LLDP data formatting issues when querying using SNMP

Product: Security Gateways
Version: R81.10 (EOS), R81.20, R82
OS: Gaia
Last Modified: 2026-05-26

Symptoms

• LLDP output using SNMP shows interface names as hexadecimal values instead of strings, especially for certain neighbor interfaces (for example, "Eth101/1/10" is sent as hex, while "Ethernet1/12" is sent as a string).
• The Chassis ID (MA field) for MAC address is also not in the expected format.
• All data is returned on a single line instead of multiple lines.
• The issue is observed consistently when querying using SNMP, but not when running the script directly on the CLI.

Cause

Incorrect MAC address extraction. The code fails to correctly read MAC address bytes from network packets.

Solution

This problem was fixed. The fix is included in:

• Jumbo Hotfix Accumulator for R82 starting from Take 103
• Jumbo Hotfix Accumulator for R81.20 starting from Take 122
• Jumbo Hotfix Accumulator for R81.10 starting from Take 183

If you choose not to upgrade, Check Point can supply a Hotfix. Contact Check Point 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 from the Security Management Server and Security Gateways involved in the case.
