# sk182065 - The output "lldpneighbors" does not contain all the expected information of LLDP Neighbors

| Property | Value |

| Solution ID | sk182065 |
| Date Created | 2024-03-28 |
| Last Modified | 2026-02-18 |
| Technical Level | General |
| Products | Security Gateway |
| Versions | R82, R81.20, R81.10 (EOS), R81 (EOS) |

## Symptoms

- * The Security Gateway does not display all the LLDP (Link Layer Discovery Protocol) neighbors, even though LLDP is enabled on multiple interfaces for those neighbors.  

* The output of the command **lldpneighbors** is truncated and does not contain all the expected information of LLDP Neighbors.

## Cause

The allocated buffer size is too small to display the complete list of LLDP neighbors.  

<br />

## Solution

The buffer size for the "*lldpneighbors* " command is now increased to 8192 bytes, effective starting from:  
**[Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/R81.20/R81.20-List-of-all-Resolved-Issues.htm) - starting from Take 8**   
**[Jumbo Hotfix Accumulator for R81.10](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.10/R81.10/R81.10-List-of-all-Resolved-Issues.htm) - starting from Take 95**   
**[Jumbo Hotfix Accumulator for R81](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81/R81.00/R81.00-List-of-all-Resolved-Issues.htm) - starting from Take 82**   

**If the buffer size is insufficient to display all LLDP neighbors** , kindly please [Contact Check Point Support](https://www.checkpoint.com/support-services/contact-support/) to get a Hotfix for this issue.

<br />

The issue where the LLDP Clish "*lldpneighbors"* command may have a **corrupted output** in case of extensive data, was resolved.  
The fix is included in:

* [Jumbo Hotfix Accumulator for R82](https://sc1.checkpoint.com/documents/Jumbo_HFA/R82/Default.htm) starting from Take 73
* [Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) starting from Take 122
* [Jumbo Hotfix Accumulator for R81.10](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.10/Default.htm) starting from Take 183

If you choose not to upgrade, Check Point can supply a **Hotfix** . [Contact Check Point Support](https://www.checkpoint.com/support-services/.contact-support/) to get a Hotfix for this issue.  
A Support Engineer will make sure the Hotfix is compatible with your environment before providing the Hotfix.  
For faster resolution and verification, please collect [CPinfo files](http://supportcontent.checkpoint.com/solutions?id=sk92739) from the Security Management Server and Security Gateways involved in the case.
