Cisco Catalyst 3650 Series Switches are stackable
access-layer switches that provide full wired and wireless convergence on a
single platform. The Cisco Catalyst 3650 enables uniform wired-wireless policy
enforcement, application visibility, flexibility, application optimization, and
superior resiliency.
All Cisco Catalyst 3650 Series Switches
have fixed, built-in uplink ports. The table below provides high-level
comparisons of the different available models in the Catalyst 3650 Series
Switch family. You may view all models with:
·
2 x 10 Gigabit
·
4 x Gigabit
·
4 x 10 Gigabit
All models can be purchased with LAN Base, IP Base, or IP
Services software. Customers need to purchase the IP Base or the IP Services
software-enabled models in order to gain wireless function.

Overview
It is possible
to have a combination of a pair of SFP modules (left two) and a pair of SFP+
modules(right two) on the 2 X 10G/4 X 1G uplink type of the Cisco Catalyst
3650. This combination provides up to 22
Gbps of uplink bandwidth.
There are no service modules for the Cisco Catalyst 3650. The
Cisco Catalyst 3650 natively supports the features supported by the service
module in the 3560-X. The Cisco Catalyst 3650 is hardware ready for MACsec, and
software support will be added in a future release. Check release notes for
availability.
The Cisco Catalyst 3650 comes with a 10/100/1000 Ethernet
dedicated management port on the backside of the switch right below the console
port. (See Figure 1.) This port is in a separate VRF called “Mgmt-vrf.” This is
to segment the management traffic from the global routing table of the switch.

Online insertion and removal of the
following are supported:
● Stack member switches in the
stack
● Power supply and fans
● SFP/SFP+ modules
● Stack adapter and cables
Removing,
and connecting to SFP transceiver modules
Hold
the SFP transceiver module on the sides, and insert it into the SPF module slot
on the switch until you feel the connector snap into place.
Note 
They can also be a combination of a pair of SFP modules
slots on the left and a pair of SFP+ module slots on the right. SFP+ module
slots support both SFP and SFP+ modules.
They can also be a combination of a pair of SFP modules
slots on the left and a pair of SFP+ module slots on the right. SFP+ module
slots support both SFP and SFP+ modules.
Connect
an appropriate cable to the module port.
Stacking and High Availability
Cisco Catalyst 3650 is built with the advanced Cisco
StackWise-160. It offers a stacking bandwidth of 160 Gbps nonblocking. The
Cisco Catalyst 3650 requires a stacking kit that includes two data stack
adapters and one stacking cable per switch to enable stacking. New StackWise-160 Modular Adapters and
Stacking Cable
The Cisco Catalyst 3650 Series deployed in StackWise-160 mode
provides the following set of benefits:
● Resilient: The Cisco Catalyst 3650
deployed in StackWise-160 mode enables the Cisco IOS Software SSO
high-availability framework to deliver nonstop communication during fault
conditions.
● Simplified: Single unified system to
manage and operate up to 432 ports. StackWise-160 also simplifies network
design and topologies in converged access.
● Scalable: No performance
compromise. Each Cisco Catalyst 3650 switch deployed in StackWise-160 mode
boosts wiring-closet performance with nonblocking 160-Gbps backplane and 40
Gbps on uplink ports.
Cisco Catalyst 3650 Series
Switches support the following Layer 2 and Layer 3 network protocols:
● Layer 2 protocols: Cisco
Discovery Protocol, Spanning Tree Protocol, VLAN Trunking Protocol (VTP), Link
Aggregation Control Protocol (LACP), Port Aggregation Protocol Plus (PAgP+),
Dynamic Trunking Protocol (DTP), Unidirectional Link Detection Protocol (UDLD)
● Mobility: Access Point management, CAPWAP data tunnel, CAPWAP
mobility tunnel, CAPWAP multicast tunnels
● Layer 3 protocols: EIGRP, OSPF, IS-IS, BGP
● VRF-aware Layer 3 protocols: EIGRP, OSPF, IS-IS, BGP
The total access point count license of a Cisco Catalyst 3650
stack is equal to the sum of all the individual member access point count
licenses, up to a maximum of 25 access points. When new members are added to
the stack, the total access point count license of the stack is automatically
recalculated. When members are removed from the stack, the access point count
license does not decrement until a reload of the stack.
Stack member remove example: In the preceding example,
if switch 4 is removed from the stack, the access point count license stays at
25 access points until the stack is reloaded. After being reloaded, the stack
returns to its original value of 18 access points.
Stack member addition example: A Cisco Catalyst 3650
stack with 3 switches, each with an access point count license of 6 access
points, will have support for a total of 18 access points. When a new Cisco
Catalyst 3650 is added to the stack with an access point count license of 8
access points, the total access points supported by the stack equals 25, since
the total 26 exceeds the stack limit.
