tunnel between two devices goes down. SPECTRUM receives two link down traps. One tunnel interface is alarmed; the other is suppressed.

Loss of Contact and Link Down Trap

In this scenario (Figure 3), SPECTRUM loses contact with a "spoke" Contivity in a hub and spoke network. SPECTRUM also receives a link down trap from the hub, indicating the tunnel to the lost device. SPECTRUM alarms the lost device and suppresses the alarm on the tunnel interface indicated by the trap.

Physical Port Down, Loss of Contact, and Link Down Traps

In this scenario (Figure 4), a physical port of a Contivity goes down or loses its link to the public network. SPECTRUM gets link down traps for the physical port and tunnels of the Contivity, and loses contact with remote Contivity devices. The link down alarms on the tunnel interface models are suppressed, however SPECTRUM's fault isolation will create red alarms on the lost Contivity device models because they have an "up" neighbor. In a future release, SPECTRUM will suppress these alarms and the impact of the physical port alarm will include these lost devices.

Loss of Contact to Whole Network

In this scenario (Figure 5), SPECTRUM loses contact to the entire VPN network. SPECTRUM's fault isolation suppresses all but one loss of contact alarms.

66 SP3 Upgrade Considerations

This section describes possible upgrade considerations for the Contivity Management Module for SPECTRUM 66 SP3.

Reconfiguring Existing Device Models

Because of changes to the way tunnel interfaces are modeled, Aprisma recommends forcing an interface reconfiguration for all existing Contivity device models. This can be done using the Search Manager. First, find by model type all Contivity models. Select all desired models, and click on Manage > Reconfigure. It is strongly recommended that Discovery after Reconfigure be set to FALSE prior to forcing reconfigurations in this manner.

In the original release of SPECTRUM 6.6, the Contivity MM was configured with a setting that prevented tunnel interfaces from being modeled. The procedure described in Enabling and Disabling Tunnel IF Filtering [Page 31] shows how to change this setting so that Serial_IF_Port models are created for each tunnel interface. If this setting has been changed in the SpectroSERVER database prior to installing the Service Pack 3 enhancement, the tunnel interfaces modeled as Serial_If_Ports will not be converted automatically to Tunnel_If models upon upgrading. Aprisma recommends that these interface models be destroyed prior to initiating reconfigurations on the device models.

Known Anomalies

This section describes known anomalies for the Contivity Management Module for SPECTRUM 66 SP3.

Create Sub-Interface Changes

If Create Sub-Interfaces is changed from TRUE to FALSE for a Contivity model after tunnel interface models have been created, a subsequent interface reconfiguration will cause the tunnel interface models to go stale and start aging out, rather than being destroyed immediately. In an environment in which tunnel monitoring is desired for some, but not all, Contivity devices, it may be desirable to set the default value of Create Sub-Interfaces for the Contivity model type to FALSE. Once you have set this value to FALSE, set Create Sub-Interfaces to TRUE for the individual models of Contivity devices for which tunnel monitoring is desired.

Autodiscovery and Public Addresses

It is generally the case that the public addresses on the Contivity devices in a VPN will be in different subnets because they will be separated by several Internet routers. It is possible, however, to have Contivity devices with public interfaces on the same subnet. In this case, SPECTRUM's autodiscovery may attempt to map the connectivity of the public interfaces. The manifestation of this would be a LAN container in the same topology view as the Contivity models with pipes to the Contivity models. A fanout model without the LAN would be connected to the public interface models of the Contivities.

Port Aging is not Aggressive

When a tunnel goes away, the tunnel interface model is marked as "Stale". Any future reconfiguration that occurs after the "portAgeOutTime" of the device will cause that tunnel model to be destroyed. However, if there are no future reconfigurations of the device, the "Stale" tunnel interface model will stay around. For example, consider a polling interval of 5 minutes and a portAgeOutTime of 30 minutes. If a tunnel goes down at 10:27 and SPECTRUM polls at 10:30, SPECTRUM will detect an ifNumber change and perform and interface reconfiguration. During this process, the tunnel

Nortel Contivity VPN SwitchesManagement Module Guide

Page 45

Document 5126

interface will be marked as stale. You may expect that, if the tunnel doesn't come back up, the tunnel interface model will be destroyed at 11:00 precisely. However, if ifNumber does not change again for a week, interface reconfiguration won't run again for a week, and this tunnel interface model will remain stale until this time. Then, it will be destroyed.

Web Administration

The Nortel web-based administration application can be launched from the Nortel Contivity device model.

To launch the web management view for the Nortel Contivity devices, right click on the device icon of the device model in the Topology view and choose Web Administration.

Note: By default, the Web Admin URL is http://<0x1027f> (the Network_Address attribute). You can use the Global Attribute Editor in Search Manager to change this. See the Global Attribute Editor section of the Search Manager User Guide (2383) for more information.
