Question 12

What deployment scenarios suit Cisco 550X Series?

Accepted Answer

Cisco 550X is ideal for small to medium enterprises, branch offices and campus edge deployments requiring high-performance stacking, PoE/PoE+ and advanced security.

Question 13

What is the switching capacity and performance of Cisco 550X?

Accepted Answer

Cisco 550X delivers up to 176 Gbps switching capacity per switch and 130.95 Mpps forwarding rate, ensuring low latency and wire-speed performance for converged networks.

Question 14

Are there energy efficiency features in Cisco 550X?

Accepted Answer

Cisco 550X supports Energy Efficient Ethernet (IEEE 802.3az), fan speed optimization and PoE power scheduling to reduce power consumption during low-traffic periods.

Question 15

Do I need extra licensing for advanced features?

Accepted Answer

All essential L2/L3, QoS, security and stacking features are included in the base Cisco IOS image. No additional licenses are required for standard deployment.

Question 16

How does Cisco 550X differ from the 350X Series?

Accepted Answer

Compared to 350X, the 550X offers higher stacking bandwidth, greater forwarding capacity, improved PoE budget, more uplink options and advanced security and routing capabilities.
