Description

The Catalyst 3850 12-port Gigabit SFP switch is a stackable 1 RU Layer 3 access and aggregation switch built for fibre-based enterprise campus and branch deployments. It suits sites where fibre links or EMI-sensitive and secure environments are needed, and it can aggregate smaller access switches in branch locations. As part of the Catalyst 3850 family it also supports converged wired and wireless access, acting as a wireless mobility agent or controller.

This SKU provides 12 x 1 Gigabit Ethernet SFP ports and ships with the IP Base feature set and a 350W AC power supply (PWR-C1-350WAC). It is a non-PoE model. Switching capacity is 68 Gbps with a forwarding rate of 50.5 Mpps, and it supports 32,000 MAC addresses, 24,000 IPv4 routes and 4,000 VLAN IDs. Optional C3850-NM-4-1G or C3850-NM-2-10G network modules add uplink capacity.

It stacks with other Catalyst 3850 switches running the same feature set using StackWise-480 at 480 Gbps, and StackPower allows power sharing between stack members. The second power supply bay supports redundancy with the PWR-C1-715WAC, PWR-C1-1100WAC or PWR-C1-440WDC. The IP Base feature set can be upgraded to IP Services with an RTU licence.

FAQs

Q: Does this switch need a licence?
A: It ships with the IP Base feature set. You can upgrade to IP Services with an RTU licence. Cisco DNA Essentials or Advantage term licences are only needed for SD-Access and DNA features.

Q: Does it provide PoE?
A: No. This is a non-PoE model with a 350W AC power supply, so there is no PoE budget. A second power supply bay supports redundancy.

Q: Which uplink modules does it support?
A: It supports the C3850-NM-4-1G and C3850-NM-2-10G network modules. The C3850-NM-4-10G, C3850-NM-8-10G and C3850-NM-2-40G modules are not supported on this model.

Q: How does it stack with other Catalyst 3850 switches?
A: It stacks over StackWise-480 using STACK-T1-50CM, STACK-T1-1M or STACK-T1-3M cables for 480 Gbps of stack bandwidth. Stack members must run the same feature set. StackPower cables CAB-SPWR-30CM and CAB-SPWR-150CM are used for power sharing.

Q: Which power supplies can be used for redundancy?
A: The second power supply bay accepts the PWR-C1-715WAC, PWR-C1-1100WAC or PWR-C1-440WDC alongside the default PWR-C1-350WAC.
