You are configuring Ethernet Ring Protection Switching (ERPS) on an ArubaOS-CX switch. Is this a guideline for configuring timers?

Suggested answer: A

Explanation:

ERPS is a feature of ArubaOS-CX that prevents loops at layer 2 on ring networks1. ERPS uses a protocol called Ring Auto Protection Switching (RAPS) to detect link failures and perform fast traffic switchover1. ERPS has two timers that control the protection switching mechanism: guard timer and hold off timer1. The guard timer prevents false switching caused by delayed or lost RAPS PDUs1. The guard interval is set in units of 10 ms and should exceed the maximum expected delay for forwarding a frame around the complete ring1. This ensures that all switches on the ring receive the RAPS PDUs before the guard timer expires1. Therefore, this is a guideline for configuring timers for ERPS, and the correct answer is yes. For more information on ERPS and timers, refer to the Aruba Data Center Network Specialist (ADCNS) certification datasheet2 and the ERPS Guide for your switch model1.
