Monitor the LLDP Service

LLDP is used by network devices for advertising their identity, capabilities, and neighbors on a LAN. You can view this information for one or more devices. You can also view the information at an earlier point in time or view changes that have occurred to the information during a specified time period. For an overview and how to configure LLDP in your network, refer to Link Layer Discovery Protocol.

NetQ enables operators to view the overall health of the LLDP service on a networkwide and a per session basis, giving greater insight into all aspects of the service. This is accomplished in the NetQ UI through two card workflows, one for the service and one for the session and in the NetQ CLI with the netq show lldp command.

Monitor the LLDP Service Networkwide

With NetQ, you can monitor LLDP performance across the network:

  • Network Services|All LLDP Sessions
    • Small: view number of nodes running LLDP service and number of alarms
    • Medium: view number of nodes running LLDP service, number of sessions, and number of alarms
    • Large: view number of nodes running LLDP service, number of sessions and alarms, number of sessions without neighbors, switches with the most established/unestablished sessions
    • Full-screen: view all switches, all sessions, and all alarms
  • netq show evpn command: view associated host interface, peer hostname and interface, and last time a change was made for each session running LLDP

When entering a time value in the netq show lldp command, you must include a numeric value and the unit of measure:

  • w: week(s)
  • d: day(s)
  • h: hour(s)
  • m: minute(s)
  • s: second(s)
  • now

When using the between option, the start time (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.

View Service Status Summary

You can view a summary of the LLDP service from the NetQ UI or the NetQ CLI.

Open the small Network Services|All LLDP Sessions card. In this example, the number of devices running the LLDP service is 14 and no alarms are present.

To view LLDP service status, run netq show lldp.

This example shows the Cumulus reference topology, where LLDP runs on all border, firewall, leaf, and spine switches, all servers, and the out-of-band management server. You can view the host interface, peer hostname and interface, and last time a change was made for each session.

cumulus@switch:~$ netq show lldp

View the Distribution of Nodes, Alarms, and Sessions

It is useful to know the number of network nodes running the LLDP protocol over a period of time and how many sessions are established on a given node, as it gives you insight into the amount of traffic associated with and breadth of use of the protocol. Additionally, if there are a large number of alarms, it is worth investigating either the service or particular devices.

Nodes which have a large number of unestablished sessions might be misconfigured or experiencing communication issues. This is visible with the NetQ UI.

To view the distribution, open the medium Network Services|All LLDP Sessions card.

In this example, we see that 13 nodes are running the LLDP protocol, that there are 52 sessions established, and that no LLDP-related alarms have occurred in the last 24 hours. If there was a visual correlation between the alarms and sessions, you could dig a little deeper with the large Network Services|All LLDP Sessions card.

To view the number of switches running the LLDP service, run:

netq show lldp

Count the switches in the output.

This example shows two border, two firewall, four leaf switches, four spine, and one out-of-band management switches, plus eight host servers are all running the LLDP service, for a total of 23 devices.

View the Distribution of Missing Neighbors

You can view the number of missing neighbors in any given time period and how that number has changed over time. This is a good indicator of link communication issues.

To view the distribution, open the large Network Services|ALL LLDP Sessions card and view the bottom chart on the left, Total Sessions with No Nbr.

In this example, we see that 16 of the 52 sessions are consistently missing the neighbor (peer) device over the last 24 hours.

View Devices with the Most LLDP Sessions

You can view the load from LLDP on your switches using the large Network Services|All LLDP Sessions card or the NetQ CLI. This data enables you to see which switches are handling the most LLDP traffic currently, validate that is what is expected based on your network design, and compare that with data from an earlier time to look for any differences.

To view switches and hosts with the most LLDP sessions:

  1. Open the large Network Services|All LLDP Sessions card.

  2. Select Switches with Most Sessions from the filter above the table.

    The table content is sorted by this characteristic, listing nodes running the most LLDP sessions at the top. Scroll down to view those with the fewest sessions.

To compare this data with the same data at a previous time:

  1. Open another large LLDP Service card.

  2. Move the new card next to the original card if needed.

  3. Change the time period for the data on the new card by hovering over the card and clicking .

  4. Select the time period that you want to compare with the current time. You can now see whether there are significant differences between this time period and the previous time period.

In this case, notice that their are fewer nodes running the protocol, but the total number of sessions running has nearly doubled. If the changes are unexpected, you can investigate further by looking at another time frame, determining if more nodes are now running LLDP than previously, looking for changes in the topology, and so forth.

To determine the devices with the most sessions, run netq show lldp. Then count the sessions on each device.

In this example, border01-02 each have eight sessions, fw1-2 each have two sessions, leaf01-04 each have 10 sessions, spine01-04 switches each have four sessions, server01-06 each have three sessions, and server07-08 and oob-mgmt-server each have one session. Therefore the leaf switches have the most sessions.

View Devices with the Most Unestablished LLDP Sessions

You can identify switches and hosts that are experiencing difficulties establishing LLDP sessions; both currently and in the past, using the NetQ UI.

To view switches with the most unestablished LLDP sessions:

  1. Open the large Network Services|All LLDP Sessions card.

  2. Select Switches with Most Unestablished Sessions from the filter above the table.

    The table content is sorted by this characteristic, listing nodes with the most unestablished LLDP sessions at the top. Scroll down to view those with the fewest unestablished sessions.

Where to go next depends on what data you see, but a few options include:

  • Change the time period for the data to compare with a prior time. If the same switches are consistently indicating the most unestablished sessions, you might want to look more carefully at those switches using the Switches card workflow to determine probable causes. Refer to Monitor Switch Performance.
  • Click Show All Sessions to investigate all LLDP sessions with events in the full screen card.

View LLDP Configuration Information for a Given Device

You can view the LLDP configuration information for a given device from the NetQ UI or the NetQ CLI.

  1. Open the full-screen Network Services|All LLDP Sessions card.

  2. Click to filter by hostname.

  3. Click Apply.

Run the netq show lldp command with the hostname option.

This example shows the LLDP configuration information for the leaf01 switch. The switch has a session between its swp1 interface and host server01 in the mac:44:38:39:00:00:32 interface. It also has a session between its swp2 interface and host server02 on mac:44:38:39:00:00:34 interface. And so on.

Switches or hosts experiencing a large number of LLDP alarms may indicate a configuration or performance issue that needs further investigation. You can view this information using the NetQ UI or NetQ CLI.

With the NetQ UI, you can view the switches sorted by the number of LLDP alarms and then use the Switches card workflow or the Events|Alarms card workflow to gather more information about possible causes for the alarms.

To view switches with most LLDP alarms:

  1. Open the large Network Services|All LLDP Sessions card.

  2. Hover over the header and click .

  3. Select Events by Most Active Device from the filter above the table.

    The table content is sorted by this characteristic, listing nodes with the most LLDP alarms at the top. Scroll down to view those with the fewest alarms.

Where to go next depends on what data you see, but a few options include:

  • Change the time period for the data to compare with a prior time. If the same switches are consistently indicating the most alarms, you might want to look more carefully at those switches using the Switches card workflow.
  • Click Show All Sessions to investigate all switches running LLDP sessions in the full-screen card.

To view the switches and hosts with the most LLDP alarms and informational events, run the netq show events command with the type option set to lldp, and optionally the between option set to display the events within a given time range. Count the events associated with each switch.

This example shows that no LLDP events have occurred in the last 24 hours.

cumulus@switch:~$ netq show events type lldp
No matching event records found

This example shows all LLDP events between now and 30 days ago, a total of 21 info events.

View All LLDP Events

The Network Services|All LLDP Sessions card workflow and the netq show events type lldp command enable you to view all of the LLDP events in a designated time period.

To view all LLDP events:

  1. Open the Network Services|All LLDP Sessions card.

  2. Change to the full-screen card using the card size picker.

  3. Click the All Alarms tab.

    By default, events are listed in most recent to least recent order.

Where to go next depends on what data you see, but a few options include:

  • Sort on various parameters:
    • by Message to determine the frequency of particular events
    • by Severity to determine the most critical events
    • by Time to find events that may have occurred at a particular time to try to correlate them with other system events
  • Open one of the other full-screen tabs in this flow to focus on devices or sessions
  • Export data to a file for use in another analytics tool by clicking and providing a name for the data file.
  • Return to your workbench by clicking in the top right corner.

To view all LLDP alarms, run:

netq show events [level info | level error | level warning | level critical | level debug] type lldp [between <text-time> and <text-endtime>] [json]

Use the level option to set the severity of the events to show. Use the between option to show events within a given time range.

This example shows that no LLDP events have occurred in the last three days.

cumulus@switch:~$ netq show events type lldp between now and 3d

Monitor a Single LLDP Session

With NetQ, you can monitor the number of nodes running the LLDP service, view neighbor state changes, and compare with events occurring at the same time, as well as monitor the running LLDP configuration and changes to the configuration file. For an overview and how to configure LLDP in your data center network, refer to Link Layer Discovery Protocol.

To access the single session cards, you must open the full-screen Network Services|All LLDP Sessions card, click the All Sessions tab, select the desired session, then click (Open Card).

Granularity of Data Shown Based on Time Period

On the medium and large single LLDP session cards, the status of the neighboring peers is represented in heat maps stacked vertically; one for peers that are reachable (neighbor detected), and one for peers that are unreachable (neighbor not detected). Depending on the time period of data on the card, the number of smaller time blocks used to indicate the status varies. A vertical stack of time blocks, one from each map, includes the results from all checks during that time. The results are shown by how saturated the color is for each block. If all peers during that time period were detected for the entire time block, then the top block is 100% saturated (white) and the neighbor not detected block is zero percent saturated (gray). As peers become reachable, the neighbor detected block increases in saturation, the peers that are unreachable (neighbor not detected) block is proportionally reduced in saturation. An example heat map for a time period of 24 hours is shown here with the most common time periods in the table showing the resulting time blocks.

View Session Status Summary

You can view information about a given LLDP session using the NetQ UI or NetQ CLI.

A summary of the LLDP session is available from the Network Services|LLDP Session card workflow, showing the node and its peer and current status.

To view the summary:

  1. Open the or add the Network Services|All LLDP Sessions card.

  2. Change to the full-screen card using the card size picker.

  3. Click the All Sessions tab.

  4. Select the session of interest, then click (Open Card).

  5. Locate the medium Network Services|LLDP Session card.

  1. Optionally, open the small Network Services|LLDP Session card to keep track of the session health.

Run the netq show lldp command with the hostname and remote-physical-interface options.

This example show the session information for the leaf02 switch on swp49 interface of the leaf01 peer.

View LLDP Session Neighbor State Changes

You can view the neighbor state for a given LLDP session from the medium and large LLDP Session cards. For a given time period, you can determine the stability of the LLDP session between two devices. If you experienced connectivity issues at a particular time, you can use these cards to help verify the state of the neighbor. If the neighbor was not alive more than it was alive, you can then investigate further into possible causes.

To view the neighbor availability for a given LLDP session on the medium card:

  1. Open the or add the Network Services|All LLDP Sessions card.

  2. Change to the full-screen card using the card size picker.

  3. Click the All Sessions tab.

  4. Select the session of interest, then click (Open Card).

  5. Locate the medium Network Services|LLDP Session card.

    In this example, the heat map tells us that this LLDP session has been able to detect a neighbor for the entire time period.

    From this card, you can also view the host name and interface, and the peer name and interface.

To view the neighbor availability for a given LLDP session on the large LLDP Session card:

  1. Open a Network Services|LLDP Session card.

  2. Hover over the card, and change to the large card using the card size picker.

    From this card, you can also view the alarm and info event counts, host interface name, peer hostname, and peer interface identifying the session in more detail.

View Changes to the LLDP Service Configuration File

Each time a change is made to the configuration file for the LLDP service, NetQ logs the change and enables you to compare it with the last version using the NetQ UI. This can be useful when you are troubleshooting potential causes for alarms or sessions losing their connections.

To view the configuration file changes:

  1. Open or add the Network Services|All LLDP Sessions card.

  2. Switch to the full-screen card using the card size picker.

  3. Click the All Sessions tab.

  4. Select the session of interest, then click (Open Card).

  5. Locate the medium Network Services|LLDP Session card.

  6. Hover over the card, and change to the large card using the card size picker.

  7. Hover over the card and click to open the LLDP Configuration File Evolution tab.

  8. Select the time of interest on the left; when a change may have impacted the performance. Scroll down if needed.

  9. Choose between the File view and the Diff view (selected option is dark; File by default).

    The File view displays the content of the file for you to review.

    The Diff view displays the changes between this version (on left) and the most recent version (on right) side by side. The changes are highlighted in red and green. In this example, we don’t have any changes to the file, so the same file is shown on both sides, and thus no highlighted lines.

View All LLDP Session Details

You can view attributes of all of the LLDP sessions for the devices participating in a given session with the NetQ UI and the NetQ CLI.

To view all session details:

  1. Open or add the Network Services|All LLDP Sessions card.

  2. Switch to the full-screen card using the card size picker.

  3. Click the All Sessions tab.

  4. Select the session of interest, then click (Open Card).

  5. Locate the medium Network Services|LLDP Session card.

  6. Hover over the card, and change to the full-screen card using the card size picker. The All LLDP Sessions tab is displayed by default.

  1. To return to your workbench, click in the top right of the card.

Run the netq show lldp command.

This example shows all LLDP sessions in the last 24 hours.
