Description
The STP loop Detect feature provides additional protection against STP loops. An STP loop is created when an STP blocking port in a redundant topology erroneously transitions to the forwarding state. In its operation, STP relies on continuous reception and transmission of BPDUs based on the port role. The designated port transmits BPDUs, and the nondesignated port receives BPDUs. When one of the ports in a physically redundant topology no longer receives BPDUs, the STP conceives that the topology is loop-free. Eventually, the blocking port from the alternate or backup port becomes a designated port and moves to a forwarding state. This situation creates a loop. The loop detect feature makes additional checks. If BPDUs are not received on a nondesignated port and loop detect is enabled, that port is moved into the STP loop-inconsistent blocking state.

Who does this work

12 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-273679r1110982_chk)

Review the switch configuration to verify that STP Loop Detect is enabled. Verify: ICX7150-24P Switch#show run ! vlan 10 by port tagged ethernet 1/1/1 to 1/1/2 ethernet 1/1/5 ethernet 1/1/7 ethernet 1/1/9 ethernet 1/1/11 spanning-tree loop-detection ! If STP Loop Detect is not configured globally or on nondesignated STP ports, this is a finding.

Fix Text (F-77675r1110739_fix)

Configure the switch to have STP Loop Detect enabled globally or at a minimum on all nondesignated STP switch ports. 1. Configure loop detect.
