15305 and 15454 Ethernet interworking

Hi Folk,
Wonder if anyone can help out there.
Would like to provide a LAN Extension service over an SDH network. Does anyone know whether the GigE and FE cards on the 15305 interwork with the 15454 CE or ML ethernet cards?
Have looked on the Cisco site and am somewhat confused. The 15305 uses GFP-F to map Ethernet into SDH. The 15454 cards appear to encapsulate the ethernet frame before it uses GFP-F.
Could someone enlighten me!!
Regards,
Phil

Hi Phil
yes, of course they do. You have two possibilites. You can use the 15305 modules in L1 mode and connect them to the CE cards on 15454. Or you can use the 15454 ML cards, maybe with a L2 RPR ring. Then you can switch the 15305 modules to L2 mode with a integrated L2 switch.
CE cards anf the 15305 modules in L1 mode is always P2P and pure ethernet transport without any L2 or VLAN stuff.
ML card and 15305 modules in L2 mode use a L2 switch with a lot of L2 features, like VLAN, STP, QoS and so on.
By the way, both CE and 15305 modules in L1 use GFP-F and are fully compatible.
I hope this helps. Please rate all posts.
Cheers
Rene

Yes.
You can have one HDMI (or DVI monitor via HDMI to DVI adopter) on the HDMI port
Another monitor via one Thunderbolt port and suitable adopter if not a displayport/mini displayport monitor
And use the other Thunderbolt port for Ethernet via a Thunderbolt to Ethernet adopter.

IMO, wrong choice. Start over, using a FireWire cable and following the steps in Pondini's Setup New Mac guide.

Wifi connecting while turned off and on ethernet

Much the same as a lot of people I have been experiencing wifi issues, lost connections after sleep and usage speed etc, and after messing about with settings and a clean install decided to just turn off wifi and use ethernet until apple can sort out the complete mess that is OS X 10.10.
So... with Wifi turned off and ethernet connected via thunderbolt, approx every 20mins wifi turns it's self on and connects to my network for about 30 secs and then turns off. I get notified of this via little snitch and have monitored this via Network settings. I have tested this from both my existing and a new account.
Would anyone have any idea as to why this is happening?

I saw a thread like this a few weeks ago but don't remember if they reached a solution. I'd do a search of the iPad forum and see what comes up and read through them.
Good luck.

15454 Ethernet Protection & Provisioning

Is anyone using E100T-G Ethernet cards in Cisco ONS transports forconnectivity? We are just starting and cannot seem to find an answer to a nagging question (after much RTFM and TAC runarounds). Our topology is a 15 node UPSR SONET. We currently have 3 nodes each with a 12-port E100 card. Node1 Port2 connects to Node2 Port2. Node1 Port3 connects to Node3 Port3. Everything is on the same VLAN (default). Now my question is of protection. When we setup any other type of circuit (DS1 or DS3) the circuit is created to be protected by default, the software provides a working and protected path. But when creating ethernet circuits there is no such option. So when looking at the circuit list under the Protection column instead of the "UPSR" listing like all the rest of the circuits, for the Ethernet we see "Unprot". Try as we might we cannot find a way to make these circuits protected. At this point we assume that if there is a fiber cut or loss, the whole ring will switch from the working ring to the protected ring and the Ethernet will go right along this path as well. We are going to be installing a couple more nodes next spring and we plan to test this by actually pulling the OC48 connections out while it is running (without live traffic of course), but in the mean time we are perplexed by this problem. If anyone has any thoughts, ideas, or suggestion on provisioning Ethernet and how to effectively and efficiently use Ethernet in a network, we'd love to hear from you.

You have several options then. If you leave your cards as a multi-card or single-ether card then they will operate as a Layer 2 switch. The E-series cards operate well as a switch but do not have all the features that can be found in the ML series of cards. One of the options is to utilize these cards at L2 with this method you can segment all your remote sites back on individual VLANs to your aggregation site. The protection mechanism in this case can either be individually protected circuits, however this can consume quite a bit of bandwidth with only STS granularity for provisioning these circuits. You can also map your circuits from card to card all the way around your ring. This allows you to create unprotected circuits and rely on Spanning Tree to protect your traffic and re-route in the event of a fiber cut. Bear in mind that Spanning tree can take up to 50 seconds per switch port to complete a topology change. In my experience on a 16 node ring with E-series cards, spanning tree can take as long as 3 or 4 minutes to complete and put all the ports back into forwarding. This time period may be unacceptable depending on your situation.
Alternately, you can provision your E-series card as port-mapped which changes them to a layer 1 card. You can then connect a switch to the ports in your remote sites. With a switch such as a 3550 you can implement RSTP (Rapid Spanning Tree) which can reduce your convergence time using rapid spanning tree to sub 1 second.
The ML card provides another option to implement a great Ethernet topology that includes RPR (Resilient Packet Rings) which provide for sub 50ms failover and spatial re-use. This is a greatly improved method of delivering metro Ethernet services and in addition support eoMPLS (Ethernet over MPLS) which can provide you some features that you can use in your own network as well as offer as a premium service to commercial customers.
Let me know if you would like to expand on any of these topics.

WAN port inop and PM ethernet port inop - options to connect to AEBS?

Hi. We had a thunderestorm last week at home and we shut everything down and unplugged the power cords, but I think the cable to the cable modem fried some of my ports. I have a cable modem hooked to the WAN AEBS port and a cable from the LAN AEBS port to the ethernet port of my PM G4 867 (Quicksilver). After lots of troubleshooting with a different cable modem and my PB 15, it seems that the AEBS WAN port is dead and the ethernet port of the cable modem AND PM G4 are toast!!:( I guess all three got fried thru the cable.
I have a different cable modem that runs my digital phone so I connect thru it's ethernet port (after provisioning it). It works with my PBs directly and my airport express. I went to the Apple store and they confirmed the WAN was inop. Got a new AEBS. Now, here's my question:
I connect my PBs thru airport, but used the LAN to directly connect to the PM G4. The ethernet port is dead too. What should I do to get the PM connected?
I think the PM G4 quicksilver can accept an airport card (older kind). I can get one for around $100.
Is it easy to replace the ethernet card/port on this model? How much?
What's the best solution? What would you do? Thanks for your help.

I think the PM G4 quicksilver can accept an airport card (older kind). I can get one for around $100.
Yes the QuickSilver has an internal slot for the original 802.11b AirPort card. That slot is NOT compatible with the AirPort Extreme card.
Is it easy to replace the ethernet card/port on this model? How much?
There is no separate Ethernet card. The Ethernet port is built into the motherboard.
If you want Ethernet, the least expensive solution is a compatible PCI Ethernet card.

How do I create, send and receive ethernet packets to UUT

I need to create and send ethernet packets to control and communicate with an RF board. I would also like to receive ethernet packets back which would be parsed and interpreted.

There you are!
I was wondering how this project was going.
As I said before, we need to know what protocol is being used.
Let me eaxplain. (Please refer to the diagrams and tutorial on pages 752-755 of 2002 NI catalog.)
802.3 is the spec for ethernet. It defines how packets will be transmitted on the wire.
Real Life analogy:
US Mail service.
It moves messages from one place to another. It defines that messages should be in an envelope. The Envelope must have a address so they know where it should be delivered to. You should also have a return address (but this is not enforced). Inside the envelope, you can put any kind of message you want as long as the person recieving it knows how to read it. The
reciever can look at the message and say "oh, this is english, I will read it in english".
Ethernet is similar. Ethernet (ignoring the electrical specs) defines a packet as consisting of
Source address (return address in US mail)
Destination address (delivery address)
Protocol (pretend there was a mark on the envelope that said this letter is in French).
Data (the letter itself)
Checksum (letter pages number as 1 of 4, 2 of 4, etc).
So what you have told me so far is that you want to send a letter!
You have been asking me how to comunicate with the other person but you have not told me what language they speak!
There are many different languages (i.e. protocol's) possible with 802.3.
Examples are
TCP/IP ( say this is English)
UDP (French)
etc....
LV has built in VI's to take a message and convert it to the protocol (lanuage) you want and send it on it's way.
So my question to you once more is;
What protocol are you using?

Use TC as a wireless client and as ethernet switch hub at the same time?

Hi!
I have a wireless DSL-modem downstairs and my office upstairs. Since I use the TC-USB Port for my printer (to share it to my family as well) my TC is located in the office, close to the printer. Thus TC has to be configured as a wireless client and everything works fine so far,........but: When I add music (stored on TC) to my iTunes library, everything is soooo sloooow! Copying files using the route iMAC ---> DSL-modem/router ----> TC .... so sloooooow!
Is there any way to use the ethernet ports while TC is a wireless client?
Whenever I connect my iMac via ethernet using my current setup, it doesn't get an IP address from TC (obviously because there is no DHCP service active???). When I disable my Airport on the iMac, all connections are off-line.
Pls. help or advise!
Thx. Hannes

Thanks for the response.
Everything works fine if I use your suggested setup but I need the TC in the office, and the DSL modem downstairs. An ethernet connection is not possible this way, and the printer in the living room isn't really a nice piece of furniture
I think, there is no possibility to use the wireless as uplink and the TC as a router/DHCP-server...
Probably I need a server computer to handle the connection between the wireless LAN created by the DSL modem and an ethernet network managed by the TC.
Hopefully someone has an idea/solution that fixes my problem.
meanwhile I keep looking......

Which CISCO switch supports SFP, SFP+ and 10G ethernet ports

I would like to have information about a CISCO switch which can support fiber ports SFP(1g) and SFP+(10g) and copper 1g and 10g ethernet ports. And will it also software upgradable to support L3 protocols ?

You can choose from the Cisco 3560-E, 4900, 4500, and 6500 series switches. That's in order of capability (and cost!), from least to greatest.
The 3560-E and 4900 series are fixed chassis systems (the 4900M is semi-modular) while the 4500 and 6500 series are completely modular - buy the chassis and populate it according to your requirements.
In addition to the references cited above, also refer to the Cisco Products Quick Reference Guide (CPQRG), available at http://www.cisco.com/en/US/prod/qrg/index.html
Hope this helps. Please rate this post if it does.

WDS with Airport express and Dual ethernet Airport base

Can the airport express and dual ethernet airport base create a wds? I can't find the options on the airport base's software.

coloradoapple, Welcome to the discussion area!
The Dual Ethernet (snow) AirPort base station (ABS) does not support WDS.
Only the AirPort Extreme base station (AEBS) and AirPort Express (AX) support WDS.

Yukon: Ethernet and Airport: Ethernet addresses...

Sorry if this is a stupid question but what is the difference between the Yukon and Airport ethernet addresses? Are they supposed to be the same or different? Many thanks.

Hello,
The first is Ethernet, the second is Wifi or Airport, those are two different interfaces, now as far as addresses go, they have IP addresses, and Hardware Machine Access Code addresses.
To see them, At the Apple Icon at top left>About this Mac, then click on More Info, then click on Network.
It can be confusing how the term Ethernet is used.

Thinkpad 8 - Power and Wired Ethernet at the same time?

Hi. I am looking for a way to have Power and Wired Ethernet at the same time?
I have been looking at USB 3.0 micro cables with a dual USB ports - one for power and one for ethernet (via USB adapter) - but I can't get that to work.
Has anyone tried this? Or found a solution to this?
Thanks!

Lenovo sells a y-cable for the TP8 that does this. Look here. I've not been able to find any cheaper alternatives so I just ordered one of these myself.

HT4796 Migration assistant is telling me that it has lost connection with my Mac and to ensure they are on the same network. They are, and an ethernet cable is plugged into them. What do i do?

Migration Assistant has been running since yesterday evening. My Dell is now telling me that its trying to reconnect to my Mac and to ensure they are both using the same network. I have an Ethernet cable plugged in them and they are both on the same WiFi. What can I do?

Hello Wyodor,
thanks for your reply on my question.
You are wright the index file is 308 KB.
And offcourse that I delete my files and documents is not an Iweb problem, but because my English is not that good, that I thougt I try to tell the whole story, and hope people can read trough the lines.
Why I didn't use Iweb to upload to the server is because the server company recommanded to use file zilla. And I am a nobody with this kind of things, so I did exactly what they tell me to do.
No, i did not make a backup of Iweb and the domain file, but reading other messages on this forum showed me that I can maybe try to make empty the cashfile (?)
and otherwise I have bad luck and have to make my website again. Offcourse I have a lot of examples from all the pages (copied from the local map to my USB stick) and my website is aprox. 15 Mb, (not so big) so it will cost me a few nigths.
But I'm still hoping on a miracle :-)
greetings Lasource

I am connected to a time capsule both wirelessly and through ethernet...and state of the time capsule is solid green...the internet however doesn't work...The internet works fine when directly connected to my macbook pro but it won't work through the tc

I have deleted time machine preferences...restarted the modem a bunch of times, restored time capsule to it's original settings...after I first set it up in Airport Ulitity its shows a page quickly that states there is a internet problem, but the page quickly goes away before I can read what it says exaclty and states the internet connection problem is resolved...
However it's not resolved, I'm also having trouble doing a back up to my time capsule...I recently purchased a new macbook and retrieved/restore what was on the time capsule to the new computer...that worked fine...wireless worked fine...however when I tried to back up the new macbook...it would faii stating that there isn't enough room on the TC to do a back up...
I didn't end up keeping the new macbook, I was just using it/trying it out while my current macbook pro was being repaired (logic board)
Ever since I got my current macbook back from repair...my backups have failed due to their not being enough space to perform the back up...in the past the back ups would happen and old back ups would be replaced...
I think this has to do with my current computer having a new name after the repair..."Adam's macbook pro 2" vs "Adam's macbook pro"
The internet was working fine wirelessly through the TC a day ago, but it wasn't allowing my other laptop that was connected via ethernet access to the internet...I had a self assigned IP address error then...I don't have that problem now, but it's not transmitting internet at all...even though it's in a solid green state.
I have no problem completely wiping out my TC including the previous back ups on it...just don't know how to go about it...I have restored it to factory settings a bunch of times and created the network from scratch...just hasn't fixed the issue
Is there more prefences files I should delete

If the modem is also a router, either use the modem in bridge and run pppoe client on the TC.. that is assuming ADSL or similar eg vdsl. If it is cable service.. and the modem is a router, then bridge the TC.. go to internet page and select connect by ethernet and below that set connection sharing to bridge.
Please tell us more about the modem if the above gives you issues.
