I have found recently that Cisco 1905 router is having a throughput of only 10 Mb. But the router is having 2 Gig ports!.My understanding is that throughput is the data packetforwarding done by a router at a time.
What is actually mean by throughput of a router. How the router can handle 1 Gb of data from interfaces at a time?
I'm trying to identify a Cisco router that will give 300+Mbps through a 1Gb WAN port. I think the 1921 can get up to around 300Mbps with the on board RJ45 ports, but are there any other/better suitable models?
There's no need for any other particular functionality or feature set, the routers aren't doing anything fancy or unusual - it's the achieved throughput that's important.
I am facing a problem on a 2811 router. The CPU is remaining around 60% and the router throughput is reaching at most 18 MB while according to the data sheet the 2811 maximum throughput is 61MB. I have checked the output interpreter in order to try and figure out the cause of the high CPU and to determine if it is affecting throughput but there are not processes consuming more than 10%. I have attached the show tech-support and the show process cpu history outputs.

The SAN is configured in passive LACP and the switch is in active LACP. Actually it does not matter if we do LACP or just MODE ON, still same result: ~1GBit/s throughtput in either direction. Like already mentioned, 2 or 4 ports in the etherchannel make no difference, or the configuration of the etherchannel.
I will post some config data below, but here is the question: Why can't we see traffic beyond 1GBit/s? Source and destination are capable of doing much more than that (vmware esxi RAID 5 of 1TB SATA; SAN 16 x 1TB NL-SAS). If we look with CNA, we can see that the traffic is balanced equally over the etherchannel ports. With or without QOS or flowcontrol, no difference. This whole traffic happenes on this switch.

View 15 Replies View RelatedWhen transferring traffic between two VLANs my throughput rate seems to drop to about 1.5 - 3.0 megabits / second.
My setup is like this...
Two Nexus 5020 switches. (switch01 and switch02)
Two Nexus 2232PP fabric extender switches. (switch03 and switch04)
Two Dell R815s with Chelsio and Intel NICs. (host1 and host2)
The servers run Xenserver 6.0, but as part of testing with this I've tried installing RedHat 6.2, VMware ESX 5.0 (vsphere 5).
The issue occurs when using trunking and transferring data from one VLAN to another. Example...
VM1 is in VLAN401 with an IP address of 10.100.40.40. The VM is on Host1. VM2 is in VLAN402 with an IP address of 10.100.50.50. The VM is on Host2.
I've been using a network throughput tool called iPerf to test and I find that I can only get a throughput rate of about 3.0megabits.
If I switch VM2 to be in VLAN401 with an IP address of 10.100.40.41 I get a throughput rate of about 6.7gigabits/sec.
In the above scenario, I'm using a Layer3 interface on the Nexus 5020, but in production we use a Vyatta virtual firewall.
I worked with Citrix for about 3 months and that was a dead end.
I realize this is just a small business switch, basically a rebranded Linksys, but why I'm only getting 200Mbits/s
- 48 port - 10/100/1000 , set to standalone mode
- 3 separate PCs on this switch , all are fast machines with Core 2 duo / plenty of RAM etc...
- all 3 auto-sense 1Gbps connection
I use iperf tool for bandwidth testing and no matter which PC I pick as server, which as client I get about 150 to 250Mbits/s
I am not looking for full 1000 here, but 200 seems rather sad....
- jumbo frames seem to make no difference
- I am using TCP test in iperf , standard no extra flags , 10 seconds, 20 seconds or even 30 seconds all come out the same.
- wiring is shady as some of it is just Cat5 , but when going from one laptop on the switch to another with brand new Cat6 cables I STILL only got 200.
I am currently using catalyst 4506 L3 switch and 2950 L2 switches for pc's which are EOL. I am replacing L3 with 3750X, two switches in a stack. L2 is 2960S all with gbps ports. I have to have a baseline (performance comparison with the current setup and new setup) and I am using the following methods
1. Iperf throughput comparison among local vlans
2. Iperf throughput comparison with remote data centers servers.
3. Ping/ftp upload/download comparison with remote DC's. FTP file is around 3GB.
Today I have tested the above with the new setup and compared it with the old setup. For the tasks 1 & 3 I found better performance with the new setup. However the task 2 did not show any performance increase infact the throughput was much lower comparing to the old setup.
I see the throughput of a ISR is 296.96 Mbps how would this compare to a 3560 if the figure is 38.7Mpps?
What would the throughput of a 3560 be in Mbps?

As I understood, the only L3 catalyst that is able to perform NAT is a 6500? Is that correct? If the above is correct, it seems I can only replace the setup by using a router/ASA with a L2 switch. A router with high throughput (+/- 300Mbps) is hard to find, especially as NAT will require CPU resources...
So, my best (affordable price) solution is getting an ASA5520 (450Mbps FW throughput) and a L2 switch?

View 1 Replies View RelatedWe are experiencing output drops on our 3750G-12S (IOS 12.2.55).
I have monitored throughput with MRTG, but it doesn't seem that high compared to that the 3750G is supposed to handle 17.8 Mpps.
The 3750G's are stacked, running ospf, qos, multicast (IPTV) and etherchannel.Is the maximum throughput reduced by stacking or any of the other features?
I don't know if one can estimate what the maximum throughput is per ASIC or per port, but on one of the ASICs that is having drops the peak unicast load is 1.3 Mpps and multicast Mpps is 0.9 Mpps. Total ~2.2 Mpps.
This doesn't seem high at all and I don't understand why the drops are appearing. What I can do to find out the reason for these drops?
How i can view the capacity throughput (backplane) of core switches (6509)? How i know much is in use?

you can configure a cisco 1905 router with vpn ipsec site-to-site in an aggressive mode? If so, any link to what I do? The VPN works well, but on site A, I had to configure a crypto map associating the IP address for site B (wich is dynamic), so if the connection on site B broken, I will have to configure another crypto map.
The scenario is:
Site A - ASA 5510 configured as a VPN concentrator and firewall for enterprise.
Site B - Cisco 1905 connected to Internet through a ADSL through a dynamic IP address and starting connection to Site A, bellow is the configuration:
crypto isakmp policy 10

I have been trying to find out what the maximum Wan to Lan thruput is for the Linksys Cisco BEFSR 41 Etherfast router..
Have both the version 3 and 4 models and want to deploy them into both 6mb and 12mb DSL networks.. From what I have found the version 1 and 2 have 10mb wan ports and the version 3 and 4 have 10/100mb ports.. There seems to be hardware upgrades as well with the CPU and memory speeds but what they are I do not know for sure.. Found someone stating that they went from a 50mhz CPU to a 166mhz CPU to a possible 220mhz CPU...
I have a 3640a, 3550 and airopoint 350 I use for my home internet connection. I know it's old equipment, but it's all I could afford at the time. Directly plugged into my modem I get about 10 mb/s, plugged into a switch port no greater than 6, and about 5-6 when connected to wireless which is understandable because it's only wireless B. I'm going to downgrade my connection for the time being as I'm paying for excess bandwidth that I'm unable to use, but any more recent, affordable cisco routers that can handle a high speed cable connection? What kind of throughput does the 3550 get? Cisco states a throughput of approximately 45-60mb/s for the 3640a.

What is the WAN to LAN Throughput of RV042 router with QoS and SPI enable?
Will the RV042 router able to support a 60Mbps down 3Mbps up Internet connection with QoS enable and SPI enable without slowing down the connection?
I am looking to find the correct router for a 50 Mbps Ethernet connectin that is for Internet traffic. It will need to support 50 Mbps throughput, along with routing protocols for BGP, and maybe NAT/ACL's. It most likely will be a used router, in the 2800 series. I'm thinking a 2821 would work, but need to make sure before I pass it on to the customer. They currently have a 3660 they were thinking of using, but I think it would be too weak, and probably only pas 30Mbps at the most before it chokes. They are a mini ISP with their own ASN, Tier 3.
View 3 Replies View RelatedI recently bought a WRT160NL router. I have a 10/10 Mbps internet connection, but when I am connected via the router it only gives me ~2.5/1 Mbps speeds. Connecting my computer directly to the "wall" results in 10/10 Mbps speeds. I have tried connecting to the router both wireless and by wire, it makes no difference. The internal wired and wireless speeds are fine, as I have copied files over the internal switch and via the wireless network at relatively high speeds. I have not fiddled with any connection settings except creating a few permanent DHCP leases.
