Cisco Catalyst 4500-X Series Switch Family

Cisco Catalyst 4500-X Series provides scalable, fixed-campus aggregation solutions in space-constrained environments. The solution provides flexibility to build desired port density through two versions of base switches along with optional network module, providing line-rate 10GE capability. Both the 32-port and 16-port versions can be configured with optional network modules and offer similar features. The Small Form-Factor Pluggable Plus (SFP+) interface supports both 10 Gigabit Ethernet and 1 Gigabit Ethernet ports, allowing customers to use their investment in 1 Gigabit Ethernet SFP and upgrade to 10 Gigabit Ethernet when business demands change, without having to do a comprehensive upgrade of the existing deployment. The uplink module is hot swappable.

Following are key offering from this product family:

●   32 x 10 Gigabit Ethernet Port switch with optional module slot (Figure 1)

●   16 x 10 Gigabit Ethernet Port switch with optional module slot (Figure 2)

●   8 x 10 Gigabit Ethernet Port uplink module (Figure 3)

In addition, both 32 port and 16 port versions are available with front-to-back and back-to-front airflow. The front‑to‑back airflow switch comes with matching burgundy color fan and power supply handle to indicate warm side. Similarly, back-to-front airflow switch fan and power supply handles are color-coded in blue to indicate cool side. Figure 5 and Figure 6 show rear view of the switch with front-to-back and back-to-back airflow respectively.

Cisco Catalyst 4500-X switch provides redundant hot swappable fans and power supplies (Figure 7) for highest resiliency with no single point of failure.

Best-in-Class Resiliency

The Cisco Catalyst 4500-X Series is designed for excellent nonstop communications with non-interrupted hardware switching. With Cisco IOS XE Software, customers continue to reap the benefits of this best-in-class resiliency in various ways.

In addition to redundant power supplies and fans, the Cisco Catalyst 4500-X is Virtual Switching System (VSS).

Two Cisco Catalyst 4500-X Series Switches of the same model can be pooled together into a VSS. The two switches are connected with 10 Gigabit Ethernet links called Virtual Switch Links (VSLs). Once a VSS is created, it acts as a single virtual Cisco Catalyst switch delivering the following benefits:

Operational Manageability

●   Two Cisco Catalyst 4500-X Series Switches share a single point of management, single gateway IP address, and single routing instance.

●   Eliminates the dependence on First Hop Redundancy Protocols (FHRP) and Spanning Tree Protocol.

Scales to 1.6 Tbps

●   Scales system bandwidth capacity to 1.6 Tbps by activating all available bandwidth across redundant Cisco Catalyst 4500-X Series Switches.

●   Provides up to 80 ports of 10 Gigabit Ethernet per system.

Enhanced Application Visibility with Flexible NetFlow

Cisco IOS Flexible NetFlow is the next generation in flow monitoring technology, allowing optimization of the network infrastructure resources, reducing operation costs, and improving capacity planning and security incident detection with increased flexibility and scalability. The Cisco Catalyst 4500-X Series provides 128K Flexible NetFlow entries. Based on a custom-built ASIC, Cisco Catalyst 4500-X Series delivers unprecedented flexibility and comprehensive flow visibility extending from Layer 2 (MAC, VLAN) to Layer 4 (TCP, UDP flags, and so on).

The flow data collected by Flexible NetFlow can be exported to an external collector for analysis and reporting or tracked by EEM. The Cisco Catalyst 4500-X Series enables powerful on-box and customizable event correlation and policy actions with EEM. This allows the switches to trigger customized event alarms or policy actions when the predefined condition is met. With no external appliance required, customers are able to use existing infrastructure to perform traffic monitoring, making traffic analysis economical even on large IP networks.
