Which port is better usb or gigabit ethernet?

My Canon printer has USB 2.0 and an Ethernet port. Is there a performance or functionality preference?
My Airport Extreme base station has both types of ports as well.

Mac Mini Server Link aggregation - Thunderbolt or USB 3 gigabit ethernet adaptors

I am setting up a late 2012 Mac Mini as a file server with Server 2.2. It has a Promise Pegasus R4 RAID and LaCie 4TB drives daisy chained via the Thunderbolt connection. 4 users on MacPro's will connect to the server to access these hard drives via gigabit ethernet.
I imagine the gigabit ethernet will be the bottleneck, so I'm now looking at link aggregation. Not a problem on the MacPro's but the Mac Mini will require an adaptor to get a second gigabit port. From reading this forum I understand the Apple Thunderbolt to Gigabit adaptor will work, but I'm concerned that it will need to be fitted 3rd in line after the R4 and LaCie drives. The 10Gbps bandwidth Thunderbolt has, may cause another bottleneck with all three working off the same port?
An option would be to use one of the USB 3 ports with this adaptor http://www.ebuyer.com/412005-startec...edium=products
I believe it work with OSX, but I have no speed information or if OSX link aggregation will work using it.
Any thoughts on the above would be appreciated and recommendations on a suitable Network Switch with LACP support welcome.

At present Mountain Lion Server cannot use a LACP bond, in my experience only of course. http://www.small-tree.com/kb_results.asp?ID=59 describes LACP/Bonds do not show up in Server Admin GUI on Mountain Lion
anyone know how to do it? or the location and the name of the plist file to configure the network interface in ML server?

A dv9000. Which port is the usb 2.0?

My Device Manager says that out of my four usb ports, three are usb 1.0 and one is an enhanced usb 2.0 speed, but there are no markings, or any way to tell which is which. Does anyone know how to tell? Thanks in advance..

There's no number beside Service tag
Incidentally, I called HP tech support with this same question and I was told that, because my warranty had expired, I'd have to purchase a service contract to "UNLOCK" this information.
There's nothing listed in the user guide. Imagine!! I have to pay for information pertaining to my computer specs. I wasn't asking for him to fix it...just give me specs that should be in the user guide.
That's enough reason to shop at another place for my next computer.
I'm not the good representive I used to be for HP.
Thank you for whatever help you can give me on this matter.

Which is better Gigabit Ethernet DP or Quicksilver SP

Hello
I'm fairly new to the Mac only been a user for 2.5 years, versus Wintel 20 years.
Well a brief history I started out with a iMac G3 600MHz/1GB/40GB/CD-RW/16MB Rage 128 in April 2008 then moved onto a PowerMac G4 Quicksilver 2001 733MHz last September its mostly stock except upgraded to Tiger 10.4.11, maxed RAM to 1.5GB, added Pioneer DVR109 SuperDrive, & had to downgrade processor due to daughter-card failure its now got a Digital Audio's 466MHz Clock/133 MHz Bus/512K L2 Backside Cache CPU.
But anyways just got given a PowerMac G4 Gigabit Ethernet Dual Processor 450 MHz/2GB RAM/Pioneer SuperDrive/Rage 128 16MB tower so my questions are.
Which would be better the QS or the GE? any advice &/or opinions would be greatly appreciated, thanks in advance.
Also can I install the QS's AGP 4X Geforce MX2 32MB video card into the GE's AGP 2X slot?
I realize by CPU the GE beats out the QS by leaps & bounds., But the QS has both 133 MHz RAM & Bus versus the GE 100 MHz RAM & Bus, the QS also has a AGP 4X slot instead of the GE's AGP 2X slot, but the GE also can have 2GB RAM too instead of the QS's 1.5GB.
Yours Truly: A fellow Mac Head
PS Have a good evening, take care.

Hi SLCUTUSA, and a warm welcome to the forums & belated Macdom!
Difficult call you have there, the QS is faster, the DA more indestructible.
Depending which 733 it is, (one was a real dog), the DP/450 may be faster too.

Combo USB 2.0 + Gigabit Ethernet PCI Card?

I have been looking feverishly for a manufacturer that makes a Mac-compatible PCI Card that has both USB 2.0 and Gigabit Ethernet on the same card. So far I have not been able to find anything. I am wondering if anyone knows of one that will be compatible with a B&W Powermac with a gig of RAM and a Sonnet G4 500Mhz processor.
On a side note, I know this Mac has limitations pertaining to Hard Drive size and I am curious: If I have a slave drive enabled, is my total combined usable size the 128 limit or can I have 2 120 gig Hard drives? And what is the highest speed drive recommended for the B&W's slow bus?
Kind of a lot of questions... Thanks so much in advance!!!!
-Kurt

I don't know of a Mac-compatible combo card like that. Because of the issues with USB 2.0 cards in Macs, you'll have better compatibility installing one that has an NEC controller chip. This stipulation would narrow the field of recommended combo cards even further, if there were any from which to choose. As for hard drive capacity, the 128 GB limitation applies to each drive - not the sum of two drives, configured as master and slave. If your B&W G3 has a Rev. 1 motherboard, the onboard IDE controller doesn't support master/slave configurations (see "New Features" Section 3 - "Revised IDE Controller Chip" on this page). Depending on the amount of money you wish to invest in your B&W, this Acard AEC-6280M ATA-133 controller card would enable you to take advantage of reasonably-priced, larger capacity drives. About six months ago, I bought a pair of sale-priced Seagate 120 GB drives for $59.99 USD each, when that capacity was being phased out by the retailer. Now, you can often find larger capacity drives for less than that. As for bus speed, an ATA-100 or ATA-133 drive is backward-compatible and will run on the slower, onboard IDE bus in the B&W. The spindle speed for most drives is 7200 RPM, which provides a slight improvement over the slower 5400 RPM drives.

Thunderbolt to Gigabit Ethernet Adapter or Thunderbolt port stopped working

Hey problem if anyone can help:
I use a Thunderbolt to Gigabit Ethernet Adapter, and all of a sudden it stopped working to connect to the internet on my Macbook Air (MacBook Air (11-inch, Early 2014 with OS X Yosemite 10.10.1 (14B25)). In my system information it says it is connected even when not, see below:
Thunderbolt to Gigabit Ethernet Adapter:
Vendor Name: Apple Inc.
Device Name: Thunderbolt to Gigabit Ethernet Adapter
Vendor ID: 0x1
Device ID: 0x8003
Device Revision: 0x1
UID: 0x0001000202DD0A30
Apple Serial Number: DTN4263048VDWKHBQ
Route String: 1
Firmware Version: 5.5
Port (Upstream):
Status: Device connected
Link Status: 0x2
Speed: Up to 10 Gb/s x1
Port Micro Firmware Version: 0.0.8
Can anyone help me figure out what the issue is? Is it the Adapter, the Thunderbolt port itself? A gremlin? Thanks!

Which model MacBook Pro do you have? Does it have a Thunderbolt port? If so the TB->Ethernet adapter MAY work (although it's specifically designed for those MacBook models that lack an Ethernet port).
The adapter would certainly be the cheapest way to go - if it works. Personally, I would rather have the Ethernet port on my MacBook Pro working, but this may be an expensive fix, I don't know. If I were you, I would at least take your computer to your local Apple Store/AASP and get a free diagnosis and estimate to repair your MBP. If it seems as if it's going to be too costly, then you may certainly try the adapter and see if it works.

Gigabit Ethernet distribution system ports

Hi,
we are using Cisco WLAN controller 5508 which have 8 Gigabit Ethernet distribution system ports. Can any one tell me how to check the model number of the gigabit Ethernet distribution system ports.
Regards,
Noman

Noman,
I’m still a little confused, sorry. Are you looking for the model of the installed SFP transceiver module or the part number of the SFP port bank itself?
Are you looking for this:
Or this:
If you want to know the transceiver module, you can look at the show port summary command. It will tell you what type of transceiver you have in there, although it won't list the exact make/model but you can figure it out. 1000BaseTX = GLC-T. 1000BaseSX = GLC-SX-MM. 1000BaseLX = GLC-LH-SM.
If you want to know the part number for the SFP bus, ports or chips themselves, then I'm at a loss for you. I guess you can take the controller apart and do a visual inspection to see if you find anything useful. Are you trying to DIY repair a dead controller or something?

Gigabit Ethernet Ports

Can anyone tell me which BT Home HUBs support Gigabit Ethernet, as I wish to obtain a Western Digital MYBOOK WORLD EDITION 2TB Harddrive. So I can Network my Desktop and family Laptops for file sharing and backing up all home computer systems etc. Any info would be helpful on this topic, many thanks in advance.

Hi dynastyuk,
There are some other really cheap alternatives around for gigabit ports...
This for example:
http://www.google.co.uk/products/catalog?hl=en&q=gigabit+switch&cid=18212157716750550582&ei=O2BUTZ2W...
12 quid for a gigabit switch (Just connect all gigabit capable devices into the switch and connect the switch to the homehub)
I hope this helps

Can the Gigabit Ethernet LAN Port be used with a Thunderbolt to Gigabit Ethernet adaptor and then to a Thunderbolt Hard Drive as a back up drive?

Can the Gigabit Ethernet LAN Port be used with a Thunderbolt to Gigabit Ethernet adaptor and then to a Thunderbolt Hard Drive as a back up drive?

If you use ethernet to connect the two AirPort Extremes together, you'll have Gigabit speeds available at all of the ethernet ports on both routers.
If you connect the second AirPort Extreme using wireless only and configure the Extreme to "extend a wireless network", then the maximum speeds that the second router can attain will be limited to the capability of the wireless connection. So, if you connect at normal "n" wireless speeds of say 130 Mbps, that will be the maximum speed available at the ethernet ports on the second AirPort Extreme.
I think you can easily see the difference between Gigabit ethernet, which is 1000 Mbps compared to "n" wireless at 130 Mbps. Even if you can manage to connect at 5 GHz speeds for wireless, the max speed will be in the 300 Mbps range, more than 3 times slower than Gigabit ethernet. Normal "n" speeds will be about 7 times slower than ethernet.
For streaming high definition video and other demanding sources, you'll need as much bandwidth (speed) as you can get. Ethernet is always the best choice if you can possibly use it. And...there's no wireless interference on an ethernet connection.

Add the Kanex USB-C to Gigabit Ethernet Adapter to your Mac Accessories assortment

Best Buy should get the Kanex USB-C to Gigabit Ethernet Adapter (MFR # KU3CGBT) into its stores as soon as possible. Here are some arguments FOR this: (1) Demand for the new MacBooks is at an all-time high. A check for availability of these are various Best Buy stores shows them unavilable with extended backorder times. I know from people that work at Best Buy that as soon as stores are receiving these they're selling either by online purchase or in-store pickup. (2) Apple does not make a competiting adapter and the price ($29.99) of this adapter is in-line with other third-party (Belkin, Insignia) adapters. (3) It is an essential adapter for business custmoers and students alike. My local store is located near a University and I can tell you that they do not allow students to have ANY wireless devices enabled in on-campus housing. This means that the Thunderbolt to Gigabit Ethernet Adapter and this adapter are both going to be in VERY high demand. Judging from last year, you could not find a Thunderbolt to Gigabit Ethernet Adapter within a 150-mile radius of where I live because neither Best Buy or Apple Store was prepared for the increase in demand on this SKU and were both consequently sold out. (4) Kanex accessories generally have 4-5 star reviews which shows they are of sufficient quality and are well-received by customers. (5) You will see USB-C showing up in other non-Apple devices like Chromebooks and PCs as adoption picks up later on this year and next year (example: Google's new flagship Chromebook, the Pixel, is already supporting it so I don't anticipate other OEMs being far behind on adding it to their newer models too).

This product is currently available on BestBuy.com, but I can certainly see where carrying a product like this in our stores would have advantages. Who else would like to see us carry the Kanex adapter in our stores?
Remember to vote for an idea if you like it!

What is faster thunderbolt or usb 3.0 gigabit ethernet

What is faster a thunderbolt to gigabit ethernet adapter or a usb 3.0 gigabit ethernet adapter?
Thanks

Both Thunderbolt and USB 3.0 have bandwidths that exceed gigabit ethernet so based on theoretical numbers they should perform the same. However, different product manufacturers will write different drivers and use different hardware so unless you test specific products the question can't really be answered. Probably have to wait until magazines such as MacWorld or other Mac related websites test and compare devices.

Moshi USB 3.0 to Gigabit Ethernet Adaptor

I just bought a New Macbook Pro late 2014 , I saw the Moshi USB 3.0 to Gigabit Ethernet Adaptor , My internet speed is up to 195 Mbps . Is it good to buy it or the 2.0 where the deference is only $5.00 but forget about money wise sometimes i might use the ethernet RJ45 to connect when Wi-Fi is slow since my other Macbook Pro was slow and i read a lot to do with Yosemite ? What can someone tell me about it ? Is it a good product i read 3 reviews and one was good and the other two where so so.

Did not get any replays but already bought it will get it tomorrow March the 11th where it is my Birthday .

CRS-1 8-Port 10 Gigabit Ethernet Interface Module

How much is the back plane speed for a line card on CRS-1? Does using a 8-Port 10 Gigabit Ethernet Interface Module in CRS-1 have an oversubscription of 2:1, like the WS-X6708 in 7209 chassis?
Thanks

Hello Jenny,
yes from datasheet it looks like so
see
http://www.cisco.com/en/US/partner/prod/collateral/routers/ps5763/ps5862/product_data_sheet09186a008022d5e9.html
or
http://www.cisco.com/en/US/prod/collateral/routers/ps5763/ps5862/product_data_sheet09186a008022d5e9.html
it talks of a 40 Gbps forwarding engine
described here:

http://www.cisco.com/en/US/prod/collateral/routers/ps5763/data_sheet_c78-553673.html
so depending on applications you may prefer a 4 10GE linecard
Hope to help

4-Port 10 Gigabit Ethernet Fiber Module

Hi,
We are using Cisco 6509 and I need to add another 4-Port 10 Gigabit Ethernet (Fiber) Module. kindly let me know how many such module can be added and these are hot swappable.
Thanks

Just to add to Jon's post, it should be up to seven with dual sups or up to eight with single sup.
(Line cards are hot swappable, but I agree with Jon, ideally they should be changed during planned maintenance - just in case.)
BTW, if you're going to load up a 6509 with that many 10g cards, you may want to insure some or all have DFCs. If you do use DFCs, don't forget possible issues when matching them to sup.
Also BTW, if you need even more 10g ports, there also the 6708 and 6716 line cards for sup720s, but if you have a sup2T, there's also the 6816 and 6908.

Minimal interframe gaps in gigabit ethernet port

Hi ,
Whether someone know the minimum interframe gap in gigabit ethernet port in Cisco switch ,3750.
Also ,would like to know the IEEE standard for the same.
Thanks in advance,
Thomas.

the interframe gap for 1-GB is 96 nanoseconds of 96 bit size.
the minimum IFG for is 96 bit times. (the time it takes to transmit 96 bits of data at the specified data rate)
ie:
10Mbps - 9.6 milliseconds
100Mbps - 960 nanoseconds
1000Mbps - 96 nanoseconds
note: you may not want to decrease an IFG smaller than 9.6 microseconds if all other hosts are only capable of 9.6 ms. (10mbps connections)
interframe gap shrinkage could occur to the point where the gap is too small.
if you have a gap that is too small, it will not allow the NIC enough time to switch between TX/RX states and packets could be lost.
please see these links for more IFG info:
