C8200 max uplinks

[mrslyfox686]

Hello,

Checking C8200-1N-4T and C8300-1N-4T as a candidate to substitute the current silver peak solution I have in place. 
I can’t find information in the documentation about what is the maximum number of uplinks (RG45) that can be connected to the router for the needs of SD-WAN? And maybe someone know what kind of limitations C8200-1N-4T has in comparison to C8300-1N-4T except throughput.

Hi,

C8200-1N-4T has 4 port RJ45 and can have L3 interface module (NIM) C-NIM-2T which supports 2 port 100/1000Mbps dual mode (SFP or RJ45).

C8300-1N-4T where did you see that model? Datasheet does not contain such model

Hello @Kanan Huseynli 
my mistake, C8300-1N1S-4T2X I consider as alternative to C8200-1N-4T 
two devices per location (for redundancy), 3 x DIA uplinks 300Mb/s each

[Kanan Huseynli]

So, 8200 model has 4 built-in copper ports + 1 NIM support. 8300 has 4built-in copper + 2x10G SFP ports + 1 NIM support.

You will have 900Mbps WAN bandwidth, however 8200-1N-4T supports :

SD-WAN IPsec throughput (1400 bytes)

Up to 1 Gbps

SD-WAN IPsec throughput (IMIX*)

900 Mbps

I'd go with 8300 option.

C8300 better decision.

C8300-1N1S-6T - depends on traffic it can Up to 2Gbps sdwan (Throughput with IQDF^** (1400Bytes)) or 1.7Gbps SD-WAN IPsec (Throughput with IQDF^** (IMIX^{* average packet size of 352 Bytes packet size}))

C8300-1N1S-4T2X - depends on traffic it can Up to 17Gbps (Throughput with IQDF^** (1400Bytes)) or 5.5Gbps SD-WAN IPsec (Throughput with IQDF^** (IMIX^{* average packet size of 352 Bytes packet size}))

you need more uplink to make it bundle them ? or they going to different providers ?

[dijix1990 · Accepted solution]

С8200 has two L3 ports as copper (RJ45) and two L3 ports for sfp so you can use sfp glc-te for sfp ports. If you need more than 4 ports you can buy nim card with two L3 ports - C-NIM-2T it has two ports RJ45 or SFP or you can buy C-NIM-8T it has 8-port Layer 2/3 GE Switch Network Interface Module or you can buy NIM-ES2-8 and use it for increase physical ports (just connect one of ports from NIM-ES2-8 for connecting to onboarding ports as switch)

BTW. We use some C8200 with NIM-ES2-8 and some with C-NIM-2T/C-NIM-8T. For every kind of sets we use only 5 ports two for lan and 3 for ISP's (two internet and one mpls)

[dijix1990]

C8300-1N1S-6T has four L3 ports as copper (RJ45) and two L3 ports for sfp (6 onboarding ports) and C8300-1N1S-6T can use with C-NIM-8T it has 8-port Layer 2/3 GE Switch Network Interface Module if you need more L3 ports you can buy for C8300-1N1S-6T extra C-NIM-8T (Two) with adapter C-SM-NIM-ADPT.

So maximum L3 ports (with extra C8300-1N1S-6T) for C8300-1N1S-6T = 30

BTW, I haven't dug into the datasheets for the 8200s/8300s, but in the past, on other routers, L3 add-in ports sometimes had additional feature or performance port limitations compared to the built-in L3 ports.  Further, sometimes the router didn't have the forwarding capacity to support all the possible L3 ports, concurrently, at wire-speed/line-rate.
