4[blank_start]port security[blank_end] is a security countermeasure is effective for preventing CAM table overflow attacks.
- Aport security
5The STP [blank_start]loop[blank_end] Guard feature provides protection against Layer 2 loops by recognizing unidirectional links and moving them to the blocking state.
- Aloop
