Using the WS-C3850-12XS-S and C3850-NM-8-10G to Expand the Port Density of a Catalyst 3850 Switch

June 19, 2023

The Catalyst 3850 series switches are a popular choice for enterprise networks. They offer a wide range of features and capabilities, including support for 10 Gigabit Ethernet. However, the base models of the Catalyst 3850 switches have a limited number of 10 Gigabit Ethernet ports. This can be a problem for networks that need to connect to high-speed devices, such as servers and storage arrays.

The WS-C3850-12XS-S and C3850-NM-8-10G are two modules that can be used to expand the port density of a Catalyst 3850 switch. The WS-C3850-12XS-S is a 12-port SFP+ network module that supports 10 Gigabit Ethernet. The C3850-NM-8-10G is an 8-port 10 Gigabit Ethernet module that can be used to add 10 Gigabit Ethernet ports to a Catalyst 3850 switch that does not have a native 10 Gigabit Ethernet uplink port.

To use the WS-C3850-12XS-S or C3850-NM-8-10G, you will need to install it in a Catalyst 3850 switch. The modules can be installed in any available network module slot. Once the module is installed, you will need to configure it using the Cisco Catalyst 3850 switch management interface.

To configure the WS-C3850-12XS-S or C3850-NM-8-10G, you will need to create a new network interface for each port on the module. You can then assign an IP address and subnet mask to each network interface. You can also configure other features for the network interfaces, such as VLAN membership and QoS settings.

The WS-C3850-12XS-S and C3850-NM-8-10G are a great way to expand the port density of a Catalyst 3850 switch. By using these modules, you can add more 10 Gigabit Ethernet ports to your network, which can help to improve performance and reduce congestion.

Here are some additional benefits of using the WS-C3850-12XS-S and C3850-NM-8-10G:

Increased bandwidth: The WS-C3850-12XS-S and C3850-NM-8-10G can provide up to 10 Gigabit Ethernet bandwidth per port, which can be used to improve the performance of applications that require high bandwidth, such as video streaming and file sharing.

Reduced congestion: By adding more 10 Gigabit Ethernet ports to your network, you can help to reduce congestion on your existing network links. This can improve performance for all devices on your network.

Increased flexibility: The WS-C3850-12XS-S and C3850-NM-8-10G can be used to connect a wide variety of devices to your network, including servers, storage arrays, and high-end workstations. This can give you more flexibility in designing your network.

In conclusion.

If you are looking for a way to expand the port density of your Catalyst 3850 switch, the WS-C3850-12XS-S and C3850-NM-8-10G are a great option. These modules can provide you with the bandwidth, performance, and flexibility you need to meet the demands of your network.
