XG-7100 efficiency low?
-
I try to use multiple pipes with speed of 1gig. It works fine on a single port and single 1gig but once I use more eg. additional gig to another port and test using multiple laptop off multiple ports(each port gets different gateway/pipe) I can go over 1gig total, why? Isnt this model suppose to go close to 5gig total on all ports?
Enable PowerD to maximum

Hi,
Possible issue : check out this question https://forum.netgate.com/topic/144915/what-is-wrong-with-my-pfsense-limiters and you'll get the picture ;)
-
The thing is, I don't use limiters or shapers on those interfaces I test
-
It would be really bad if that unit is able to do only 1gig as oppose to min 2.5gig x2.
I bought few units XG-7100 and tons of SG-4860 just to discover this now? -
It's my understanding that the backplane of the switch supports up to 5Gbps (2x 2.5Gbps) so with large amounts of traffic on the switch ports, it doesn't get overloaded. I'm also assuming that if one of the fiber ports is used as a WAN port, the high-speed backplane on the switch itself is easily able to talk to the fiber ports at full speed.
So, I believe the only way you are going to get higher than 1Gbps on a single port on the XG-7100 is to use the SFP+ ports. You could also add an additional card, with high speed fiber ports, into the expansion slot. I would consult Netgate, however, on what the best approach is to doing it this way.
The SG-4860, by the way, will never support faster than 1Gbps on any port.

I am not talking about speed from one port but 2 diffrenet LANs and 2 diffrenet WANs if you read my first post you will get picture.

Um no, your first post wasn't that clear.
You now say 2 different LANs and 2 different WANs. What ports on the XG-7100 are you using for the 2 LANs and what ports for the 2 WANs? To get anything faster than 1Gbps, I believe you have to use the SFP+ ports. If you're not, and you are simply using the built-in switch ports, you only get 1Gbps to each port. Even if you bond (LAGG) ports together, you don't get any faster than 1Gbps. You simply get redundancy, not additional speeds.

Let me give you more clarification. I don't use any SFP and dont need to test anything more that a single gig off single port.
I use only all standard copper ports
- port1 - wan 1 - isp1 1gbs
- port2 - wan 2 - isp2 1gbs
- port3 - lan1 with a gateway pointing to ISP1
- port4 - lan2 with a gateway pointing to ISP2
laptop 1 connected to lan1 port3
laptop 2 connected to lan2 port4Now I do speed test on two laptops at the same time trying to see what is the throughput capability of xg7100. single laptop of single port is gig, fine, but once you connect the second trying to engage second pipe I am getting not more that gig total looking at two screens of 2 laptops.
-
So your laptops are only see 500mbps vs 1g when you run both..
But when you run 1 you see 1g, you run 2 you see 1g, run both at same time you only see 500mbps each is what your saying.
You sure your routing them correctly via your 2 isps?
-
Yep LAN-1 goes via ISP1 , LAN-2 goest via ISP2 there is not much room for mistake here when choosing the gateway, the result is less or more as you said, laptops are fighting for what looks like total 1gig combined on both sometimes 300 vs 700 sometimes 500 vs 500. Which is really weird and inefficient. PowerD set to max, No heavy NAT, no limiters on tested networks. I do have squid but it is disabled.
-
And these are 2 completely different isp.. Or you connected 2 different devices to the same?
What your hinting at is the routing can only do 1 gig total... Or that the backplain of the switch can only move 1 gig total? Which makes no sense.
You don't have ports 3 and 4 bridged do you?
So lan 1 is like 192.168.1/24, lan 2 is is 192.168.2/24 for example
And you have 2 different isp giving you 2 different public IPs completely different from each other.
So you validated via states that the traffic is actually going out 2 different wans?
-
You have the switch internal interfaces in the default load-balance lagg mode?

Correct 2 completely different ISPs. Correct sth is wrong indicating total throughput problem over gig. No bridging. Correct WANs independent separate subnets, LANs also on separate subnets tested directly off untagged ports on xg7100. Before I did test I made sure that my public facing IP is different on each connection.
@stephenw10
Each tested vlan on lan and wan side is working with default lagg0 -

And you validated that your routing is working as you assume.. Via checking the state tables and traffic flow over both wan side interfaces..
Something is off that is for sure - the thing is way more capable of just 1 gig ;)
Now that @stephenw10 sure can get to the bottom of the issue.. I don't have a XG7100 to play with :( or would be happy to duplicate your testing...
-
I did not checked state tables, only did "what is my public IP" check in the browser.
I have opened ticket with support, sent them status dump for my unit. Waiting for the issue to be potentially replicated, let's see they said it may be days. -
Support never shares anything about any specific issues that get moved to support tickets, even when the thread was started in the forum..
So hope you will share what the issue is, when figure it out. Best I could do would be to duplicate the setup you are using for testing with my sg4860.. But that wouldn't be much help, since doesn't have any switch ports.
-
Will share info whenever they come with some answer.
-
Great.. Got to be something stupid ;) I don't think it will be "days" either..
-
Is your problem fixed?

I had heard a snip from Chris that they were about to discuss with the ticket opener.. But that is all I got out of him ;) Hope the OP comes back and let us know some info about this myself.
