I have a unique requirement.I work in a SAN environment.I have my host connected to a MDS/cisco switch.The host has a HBA(not sure of what speed).The HBA is zoned with a backend storage through a switch.I know the IP of the switch, now can i know the speed of the switch? Also can i koe the speed of the SFP in the switch?
But I am wondering will my overall connection speed decrease if I have multiple devices on? I am just curious as to if I have both say an xbox 360 and my computer on.
I have a 100 Mbps router (which I can't change). But all my computers, media players/streamers, NAS have gigabit Ethernet. Currently, under exclusive use I do approach the 100 Mbps limit (seen a lot of times my laptop transferring files from/to NAS around 14 MBps). But since my devices are capable of handling higher speeds I am thinking to upgrade to a Gigabit switch. That brings me to my question.
If I have 100 MBps router and a Gigabit switch (1k Mac table), what will be max speed between devices connected through the switch?
I am aware anything that goes via the router will hit the roof at 100 Mbps. But will the devices under the switch operate at Gigabit (due to the direct transfer based on mac address)? Or will everything still go through the router who is giving out the IP addresses (the switch having no DHCP) and limit the speed?
I am sutdying at uni and in a few months, I will be moving into a house, with my current flatmates. We will be buying a fibre optic line.Ideally,what I want to do, is split the connections evenly,depending on how many people are online current, rather than having mass downloads of everyone at the same time, when other will only get a small speed while browsing or gaming,or streaming,etc.So, basically, what I want to do is split the connection at anyone time evenly,so if there are 5 people connected and our connection speed is 50MB then each will get 10MB. And if 2 people are connected, then the speed will be 25MB each, and so on.
I am wondering what is the cheapest way of doing this? I am very computer illerate,I know how to use unix systems.I even own my own server, but I'm not so clued up in this area of networking.I believe it's something to do with a switch, and which switches support this? (I've heard it's something to do with full-duplex / half duplex).
- I will probably set up a domain system, where everyone has to login to the main server to access the internet. (I know vaguely how to do that) - is there some software that I can put on the server which will distribute connection speeds automatically.
I am using Intel® 82579V, 1 x Gigabit LAN Controller(s) and CAT 6 cable , however my network utilization is limited to 15%- 35%.I know that practical speeds are lower but is there nay way i can increase this throughput , any maximum throughput experience? On a 1Gbps getting 25% Max utilzization is extremely slow.Am i missing soemthing tat needs tobe corrected .I am working on LAn and ocnnected to a server using HP Procure 2810 series switch.
I am currently connected to my router via a 100 megabit cable (the router port itself is either 100M or 1G, I can't remember). There are no free ports on the router, but I want to connect additional computers to the network. If I get a gigabit switch and connect two of my PCs to it using gigabit cable, can they communicate at gigabit speeds, or will they be limited by the 100M connection back to the router? (In other words, does traffic between two computers on the switch have to be sent through the router, or not?)
I have a Netgear DG470N gigabit modem and I am streaming 1080P films from a 2TB networked hard drive onto a LG 42inch Smart TV viat wired ethernet. Sometimes the films crash and the TV cannot reopen the network folder with the film in until a reset is done on the modem. Is there a high speed gigabit switch that I can use to improve this or should I get some media controlling software?
I am assuming, that the slowest component on a network determines the connect speed? I am having a small network with 4 pcs and 2 of them show 1GB connect speed while the other 2 show 100MB. What would cause 2 units to run at the 100MB speed on a Gigabyte-Switch and Router?
We have an old 3508XL switch. We are trying to connect a new 2960 to it but we purchased the incorrect SFP insert and that speed can only do 100mb. We are getting link flaps and we suspect that it's a speed issue between the two. However, I cannot find how to set the speed on the old OS of the 3508 switch.
Below is a show version of the 3508 switch.

Our client having one c3750 with ipbase license switch.They are connected server and end switches to that switch.Our customer want to increase the speed to accessing the server at that time I am told to use etherchannel.Customer happy about this and implement the etherchannel configuration.Now i need to configure etherchannel upto 4 physical link.server are connected on port no Ge1/0/10,they want to bind four phical link GE1/0/10-13.how to configure etherchannel in this switch?
I just "upgraded" from an E1000 to an E1200 wireless router. I had good performance with the E1000, and I only upgraded to the E1200 because it was on sale.My only complaint with the E1200 is the slower download speed on my desktop PC that is connected directly to the router. My normal download speed on the desktop PC was 25 Mbps with the E1000 model. After I disabled the WMM on the E1200 as others suggested, the download speed on the desktop machine immediately increased from 5 Mbps up to 15 Mbps. Any other suggestions to get the download speed up to 25 Mbps before I switch back to my E1000? The E1200 router is connected to my Arris TM602G modem. Both modem and router were reset during the installation process. I setup parental controls for a couple of iPods and configured Open DNS, but other than that, the router is using default settings. All wireless devices in the house seem to be performing fine with the E1200.
I am getting very slow window file transfer speed (4 Mbps per second) between two connecting servers in Cisco 6509 switch. I have connect the two laptops in 6509 switch in same module using the same vlan and try to copy the files from one laptop to another and vice versa and got the same speed on 4 to 5 Mbps per second. Switch utilization is not more than 10% and both the laptops are connected in 1 Gbps full duplex.
I have checked by removing the gateway in both laptop but the output is same.
I just discovered that my wireless download speeds are 5Mbps, compared to 16Mbps if my laptop is connected directly to the modem or wired through the router. Uploads are 2Mbps either way. I have a WRT54GS v.6 with firmware version v1.52.8 which I updated today, completed by setting factory default through the router webpage after I discovered this discrepancy. The firmware update did not improve the download speed appreciably, if at all.Should the wireless connection be that much slower than the wired connection through the router? If not, what sort of issues could I be having to account for this?
I did just replace my modem when I discovered I was having erratic speedtests and that corrected that problem. That is when I became aware of the wireless issue, so not sure how long that has been the case. I have Charter's 16/2 HSI, living in a sparsely populated area with solid internet service. There is no external nor internal interference on this 2.4Ghz band.
I have a Arris DLS with 12 Mbps Download and when I Connect my laptop directly I get the same speed as 12 Mbps but when I do the speed test with my linksys I get only 5 Mbps. How to upgrade to the new WRT54GL or WRT54GS?
Recently my desktop has experienced very slow download speeds (~0.11 Mbps), however the upload speed appears to be in line (~2.0Mbps). These numbers are taken from Comcast's speed test (my ISP). It is obviously a problem with my PC because everything else on the network (PS3, Laptop) have great signals with no problems. I just recently reverted the Desktop back to its factory state, and everything was working fine for a couple of months. The desktop in question uses Vista 32-bit and the Belkin Basic USB Wireless Adapter.
I am using Linksys wirelless G router, will my wired speed on desktop increase when I change to a wirelless N router for laptop and ethernet for wired desk top? I don't need anymore wireless speed but am wondering if I upgrade will my wired desktop pick up more speed.
On board NIC: Intel 82579V Gigabit Network Controller (asus sabertooth x79 motherboard)I installed the drivers for it from intel's site.f I set link speed to auto (chooses 100mbps full duplex) or 100mbps full or half duplex, any HTTP downloads get slowed to a crawl (30kbps) (steam downloads remain at normal speeds). If I set it to 10mbps full duplex, download speeds jump to normal (500kbps for most HTTP sources)his happens on just this new computer (wired connection), any other computers on the network (wireless) work just fine
I live in the tampa bay area, I have bright house (BHN) as my service provider, which provides a Road Runner Lightning (40/5) package. I previously used BHN's top tier (20/2) back in July (and prior) with no problems.
After converting to Lightning in August of this year (2010). Of course, BHN (and every other provider) wants to force a modem/router down your throat, so I had them bridge it (in short, turn it into a dummy modem with no routing). I had an SMC branded modem gateway at the time. I work from home 2 days a week (so I can spend more time with my kids during morning, lunch, right after work) and this requires me to use QoS to ensure my VOIP work calls don't get dropped, if the family is watching youtube videos or watching netflex.
My network was as follows SMC Modem >WAN IP>>WAN Port>>D-link DIR-655>>Switch Ports>PC1, PC2, PC3
Everything seemed fine (from a usability stand point) till about 2 weeks ago when my upload speed seemed to grind to halt. Normally I was able to upload about 200-300K per second, and I noticed this dropped to about 45K per second during a drop box upload. First thing I did was power cycle both my modem and router (in the proper/usual order). After they both come up, I start using speed test to find out what my upload speeds were. I was getting about 39Mbps down, but only .56Mbps up still. I factory reset my router.... test, similar speeds. Power cycle all computers (just in case), and then modem/router. Tested, similar speeds. Updated the firmware to the latest. Same issue
Called BHN customer service, they factor reset it, but it wasn't in bridge mode. If I by passed the 655, in factory mode (non bridge mode) upload speeds returned to better than expected states. If I bridged the cable modem, upload speeds seemed to crash.
Had BHN replace the modem, seemed fixed for a day, then issue came back. Had them come back out and replace it again, this time with a Motorolla Surfboard modem... same issue. Fine during factory reset, however after they bridge the modem, upload speeds were fine. Told BHN I would take it from there.. Connected up the DIR-655, and upload speeds crashed again. (.6Mbps). Called D-Link Support, and the Chinese English speaking rep seemed to not be listening to me and tried to have me adjust my MTU as well as Wireless settings. Long story short... the rep was a level 0 id10t and I hope D-link will consider hiring better employees/contractors. So I was all about to give up and replace it with a DD-WRT capable router (which it takes me a lot to want to swap hardware), when I discovered the wan shaping was on. Which I thought to myself... nah... QoS has never messed up before... why would it be the cause. Turned off wan shapping... and voila. Issue seemed to be insta-resolved.
Unsatisfied with that... I decided to dig a lil deeper. I turned on Wan shaping again, but decided to set the settings manually instead of auto detect.
Here are the settings I used... (Advanced Tab>QoS) Enable Traffic Shaping - Checked Automatic Uplink Speed - Unchecked Manual Uplink Speed - 5000 Connection Type: Cable or Other Broadand Network
Enable QoS Engine - Checked Automatic Classification - unchecked (this checked seemed to affect my upload speed by about 5-10% during testing) Dynamic Fragmentation - unchecked (this checked seemed to be the worse enemy for upload speed)
While I know I'm not any network guru (still have to use a subnet calculator for subnetting), I think I did a pretty good job drilling down the issue (once I got passed my service provider replacing modems).
Anyways, I've had overall good luck with D-Link products, even have a 5 port 10/100 switch (all metal) from 1998 that works great. Hopefully, D-Link will just either put more documentation on the web, or hire better employees.
Are the users' download speeds depend on the hosting company's owner's internet speed? Let say if I was running my own server with my internet speed 1mb and LAN 100mbps, are my clients' download speeds restricted to maximum 1mb of any content from my server?
is it possible to assign a loopback address to a typical switch port on a 2950 switch? I want to be able to have some devices connected to a switch to test access lists and VLANs.
I need 10gigbit uplink for this switch. What are the other devices that i need order along with this device.And what is the diff between X2-10GB-LR= and CVR-X2-SFP.if i take CVR-X2-SFP, in future how can i upgrade from one gig to 10 gig?for current use i need 10gig support required. so what are all the other devices that i need to order.Fiber multimode and distance 15Mt only.
I have a problem, i would like todo MACSEC betwwen two switches cisco catalyst 3560-x but I know that for this operation i needed ACS server 5.1 is it possible to encryp dataflow without ACS server and if you have the configuration
i have an issue to connect a trunk between cisco switch and extreme switch i have many vlans that i want to cross via a link between cisco 3750 switch and a Extreme Alpine 3800 switch
I have two 3750-X configured to be a stack and I am planning to re-rack these somewhere else. What I would like to know is what are the effects of having the master switch itself lose power? Does it immediately just make the member take over master (there should be no election since there are only 2 switches??) and there would be no loss of connectivity?
I have a Catalyst 4006 switch in production and a spare switch of same model. I have to quickly copy the configuration from production switch to spare switch (both L2 and L3 configurations) How do I do that?
I have a 2 cisco switches that are at different sites one is a Cisco CAT4500 and other 3560. The connection between the switches is a layer 2 fibre link. CAT4500 and 3560 both have VLAN interface ip addresses in order for me to connect to the switches.
I have PC A connected to CAT4500 and PC B connecting to 3560. All these devices are the same VLAN and in the same subnet. I do have trunk links all the way though allowing this vlan as we run vlans. From PC A, I can ping CAT4500, 3560 and even PC B. This tells me everything is fine regarding Layer 2 & 3.
As soon as I move PC B and connect it to the other switch CAT4500 or move the other PC vice versa (this happens in both directions). Both switches learn that the mac address has moved locations and updates its mac address table accordingly. So when I do a show mac address table and show arp, everything has learned and moved fine. However when I try to ping any other device from PC B I cannot. So the 3560 switch PC B was originally connected to, I can no longer ping, the switch cannot see the pc also. It is as if PC B has not learned anything from the switch and cannot respond or reply to any icmp. I have tried this with different end devices, same thing. I am now thinking it has something to do with the switch.
I have a small home network of around 5 PCsI have 8MB shared connection from ISP so when I run speed test check from one of my PC it returns around 1.76 Mb download and 0.07 Mb Upload Speed my question is, if I connect one of the PC directly to modem and run the test again so will I get 8MB of speed?
