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.

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

What are the limitation of the 4 Port Gigabit ethernet Security Service Module (4GE SSM)?

I was wondering if anyone can help me out. I am trying to create a redundancy topology which require several connections to an ASA 5510. I am looking at extending the connections to my ASA 5510 appliance with the four port gig ethernet security module (4GE SSM). I am trying to find out what the limitations are on this particular module.
I have heard that there might be limitations to the 4GE SSM. Such as the interfaces on this module might process data separately from the ASA 5510 appliance. My question is does the ASA four port gig ethernet security module (4GE SSM) interfaces act as a extension of the ASA 5510 appliance or does it process and filter data separate from the ASA 5510 appliance ?
My concerns are that the 4GE SSM does not utilize all the security features of the ASA 5510 appliance, and that it just separates traffic into security zones. I interpret that to mean that each interface can be placed in a separate security level in which case has a separate security algorithm and uses the security level to force security policies. Nothing more.
My second question if relevant would be what are the limitations?
Thank you for your help on this topic.
mike

The 4GE SSM just gives you the four additional ports. It doesn't increase the processing capacity of the 5510 (a relatively low end box whose replacement - the 5515X - has been out since this past spring). It works off the same configuration script and CPU as all the built-in ports.
The only limitation I can think of off the top of my head is that members of an Etherchannel cannot span the SSM and the built-in ports.

Gigabit ethernet only supports 100Mb

Hi
Im having a problem with the 48-port Gigabit ethernet blade (48-port 10/100/1000BaseT (RJ45)) on a 4506 switch, one of the ports only support 100Mb, if hardcoded to 1000Mb on both sides, then the connectivity would be gone. All other ports on this blade seem fine.
Would it be a hardware issue? Any idea what caused it?
Thank you
Jane

Not at this point, no.
Any diagnostics, with or without testing equipment, are going to require disconnecting either or both ends of the cable.
You can follow the cable through the system and inspect all of the connections (patch cable->panel->info outlet->patch cable to the host), maybe try re-punching the connection at the panel to make sure the wires are seated into the IDC connector.
You'd be looking primarily at the blue and brown pairs (green and orange are used for Ethernet/Fast Ethernet).
Likely as not, one of the blue or brown pair are reversed (i.e., white-blue and blue are swapped at the panel).
If that's the case, you'll need to clear and re-punch the pair.
Good Luck
Scott

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?

MDS9222i Gigabit Ethernet Ports

Hi all,
I have a question about MDS9222i Gigabit Ethernet ports. Are they RJ-45? In other words, to connect one of them to a Gigabit Ethernet RJ-45 port on a Catalyst 4500 supervisor, do I need just a Cat 5e copper cable or are SFPs required?
Thank you in advance,
Gianluca

The mgmt interface supports copper,The 4 ip gigabit interfaceS require a SFP. There is a RJ-45 copper option: DS-SFP-GE-T, or a MM fiber option: DS-SFP-FCGE-SW

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.

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:

Using both Dual Gigabit Ethernet Ports

Using both Dual Gigabit Ethernet Ports
If I plugged both of my ethernet ports into my LAN switch, that would double the bandwidth to and from my machine. A switch does not used shared bandwidth like a hub does. I realize that it won't speed up any of the other devices that are plugged into the switch. Regardless, I would have the capacity for double the bandwidth to my machine.
All LAN cables are CAT6 and the switch is 10/100/1000.
The question is, would Mac OS X 10.4.7 utilize both ports (soft of the way it uses multiple processors)?

It's easy to try... it's call "Link Aggregation"...
http://docs.info.apple.com/article.html?artnum=304120
You get to it by Network>Show>Network Port Configurations>New then Port in the popup, then you schould see Port Aggregation. Selt the two ports you wish to combine.

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

Will any Cat5 Ethernet cables work equally well for Gigabit ethernet ports?

I'm almost embarrassed to ask this, but I must. Are some Cat 5 Ethernet cables designed for Gigabit Ethernet? The Airport Extreme Base Station(b/g) uses Gigabit Ethernet for its LAN and WAN ports. I think my Comcast modem's single Ethernet port does, also. Currently, I use a Cat 5 100Mbs cable to connect the modem to the AEBS. So, I'm wondering if I can get faster throughput with a Cat 5 1000Mbs cable (if such a thing exists).

In addition to Bob's comments, it's important to understand that Gigabit Ethernet requires using all four pairs of wires inside the cable ... regardless of whether that cable is CAT-5, CAT-5e, or CAT-6 certified. The real difference of the categories is how high of a frequency can they support. For example CAT-6 is rated for 10 Gigabit traffic. It's not that CAT-5 won't work, but it's not guaranteed to do so.
If you have any Ethernet runs in home that is supplying connections for both data & phone lines on the same cable, you will NOT achieve Gigabit speeds on those cables as the installer used at least one of the necessary pairs for the phone line.

Will on-board Gigabit Ethernet ports on a Cisco 3845 support a 100 Mb SFP?

Hi,
This is a very specific question - hopefully someone has tested this or run into this scenario...
I was trying to connect a Cisco 3845 router to a 100 Mbps circuit. Specifically, I was trying to connect this circuit to the on-board Gigabit Ethernet port (Gig 0/0). This is the port that can be used as either an RJ45 or SFP slot. The only SFP I had was a multi-mode 100 Mbps SFP. When I hooked it up to Gi0/0, I got a message saying the SFP type wasn't supported on the chassis.
I was able to deploy the 3845 and since then I haven't had the correct hardware to recreate the exact scenario. Has anyone experienced this? Is it simply because Gigabit interface on a 3845 won't support a Fast Ethernet (100 Mbps) SFP?
Thanks.

Not all SFP's will just plug in and work. Here are the SFP's that are considered compatible with the 3800 series ISR's.
GLC-LH-SM= Gigabit Ethernet SFP, LC connector, LX/LH transceiver
GLC-SX-MM= Gigabit Ethernet SFP, LC connector, SX transceiver
GLC-ZX-SM= 1000BASE-ZX SFP
CWDM-SFP-1470= Coarse wavelength-division multiplexing (CWDM) 1470-nm SFP Gigabit Ethernet and 1G/2G Fibre Channel (FC)
CWDM-SFP-1490= CWDM 1490-nm SFP Gigabit Ethernet and 1G/2G FC
CWDM-SFP-1510= CWDM 1510-nm SFP Gigabit Ethernet and 1G/2G FC
CWDM-SFP-1530= CWDM 1530-nm SFP Gigabit Ethernet and 1G/2G FC
CWDM-SFP-1550= CWDM 1550-nm SFP Gigabit Ethernet and 1G/2G FC
CWDM-SFP-1570= CWDM 1570-nm SFP Gigabit Ethernet and 1G/2G FC
CWDM-SFP-1590= CWDM 1590-nm SFP Gigabit Ethernet and 1G/2G FC
CWDM-SFP-1610= CWDM 1610-nm SFP Gigabit Ethernet and 1G/2G FC

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.

Dual Channel Gigabit Ethernet on MBP!?

Hi all,
I have a MBP with the ExpressCard/34 slot.
I am wondering, if I get an ExpressCard/34 to Gigabit Ethernet Card can I create a dual channel setup using the MBP's existing Gigabit port and the port on the Express/34?
If this was possible do I also need XSAN?
Cheers

Ned the point of the benchmark is (at least with the Core Duo) that the FSB limits memory access to 5.33 GB/s. Single Channel PC2 5300 667MHz RAM has a bandwidth of 5.33 GB/s. So what does doubling bandwidth via dual-channel to 10.66 GB/s do for you if the FSB is limiting it to 5.33 GB/s anyway. You can saturate the bus twice as fast? It is still saturated.
I am not speakng of saturating RAM, but rather saturating the FSB which is where the bottleneck occurs.
That is what the test is designed to show.
That is why I say that the benefits of 3GB outweigh the benefits of dual-channel. At least in terms of the Core Duo what are you really gaining from the dual-channel? In theory..nothing...in testing...nothing.
Nothing will slow down performance like paging out to a slow hard drive however.
edit
Not trying to be argumentative on this, I just have not seen any evidence of dual-channel having any signficant benefit to performance that would warrant being afraid to give it up for 3GB single-channel.
From Barefeats:
DO MATCHING PAIRS OF MEMORY HELP?
Though we ran the tests above using matching 1GB SODIMMs in both MacBook Pros (for a total of 2GB), we also ran the same tests in the 15" MacBook Pro Core 2 Duo with one 1GB SODIMM and one 2GB SODIMM for a total of 3GB of memory. We wanted to see if non-matched modules would cause the MacBook to slow down due to the loss of interleaving.
The answer is "no, it didn't slow down." In some cases we saw a gain in speed. An example is Aperture where the "lift and stamp" ran 11% faster with 3GB of RAM. But that's probably due to the fact that Aperture + OS X = more than 2GB of total memory usage.
