AS5350 Redundency (two ethernet ports) ?

Hiya,
The AS5350 has two ethernet ports. However, I am unable to find supporting information as to why ?
I assume it's for redundency. However, how do Cisco recomend to design VoIP redundency within this AS5350 ? i.e connect two ethernet ports to two different ethernet swicthes.
HSRP is not the correct tool for the job here.
.......... uhhmm, so what's the secret ?
Thanks for reading
Matt C

This can be used as redunant ports only ion case of failure of another. But this should not be confused with a switch port which will be working as a redundancy. Here u have to configure manulayy other port if one fails.

Bonding Two Ethernet Ports to act as One

I am having problems bonding two ethernet ports on my G4 Xserver (10.4.4). The Mac OS X Server Command-Line Administration 10.4 manual gives instructions for doing this a number of ways.
I tried <ifconfig en0 bonddev en1>; it did not work.
The manual suggested using the <serversetup> commmand which does not exist on my server.
I eventually used <sudo networksetup -createBond BondedEnet "Built-in Ethernet" "PCI Ethernet Slot 1"> which looked like it was working. However, it seem to lose the bond after a reboot of the server.
Has anyone had any success with bonding and have some instructions on how to initiate it properly?
G4 Xserver Mac OS X (10.4.4)

I've found bonding to be reliable when set via the
GUI, but I've yet to find a stable command line
method.
Note that any ifconfig commands would be transient,
and lost at the next reboot. In any case your syntax
is incorrect. It should be:
ifconfig bond0 bonddev
en1
in other words, add device en1 to the existing bonded
interface bond0. You're passing in a physical
interface as the first parameter instead of the
virtual bonded interface.
The networksetup command should work, and should be
persistent. It's not clear why it isn't working.
If you have ARD or a monitor on this box I'd just go
ahead and do it via the GUI. Maybe not the answer you
wanted, but it works for me.
If I don't have an existing bond0, do I simply use same line above but with en0 to create it.
For example: ifconfig bond0 bonddev en0
And is there anything else that would require tweaking after the bond is setup.

Use of two ethernet ports?

My 5 year old Mac Pro is noticeably slower downloading data over the net than is my 1 year old Mac Book Pro, even when they are conntected to the same switch in my home. I know of some systems where two links to the internet can be combined to gain greater throughput. Will the Mac Pro do this?
Adam

two links to the internet can be combined to gain greater throughput
Yes, it literally can, but it requires a specialty Router that supports the feature.
For all practical purposes, except in data center use, the answer is NO.
But that is not the answer at all. Most Internet connections are very slow compared to the Gigabit Ethernet of which your Mac Pro is capable. The connection to the Internet is not likely to be the problem.
First, use Network Utility to check the actual speed of your Ethernet port, and that the Ethernet port is the port being actually used, and that the number of errors reported is extremely trivial and not increasing over time.

Problem with two ethernet ports?

There is little consistency to this, but I'm wondering if anyone else has a similar problem. I upgraded to 10.6 on my Mac Pro. I have two ethernet connections which run concurrently in my network setup - one internally addressed, using a manual IP with DHCP, the other an external address with a static IP. On an inconsistent basis, opening pages in Safari will result in failures because I am apparently not connected to the internet, despite the fact that I am - Mail continues to work fine, server connections remain, etc., etc. The only way to get Safari to work again is to disable one of the ethernet ports. Reenabling it after I have successfully made a Safari connection does not then break the connection again - it keeps running for quite a while. The problem seems to become more apparent when I open a selected group of links into tabs - some will be successful, most will fail. Ideas?

Snoop Dogg thanks for the reply.
Port ONE was set to auto DNS. I did exactly as you suggested, I even tried a to do a manual ip address, etc but no luck. What finally worked is, I moved the port one cable to port two (which was empty) and bingo it worked.
It seems that snow leopard may have some issues with dual ethernet port machines, but why port two worked and port one didn't is beyond me. I will try to reverse it back to port one and see what happens. Fortunately I don't need two port at this point.
Cheers, Terry.

Two Ethernet-ports in Quad G5

Hello all,
each of the two built in Ethernet-ports works fine as long as I only use this one.
But if I try to use both at the same time (half of the net connected to each of them; each to one switch; separat IP-numbers for each one), the whole net does not work for me anymore.
What goes wrong here?
Will I have to use another subnet-mask for the second port?
What is the trick?
Any help would be welcome.
Thanks,
Hans

So are you good to go?
The following is subject to correction by anyone who knows better.
From what I understand....
The subnet mask is intended to tell the TCP layer what part of the TCP/IP address the driver level should process. In the case of the standard setting 255.255.255.0, the driver only looks at packets that have the same configuration of the 24 most significant bit of the address. The 24 bits is indicated by the 255.255.255. The "255" is the decimal equivalent of an 8 bit pattern where all of the bits are set.
The mask is intended as a way of pre-screening packets.
So looking at your address indicates that a mask of 255.255.254.0 is only screen the top 23 bits of the address. Since 10.21.58 differs from 10.21.4.242 in the third 8 bit sub-address in bits 6,5,4,3,1 (zero based) a subnet of 255.255.X.0 where X = 192 193 or 0 would work.
All of the above is based on my very old recollection of how the subnet mask was to be used. I can not be certain this is correct and if switch gear supports masks other than 255.255.255.0.
Just trying to help,
Ben

[Solved] Two ethernet ports (dhcp and static)

For various reasons I connect to the internet as follows:
Computer --> eth0 --> Linksys Router --> Aztech Modem/Router --> Internet
From time to time I need to access the Aztech. Usually I change the eth0 cable connecting to the Linksys to the Aztech. And restart networking. Access the Aztech. Then change the cable from Aztech to Linksys. Restart network.
In Debian (to avoid this cable changing), what I did was to also have a cable as follows:
Computer --> eth1 --> Aztech Modem/Router
eth1 is a static configuration. The debian /etc/network/interfaces file looks like
auto eth0
iface eth0 inet dhcp
auto eth1
iface eth1 inet static
address 10.0.0.3
netmask 255.255.255.0
So in Debian I plug a cable into eth1 (from the Aztech). I can then access the Aztech without it interfering with resolv.conf so I can still browse the internet via eth0.
I have tried the following in ArchLinux:
HOSTNAME="milomak-arch"
eth0="dhcp"
INTERFACES=(eth0)
eth1="eth1 10.0.0.1 netmask 255.255.255.0"
INTERFACES=(eth1)
gateway="default gw 192.168.1.1 10.0.02"
ROUTES=(!gateway)
However when I boot this is what I see
# ifconfig
eth1 Link encap:Ethernet HWaddr 00:24:8C:52:DC:5F
inet addr:10.0.0.1 Bcast:10.0.0.255 Mask:255.255.255.0

what am i missing?

Put both interfaces in the INTERFACES= array.
/etc/rc.conf includes this detail, with a slightly different wording i.e.
# Interfaces to start at boot-up (in this order)
# Declare each interface then list in INTERFACES

Serversetup -sethostname with two ethernet ports

I have added a 4 port gigabit card with link aggregate to the headnode of our cluster. I have set up this aggregate port on a second subnet (192.168.2.1). I have the nodes resolving to my head node through their second port to this gigabit card. I can ssh into either port now on any given node (e.g., en0 and en1).
For each node, I have the hostname for the first port (en0) set as nodexx.cluster.private and for the second port (en1), which I've just added, pnodexx.cluster.private. When I ssh into the node via en0 I get the prompt:
node02:~ admin$
When I ssh to the node via en1, I get the prompt:
node02:~ admin$
But I would expect to get:
pnode02:~ admin$
I was going to ssh into the node through en1 and do a serversetup -sethostname pnode02 but I'm afraid this will reset the hostname for en0, which I do not want to screw with.
Will this work as expected if I do the serversetup -sethostname?

Your machine will only have one hostname, regardless of the number of interfaces it has. If you try to change the hostname to pnode2, that's what it will be.

Looking for an Access Point with 2 Ethernet ports

Hi,
I am looking for an AP with two ethernet ports. Is there any model of Cisco is available with 2 ethernet ports?
Regards,
Noman

pros:
If an access swich/switch port failed then AP still forward traffic through other switch once power restored through other port.
when PoE failed on its connected switch, it may still work via other port.
Having two ethernet port on AP may require to talk to different switches/stack to achieve AP port redundancy through lag or stateful switch over when cable/switch/AP port failure.
if one physical port become bad on AP, it can be still used with other.
(However, AP/physical port failure can be takencare at RF level using self healing.)
cons:
require additional switch and its config maintanece
currently, AP doesn't require 2 physical port for data transfer perspective.
Require x2 PoE ports.
Additional port increases the cost on AP.
it is possible cisco may make it in future.

How to add Ethernet ports to an Airport Extreme Base Station?

I have successfully connected an HP Office Jet 6310 to the Airport Extreme Base Station, after downloading the latest software from HP. It is printing wirelessly, and it is great so far.
The only problem is that the cable modem connected to ADSL has only one Ethernet port, and the Airport Extreme Base Station also has one Ethernet port. However, I need one more port to connect a phone (Vonage Telephone Adapter = VTA).
What is the easiest way to achieve this? I saw several other messages discussing hubs and routers, but the answer is not clear yet. If I purchase an additional router, should it be connected between the cable modem and the Airport Extreme Base Station, or the other way round?
Any help or advice would be appreciated!
Thank you in advance for your time.
MacBook Pro with 1.83 GHz Intel Core Duo Mac OS X (10.4.7)

One final vital piece of information, which should be my conclusion on this topic.
Following the advice received, I purchased a Switch from Linksys. Since the device didn't work for my purpose (dividing the Ethernet connexion into an Ethernet line for the HP printer and the Vonage phone), I called the Linksys support.
I was told that what I needed was not a switch, but a router. I thus had to get reimbursed for the switch and hunt for the proper router.
Finally, today, I have been able to find the item corresponding to my needs:
A Belkin Wireless G Router F5D7230-4
It costs less than 50 US$ and has all the necessary Ethernet ports. The setup is very simple, and I got it operational within a couple of minutes, despite some small problems getting the setup Wizard to work. It is Mac OS X compatible.
Thus, at the end, I have got the HP 6310 Office printer and the Vonage VTA phone working together, with a robust Wireless network including WPA security. I would recommend this type of setting.
The only trouble is that the AirMac Extreme Base Station has become completely useless! I will perhaps keep it as a souvenir, or as a decoration in the living room... This wouldn't have happened if the creators of this nice object, which is extremely expensive for what it provides, would have thought of including at least two Ethernet ports!
The unexpected reply to my query could thus be ironically formulated by saying: "replace the Airport Extreme Base Station with a cheaper an more efficient device." Sorry for that!
With my best regards to those who took the trouble to read this thread to the end.
Yours, Hotaru

How do you make use of the 2nd Ethernet port on the Mac Pro?

My Mac Pro's ethernet port connects it to the local network and the internet.
Under what circumstances would I make use of the 2nd port?
Are there any settings I'd have to set up in system preferences to make sure one is used for some things while the other is used for different things?
I'm asking because we might be making some changes to our network. We have a printer with a Fiery RIP and I'm pretty much the only one who prints to it. I was wondering if we could/should set up a direct, dedicated connection so that network traffic won't bog down print jobs.

The main use for that port today is to create a subnetwork for Internet Sharing. Software inside the Mac can act as a Router and provides new DHCP Addresses for the subnetwork. In general, the devices on the subnetwork would be inaccessible from anywhere else, due to Network Address Translation.
If you are concerned about heavy network traffic, consider upgrading your Switches (not Routers) to Gigabit Ethernet speeds and using Jumbo frames. (Routers are not involved in peer-to-peer transfers such as Printing when no Address Translation is involved.)
If you have an Industrial Router, you can combine the two Ethernet ports into one composite link for faster-than-Gigabit effective speeds, but it requires a special Router not generally available.

Maximum Number of NICs and Ethernet Ports

Dear Friend,
I am looking into constructing a Sun system with the maximum number of ethernet ports.
Q1: is there a Solaris 8 specific maximum number of ethernet ports that it can support?
Q2: i know you can get quad ethernet cards, but anyone know of cards that offer more than four per card?
Q3: assuming the cards will be PCI, which sun machine offers the maximum number of PCI slots?
I really appreciate your help
many thanks
wagwan

Hi Rukbat
Thanks for your response.
> A1: There isn't any limitation within the OS.
> Your limitations are from the hardware of the system.
Indeed, I did not think there would be a limit from within the OS. I have had a research sun machine with some 12+1 ports, an ol'Ultra-10 actually. i got upto that many ports by using three qfe's and there is one port already on the system (hme0)
>If you have too much packet traffic for your cpu modules
> and RAM, you'll have delays, data corruption, or even
> system panics.
one accepts that there would be delays - naturally. but I am not sure why there would be data corruption or even panics. that to me sounds very very serious.
the ultra-10 seems to be working ok; I never saw it crash once. But I must confess that the traffic load is not THAT high.
> Long time ago, there was a general rule-of-thumb
> for the QFE cards:
> -- one cpu per TWO ethernet ports,

erm erm I would say that is pretty low, but I would not call myself an expert on this really.
> I'm sure there is a similar suggestion for QGE's and fast
> cpu's in this 21st century.
i would like to think that one modern cpu should be ok for about 10 ports with reasonable traffic load. I am judging this by the old Ultra-10 I have built, beside which I have no supporting evidence.
> A2: There are no Sun-qualified adapters with more than
> four ports per card.
i am surprised at that.
> Third party hardware? you'd be on your own and need

yes I agree
> Besides, there is only so much room on the card's

I take your point about the physical space on the backplate. I have found one company that is knocking up 6-port devices, and from what I gather, that is as much as one is gonna get.

that is a good hint actually. that is the high-end range I think.
in any case, I think the sort of machine I would be looking for is in sun's mid-range of servers. something like a V440, which has 6 PCI slots for use. I could potentially have (6x6)+2=38 ports. It is also capable of taking four 1.593-GHz UltraSPARC IIIi processors, and my gut feeling is that the four processors will be ok to support 38 ports.
I am still open to take advice of course. Indeed I would very much appreaciate further thoughts!

Is my right Ethernet Port Broken?

05Apr2014
I bought a new Mac Pro with all the features. There are two Ethernet ports on the bottom of the periferal ports.
I am able to connect with an Airport Extreme (Generation 3) wiht the left port. The connection does not work on the right ethernet port.
Is the right ethernet port broken? I only had the computer for a few weeks.
Also, I can not see the Airport Extreme (Gen 3, March 2009) when I use the Airport Utility.   Is that model of Airport Extreme compatible wiht the new late 2013 Mac Pros?
I prior to getting the new Mac Pro, I had a 2007 Imac connected to a mac laptop.   I had both computers connected to the Airport Extreme using ethernet cables.
Now I use the Imac connected wirelessly to the Airport Extreme and the same laptop plus the mac pro are connected using ethernet cable. However, I can connect the Imac and laptop like before, but I can not connect any computer wiht the Mac Pro.
I also installed McAfee Internet Security sotware which maybe causing my connection problems.
I configured the network years ago and forgot how to connect computers together.
Does the right side ethernet port need to be repaired?   Is the Airport Uthility software compataible with new Mac Pro?
I'd appreciate any help wth these issues.

RE: The two ethernet ports:
     I only need one port. It is connected to an Airport Extreme (which has a laptop connected with an ethernet cable).
     The port on the right is closer to the Airport Extreme, but it does not work.   This is meerly a frustration that a port to a brand new machine (Mac Pro).
      I get the internet. I have a cable modem connected via ethernet cable to the Airport Extreme.    I have a Imac connected by WYFI and the laptop and Mac Pro conneced to two of the ethernet ports of the Airport Extreme.
      My next goal is to network the three computers, which I used to be able to do. I have a Airport Dock, connected to a DVD player and two Tivo boxes. I lost the connctivity of the Airport Dock, so my Tivoes are not working right.
       Yesterday was a frustrating day! I am certainly not a trained network manager.   I don't know what I did to loose the connections and I compleltly forgotten how to get the connectivity back.
Thank you for your help!   I want my brand new Mac Pro to work perfectly!   I forgot how furstraiting it was years ago to confiigure computers.

Setting up 2nd Ethernet port for NAS connection

Hi
I want to split out my internet and NAS drive access across my two Ethernet ports.
Port 1 is connected to my router and connects to the internet.
Port 2 is connected to a gigabit switch and then into two NAS drives. I have set up the second ethernet port with a manual ip and it says it is connected. But when I use Command K to connect to the ip address of the NAS, it cannot connect. Previously this worked fine when everything was going out of Ethernet port 1.
I suspect I have not set up Ethernet port 2 correctly. So far I have set it up for manual configuration and given it an ip address of 192.168.1.17 (the NAS is 192.168.1.18, Ethernet 1 is 192.168.119). Nothing else has been entered.
Any advice gratefully received. Thanks

Ping the destination address 192.168.1.19 from a terminal window and see if it responds.

No modem port but 2 of RJ-45 Ethernet ports?????

I have MAc Pro Dual Core Intel Xeon, I dont have a modem port is that normal but I have 2 of RJ-45 Ethernet ports, why do I need 2 and what is 2nd RJ-45 Ethernet for, can anyone explain this, thank you very much.

You can buy a Modem if you want one. Apple decided that very few Mac Pro users wanted a Modem, so they dropped it from the standard Hardware. Today, you would probably add a USB modem, if needed.
Two Ethernet ports gives you great flexibility. It can allow you to connect to the internet on one, and to a Storage Area Network (shared Drive Farm) on the other. It can allow you to use the two ports together as a team when connecting to special high-speed networking gear and run at twice Gigabit speeds (this is not for "regular" home or office use). Or it can allow you to extend your Internet connection over the other port to another computer.
