What are the supported uplink modules in the Cisco Catalyst 3850?

The Cisco Catalyst 3850 supports the following uplink modules: ● 4 x 1GE network module ● 2 x 1/10GE network module ● 4 x 1/10GE network module (can be used for the 48-port RJ-45 models and for the 12-port (or higher) 10‑gigabit-capable models) ● 8 x 10GE network module (can be used on the 24-port and 48-port multigigabit switch and also on the 24‑port 10G SFP+ switch) ● 2 x 40GE network module (can be used on the 24-port and 48-port multigigabit switch and also on the 24‑port 10G SFP+ switch)

Are the uplinks between the Cisco Catalyst 3850 and the 3750-X interchangeable?

No, the uplink modules from the 3750-X are not compatible with the Cisco Catalyst 3850.

Can the Cisco Catalyst 3850 act as a wired switch?

The Cisco Catalyst 3850 switch can act as a wired switch as well as a converged wired wireless switch.

Does the Cisco Catalyst 3850 10G SFP+ 48-port switch support uplink modules?

No. It has 4 fixed 40G QSFP ports for uplinks. This is not field-replaceable.

What about service modules for the Cisco Catalyst 3850?

There are no service modules for the Cisco Catalyst 3850. Features supported through the service module in the 3750-X (including Flexible NetFlow and MACsec *) are natively supported by the Cisco Catalyst 3850.

Is there an onboard web GUI on the Cisco Catalyst 3850?

Yes. Onboard web GUI requires Cisco IOS XE Release 3.2.2SE or later.

What management ports are available on the Cisco Catalyst 3850?

The Cisco Catalyst 3850 comes with a 10/100 Ethernet dedicated management port on the backside of the switch right above the console port. This port is in separate VRF called “Mgmt-vrf.” This is to segment the management traffic from the global routing table of the switch.

What is the maximum number of VRFs (Virtual routing and forwarding) that can be configured on a Cisco Catalyst 3850?

Maximum number of VRFs that can be configured on a Cisco Catalyst 3850 is 27.

Can both console ports be used simultaneously?

No. When the USB console is used, the RJ-45 console receives the output of the USB console as well. This design allows the administrator to see when the USB console port is in use. This capability is useful for remote administrators.

Does the switch support auto-baud on the console port?


What type of airflow do the Cisco Catalyst 3850 switches support?

The airflow on the Cisco Catalyst 3850 is “front and sides” to back airflow except for the 48-port 10G SFP+ switch. The 48-port 10G SFP+ switch has support for front-to-back and back-to-front airflow.
