Advanced queuing (CBWFQ, LLQ) and traffic shaping for bandwidth management.
The Cisco 3725 is a modular multiservice access router, widely adopted in enterprise branch offices and by network professionals in lab environments. Its modular design supports network modules (NMs) for voice, security, switching, and ATM. The 3725 is commonly used for CCNP, CCIE, and other professional-level studies. It comes with default RAM and flash of 128 MB and 32 MB, but memory upgrades are necessary for running larger IOS images like 12.4(25d).
