Need suggestion on WS-C3650-24TD-S uplink port

[Tarun Vyas]

We are having EOL WS-C3560G-24TS-S switch and looking suggestion to purchase a new device. I have suggested a WS-C3650-24TD-S latest device.

WS-C3650-24TD-S

Fixed Uplinks : 2 x 10 Gigabit Ethernet with SFP+ and 2 x 1 Gigabit Ethernet with SFP

Note : The SFP+ interface supports both 10 Gigabit Ethernet and Gigabit Ethernet ports.

I have big confusion on its fixed uplinks description.

1) As it has given Gigabit Ethernet port.

Confusion : Can I use only ethernet module (GLC-T) or I can use fiber SFP module (1000BaseSX SFP) also on all of four uplinks.

2) Can I use all four port with 1 Gig module

3) When I am using 10 Gig uplinks in SFP+ port at same time can I use remaining 2 port as 1 Gig uplink.

I have referred below link from cisco to understand the things but still I am not clear.

See table-1 in this link:

https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-3650-series-switches/datasheet-c78-729449.html

It depends which model you get.  For example:

If you get "WS-C3650-24TS" this comes with only 4 1Gig and no 10Gig

If you get "WS-C3650-24TD" this comes with 2 10Gig and 2 1Gig

if you get "WS-C3650-48TQ" this comes with 4 10Gig or 4 1Gig

for 1Gig you use SFP and for 10Gig you use SFP+

GLC-T is only compatible with 1Gig ports.

BTW, the 3650 series switches are good switches.

1) You can mix GLC-T, GLC-SX-MMD, GLC-SX-MM, GLC-LH-SMD, GLC-LH-SM

2) Yes

3) According to Table 1 and Table 2 on page Cisco Catalyst 3650 Series Switches Data Sheet can be used 2 x 10 Gigabit Ethernet with SFP+ and 2 x 1 Gigabit Ethernet with SFP at the same time.

The 9000 series switches replaced the 3650 series.  You should probably be looking at a 9300:

Yes that switch is fine for 4x1GB see chart below , just requires sfp no extra commands
