With the development of the times, the enterprise campus network has become an important part of the communication infrastructure.

The Cisco Catalyst 4500-x series switch is a new solution for converged switches on the campus LAN, it provides a 10G uplink in a simple and cost-effective manner.

In addition, it also provides scalability, simple network virtualization Settings and three-in-one network services for the network space of the campus that meeting the needs of future network development.

Today, we would like to introduce the 10G SFP+ optical module and solution applied to Cisco Catalyst 4500-x series switches:

Optical module solution

Not all SFP or SFP+ optical modules on the network port on the front panel of the Cisco Catalyst 4500-x series switch can be used on the Cisco Catalyst 4500-x series switch. In addition, there are some limitations when using SFP-10G-ZR SFP+ optical modules on this switch:

1. Regardless of the direction of cooling airflow used by the Cisco Catalyst 4500-X Series Switches, SFP-10G-ZR SFP+ optical modules can be used in the 1-8th uplink module on the switch.

2. When the Cisco Catalyst 4500-X Series switches use front-to-back cooling airflow, SFP-10G-ZR SFP+ optical modules can be used in ports 1-32th or 1-16th on the switch. In contrast, the SFP-10G-ZR SFP+ optical module cannot be used when using a cooling airflow from back to front.

Virtual switching system for Cisco Catalyst 4500-X series switches

The most important of the Cisco Catalyst 4500-X Series Switch is its support for virtual switching systems. A virtual switching system combines two switches into one logical switch. Externally, there is only one switch. Virtual switching systems simplify the network by reducing the number of network devices and simplifying the management of redundant devices and links.

Any two Cisco Catalyst 4500-x series switches can be combined into one logical switch, eventually providing a maximum of 80 SFP+/SFP ports, and the bandwidth capacity of the entire system is expanded to 1.6 Tbps.

This article not only introduces the SFP+ optical modules and solutions for Cisco 4500-X series switches, but also explains the virtual switching system for this series of switches.
