The RUCKUS ICX switch must have Bridge Protocol Data Unit (BPDU) Guard enabled on all user-facing or untrusted access switch ports.

An example is a firewall that blocks all traffic rather than allowing all traffic when a firewall component fails (e.g., fail closed and do not forward traffic). This prevents an attacker from forcing a failure of the system to obtain access. Abort refers to stopping a program or function before it has finished naturally. The term abort refers to both requested and unexpected terminations.

Review switch port configuration on all untrusted access ports.

If untrusted access switch ports are not configured for BPDU Guard, this is a finding.

Configure switch BPDU Guard enabled:

1. Global Config mode: Router# configure terminal

2. Interface level mode: Router(config)# interface ethernet 1/1/1

3. Implement stp-bpdu-guard: Router(config-if-e1000-1/1/1)# stp-bpdu-guard

4. Save: Router#write memory
