Error Reading Lacp Discovery Protocol Ca Spectrum

This section describes how to access standards-based awarding information in OneClick. Y'all can admission awarding models and the information related to them from the Information tab of the device or by using the search functionality in the Locater tab.

Admission Standards-Based Information Using the Information Tab

Depending on the device, you lot have modeled, you might accept various OneClick subviews available to you from the Information tab in the Component Particular panel. From these subviews, you lot can view awarding model information.

To access standards-based information from a specific device model

Select the device from which you want to view RFC information.

In the Component Details panel, in the Information tab, expand the subview containing the information that you desire to review.

Diverse subviews are available depending on what MIB standards the device supported when it was modeled.

Yous can utilise the search functionality in the Locater tab to find application models and to subsequently view awarding model information. Search results appear in the Results tab of the Contents panel. Detailed information for application models that are selected in the results list appears in the Component Particular panel.

Search for Application Models

If you are not sure which device to access for the awarding models you desire to view, y'all can utilise the search functionality of the Locater tab to listing every awarding model that was created and to which you have access rights.

If you are operating a Distributed SpectroSERVER (DSS) environment, some searches require yous to select which landscapes to include in your search from the 'Select Landscapes to Search' dialog.

To admission awarding models using Locater search

Click the Locater tab in the Navigation panel.

In the Locater tab, in the Name column, click 'Application Models' to expand it, and then do 1 of the following:

Double-click 'All Application Models.'

Click 'All Application Models,' and then click the 'Create a new search' button.

Enter any additional information if prompted, depending on the blazon of search you are running, and click OK.

If additional input is not required, the search runs immediately and the search results appear in the Results tab of the Contents panel.

To narrow your search, enter further criteria in the Filter box at the elevation of the results listing in the Results tab.

For example, if you lot were looking for the Repeater awarding, you could enter

1516

 in the Filter box, which would detect the Repeater model by its Model Blazon Name, 'rfc1516App.' Alternatively, you could enter

repeater

 in the Filter box, which would find the Repeater model by its Name, '

<device_name>

_SNMP-Repeater.'

The Results tab refreshes to show but those models that lucifer the criteria in the Filter box.

In the Results tab list, select the application model y'all want more information about.

The Component Detail view displays details about the selected application model.

Click any of the available tabs in the Component Detail view to review data specific to the selected awarding model.

For more information about using Locater search functionality, run across Using OneClick.

IEEE 802.3ad-based link assemblage lets you amass ii or more links together to course Link Aggregation Groups (LAGs), such that a MAC customer considers LAG as a single link. CA Spectrum supports LACP (Link Aggregation Control Protocol) with the post-obit features:

Locater Search

Spotlight View

Threshold Alarm

The LACP Port Aggregation table contains Link Aggregation Control configuration information of every Aggregation Port associated with a device.

The following attributes are available in the LACP Port Assemblage Table:

Aggregator ID

Indicates the ID number as the base of operations port number or everyman number of an aggregator. Each aggregator must have an ID number. For example, an aggregator with ports 12, 16, and 17 must exist assigned the ID number 12 because that is the base port number.

Actor Port

Indicates a port number that is assigned to the port by the actor, encoded every bit an unsigned integer.

Partner Port

Indicates a port number that is associated with the link assigned to the port by the partner, encoded every bit an unsigned integer.

Thespian MAC Address

Defines the value of the organization ID for the system that contains the Assemblage Port.

Default:

 Six-digit MAC accost.

Partner MAC Accost

Represents the current value of the Aggregation Port protocol.

Default:

 Six-digit MAC address.

Thespian Port Operational Country

Indicates the operational values of Actor_State, transmitted past the role player in the Link Aggregation Control Protocol Data Units (LACPDU).

Partner Port Operational State

Indicates a cord of 8 bits, corresponding to the current values of Actor_State in the most recently received LACPDU transmitted by the protocol Partner. In the absence of an active protocol partner, this value might reflect the manually configured aAggPortPartnerAdminState value.

Actor Port System Priority

Defines the priority value that is associated with the Thespian Organization ID.

Default:

 Two-digit MAC address.

Partner Port System Priority

Indicates the current administrative value of the port priority for the protocol partner.

Private or Aggregated Port

Represents a Boolean value of the Aggregation Port. This value indicates whether the Aggregation Port tin can Aggregate (TRUE) or tin can only operate as an Individual link (Simulated).

The post-obit epitome displays the LACP Port Aggregation Table that is available in OneClick:

The port aqueduct assemblage is displayed in the Interfaces tab of OneClick. The port channel is displayed as a sub-interface of aggregated Ethernet interfaces in the Interface tab. The LACP configured port channels are of type ieee8023adLag.

The post-obit image displays the Interfaces tab of a device configured for LACP.

In case of VLAN tagging enabled on top of LACP configuration, the port channel is displayed separately and not every bit a sub-interface of aggregated Ethernet interfaces in the Interface tab of OneClick.

The post-obit image displays the Interface tab in case of VLAN tagging enabled:

You lot can utilize the search functionality in the Locater tab to find the devices that are configured with LACP and the application models that are associated with LACP. Search results appear in the Results tab of the Contents console. Detailed information for application models that are selected in the results list appears in the Component Detail panel. Access LACP Locater search from the Locater tab of the Navigation

Open the CA Spectrum OneClick Console.

From the Navigation Panel, Click the Locater tab.

The Search Options window opens.

Select Devices, Supports Application, and LACP.

The LACP Locater Search results are displayed in Contents panel.

You lot can use the Spotlight feature in OneClick to view the devices that are configured with LACP on your network.

The post-obit epitome displays the LACP Devices List option that is available in Spotlight View:

You can spotlight the listed items if they have been enabled and configured on your network. You tin click the Spotlight View button that is available on the Topology toolbar and tin can select the LACP Devices Listing option to display the LACP configured devices.

LACP Threshold Computation

Spectrum generates various LACP threshold violation alarms on the LACP port channel model, such as critical, major, and minor. All the physical interfaces that are aggregated to the logical port of LACP participate in threshold calculation. Yous can use this threshold alarm to know the usage of the physical interfaces in an aggregate grouping of LACP.

The LACP threshold is calculated based on the IfOperStatus of the aggregated interfaces. To access IfOperStatus, y'all must have the admin link (based on external attribute, ifAdminStatus) status as Upward.

          
downwards/totallinks          
        

The following scenarios are considered during the threshold comparisons:

If the LACP_IF_Port attributes are set to a value other than 0 but not greater than 100, the following attributes are used during the threshold comparisons:

LACP_Critical_Threshold = 0x2202c0

LACP_Major_Threshold = 0x2202bf

LACP_Minor_Threshold = 0x2202be

If the LACP_IF_Port attributes are set to 0 or less than 0 or greater than 100, the following VNM attributes values are used during the threshold comparisons:

Critical_Threshold = 0x0001321e

Major_Threshold = 0x0001321d

Minor_Threshold = 0x0001321c

If all the LACP port level attributes are set to 0 and the VNM LACP threshold attributes are set to greater than 100, no threshold is calculated.

Condition Correlation of LACP ports

Starting from CA Spectrum 10.2.2 release, the LACP threshold violation alarms functionality is enhanced to avert multiple contained alarms (on port and port channel) for bad links. With this enhancement, the alarms generated on the ports that are part of an LACP assemblage are correlated and suppressed. Simply the LACP threshold violation alarms are generated on the port channels and the alarms generated on the ports are suppressed and shown equally symptoms.

Symptom

The LACP Port Aggregation Table does not contain Link Aggregation Command configuration information of every Aggregation Port associated with a device.

Verify the values in the dot3adAggPortAggregateOrIndividual table in IEEE8023-LAG-MIB. This indicates whether a port is attached to an LACP channel. If the port is attached to an LACP channel, the value tin can be True, otherwise the value can be FALSE.

Verify the values in the dot3adAggPortAttachedAggID table in IEEE8023-LAG-MIB. Spectrum uses this table to get the aggregated port details.

Symptom

For Cisco devices, the LACP port aqueduct type is displayed wrongly. It is displayed as propVirtual instead of ieee8023adLag in Interfaces tab of OneClick.

Solution

Configure the 'IsLACP_PropVirtual=true in. vnmrc' file, and then delete and rediscover the devices. If in that location are multiple devices, use the LACP migration script.

Symptom

The Lacp_HASPART associations are not created correctly for LACP configured port channels.

Solution

Verify whether LACP is correctly configured on the device and whether the values are correct in the dot3adAggPortAttachedAggID table in IEEE8023-LAG-MIB. Spectrum uses this tabular array to get the aggregated port details.

Symptom

The LACP threshold violation alarms are not getting generated correctly.

Solution

Verify whether the Lacp_HASPART associations are correctly created for LACP configured port channels. There should be Lacp_HASPART clan that are created between:

 i) the device (left model handle) and port channel (correct model handle).

ii) the port channel (left model handle) and the aggregated physical interfaces (right model handle).

Symptom

The link information tab is non displaying all the links correctly.

Solution

Verify whether the CDP/LLDP is configured correctly for the device. For instance, following are the OIDs Spectrum checks in instance of Juniper devices in which LLDP is configured.

ane.0.8802.one.1.two.1.3.7.i.2 (lldpLocPortIdSubtype)

i.0.8802.1.ane.2.1.iii.vii.one.iii (lldpLocPortId)

1.0.8802.one.1.2.ane.iii.7.1.four (lldpLocPortDesc)

In case, the in a higher place troubleshooting did non help to resolve the problem, enable the following logging.

Enable the LACP logging on SpectroSERVER by adding the configuration lacp_debug=true in the .vnmrc file. This change requires a SpectroSERVER restart.

After enabling the above logging, reproduce the issue and collect the VNM.out file.

Accept an attributes dump of the LACP awarding model associated with the problematic device. To observe the associated LACP application model, click Locator Search -> Application Models -> By Device Proper noun. After listing the application models associated with the device, filter the listing by 802dot3adApp.

Reconfigure LACP-Enabled Interface Models

When you upgrade CA Spectrum nine.3 to CA Spectrum x.0, the LACP modeling requires deletion and rediscovery of the affected models.  To eliminate the trouble of manually deleting and re-discovering the effected models, run the RecreateLACPModels.pl script, which migrates the LACP configured devices without whatsoever problem.

ane) Identify the LACP configured devices by reading the LACP mib (IEEE8023-LAG-MIB).

2) Delete the LACP configured interfaces/port channels and model them correctly.

Later the migration, follow these steps to run the script:

Copy the downloaded script to $SPECROOT

Prepare the IsLACP_PropVirtual=truthful in the vnmrc file, which is located at $SPECROOT\SS

To Run the script manually, connect to the bash prompt where the SpectroSERVER installed

Get to the $SPECROOT Directory (cd /c/win32app/Spectrum)

Run the script (RecreateLACPModels.pl) using the Perl

For your reference, following is a sample output of the RecreateLACPModels.pl command.
