Product Number Description
C3850-NM-4-1G 4 Gigabit Ethernet SFP
C3850-NM-2-10G 4 Gigabit Ethernet SFP / 2 10 Gigabit Ethernet SFP+
C3850-NM-4-10G 4 Gigabit Ethernet SFP / 4 10 Gigabit Ethernet SFP+
Remark: 4x10 Gigabit uplinks are only possible with the 48-port version, the 24-port
version only supports 2x10GbE uplinks.
Recommendations
The models Cisco Catalyst 2960X-24TS and 2960X-48TS can be used for small setups
where no inter-VLAN routing is needed and no 10G uplinks.
The models Cisco Catalyst 2960X-24TD and 2960X-48TD can be used for small setups
where 10G uplinks are required, but no inter-VLAN routing is needed.
On larger setups, both GbE ports of the XT4K servers or/and several ports on the SANs
are often used to increase the bandwidth or to allow redundancy. Since both GbE ports of
XT4K server cannot be used on the same sub-network, virtual LANs need to be created.
To allow the transfer of packets between the virtual LANs, layer 3 switches are required.
You need to select a layer 3 switch that is able to route jumbo frames. The Cisco Catalyst
3850X series does support jumbo frames, allows traffic to be routed between different
VLANs and provides stacking capabilities.
