WAN MPLS with IS-IS - 1G or 10G ethernet

Which method would be better: use one 10G link, or combine multiple 1G interfaces?
Does anyone know about any pros or cons in using each method?
Thank you very much.

With 10G link, you dont need to worry about load-sharing across multiple links but with multiple 1G links, you will have to see if your links are being properly utilized.
The load-balancing on Cisco platform is flow based, so based on a flow, the outgoing interface will be chosen and traffic will be sent out, so there is a high possibility that a link might be under-utilized. But at the same time the other benefit is, if one link goes down, others are present which is not an option with single 10G link (unless you have couple of them).
From the troubleshooting and manageability stand-point, a single 10G link will be a better option.
There are multiple pros n cons for both the options. At the end, it all depends on the business requirements.
Hope this helps.

Port groups in NX7000 F2 48-port 1G/10G Ethernet module in regard to VDC?

Have couple of questions about assigning ports on the F2 1G/10G Ethernet module to VDC. Thanks for any help.
1) The older 32-port 10G Ethernet module has port groups. When assigning ports to VDC, ports in the same port group should be assigned to the same VDC. Is it the same scenario with the newer F2 1G/10G Ethernet module? If so, where can I find information about mapping between ports and port groups?
2) The older 32-port 10G module has ports in dedicated mode or shared mode due to its 80G bandwidth to the switching fabrid. Is each port of the newer F2 10G module at 10G line rate? If that's the case, I can then assigned any ports to be vPC peer link, as oppsed to the older 32 port module where only one port from a port group can be in dedicated mode to be vPC peer link.
Thanks again

1) F2 has the same limitation. The port-group is grouped by the SoC. Meaning 1-4 is port-group 1, 5-8 is port-group 2, etc.
2) F2 is line rate if you have 5x Fab-2 module. Yes you can assign any port as vPC peer-link but you should consider the MAC limitation when designing such solution.

Want attach the XML data file with layout template in Oracle 10g

Hi All,
I need a help from you genius guys.
I am genrating reports in BI with xml the procedure which I am following is as below.
1. generating XML from the RDF
2. creating a template in .rtf format
3.after that loading the xml to the template then getting the required report.
This all is doing through the given buttons
But now my requirement is to create the gui from user can select the report and get the desire output file so how we would be able to attach the XML data file with layout template in Oracle 10g.
If you require more detail please let me knnow.
Thanks,
Harry

I am not using Oracle apps.
I am using oracle 10g reports and I get something in it like one patch I downloded and one java code is having which creates the batch file ...still I am working on it ..
If you will get some please share so that it will be helpful.

Problem with PJC (Print Dialog) - Forms 10g

I have a problem with my PJC for Forms 10g r2. When I try to connect and run my PJC (raise Print dialog and put printer name in some text item) I get following message:
oracle.forms.net.ConnectionException: Forms session <2> aborted: unable to communicate with runtime process.
     at oracle.forms.net.ConnectionException.createConnectionException(Unknown Source)

     at java.io.DataOutputStream.flush(Unknown Source)
     at oracle.forms.net.StreamMessageWriter.run(Unknown Source)
When I started application, on Java console I saw this message, so I think the server configuration is fine (I change everything I need in Default.env and FormsWeb.cfg files):
Loading http://devsrv/forms/java/jESPrintDialog.jar from JAR cache
What can I change with server configuration or deploying my project to this PJC can work normaly?
Thanks....

Hi and thanks!
I resolve one part of my problem. Tt was about diferent compiler (in JDeveloper 10.1.3 compiler is 1.5 and in my oc4j server JRE is earlier version, so it can`t work normaly).
I comiled PJC in 1.4 version of compiler and now I can start and run my PJC.
But, there is another problem:
this is my part of java code (note: everything work fine except one line when I want to get printer name from select printer dialog):
try {
boolean b;
PrinterJob job = PrinterJob.getPrinterJob();
b = job.printDialog();
try {
return job.getPrintService().getName();
catch (Exception e) {
System.out.println("Error: "+e.getMessage());
return "My error:";
} catch (Exception e) {
System.out.println("ERROR: " + e.getMessage());
return "Problem with PJC [esoft]";
So, when pjc want to get back printer name
return job.getPrintService().getName();
i get following error (on Java console):

Apple Airport Express Base Station 10/100BASE-T Ethernet WAN port with AirT

Hello fellow mac users, I am currently interested in getting the Apple Airport Express Base Station 10/100BASE-T Ethernet WAN port with AirTunes. However I already have a Linksys Wireless G with SpeedBooster router. Will the Airport Express with iTunes work with my router? Or will it work with any router? Thanks!
P.S. I want to get the Apple Airport Express Base Station 10/100BASE-T Ethernet WAN port with AirTunes
Powerbook G4 Mac OS X (10.4.5)

Yes, it should be possible. Since your iMac is connected via Ethernet to another router, you would have to reconfigure which Network Service you will be using on the iMac to switch between streaming and connecting to the Internet.
For example, I am assuming that the Built-in Ethernet service is currently at the top of the Port Configurations 0list within System Preferences > Network > Show = Network Port Configurations when your iMac is connected to the other router by Ethernet. You would then need to drag the AirPort item to the top of the list, and then, connect to the AirPort Express to stream.
The other option to avoid this is to configure the AirPort Express to join the wireless network created by the 2Wire router.

Configuring WAN Simulator with WAAS

Hi all,
I have a remote site in Pune India and I am trying to set up a WAN simulator to simulate the WAN link with WAAS to Pune. Below is the topology and questions.
Server farm <-- WAN simulator PC --> 3750 layer 3 switch <-- client PCs
Questions:
1 - Where would I place the WAAS device ?
2 - I only have one spare WAE for this test. Can this scenario work with only one WAE ? or do I need two WAEs (one on each side) for WAAS to work ?
3 - Do I need a Central Controller for WAAS to function ?
Thanks in advance !!! I appreciate any inputs / suggestions !!
Danny

Hi Danny,
On the second WAE, you need to configure WCCP just like its configured on first WAE. And WCCP will
redirect traffic to both of these WAE's.
There are Two Algorithms for redirecting traffic,
- Hash
- Mask
WCCP intercepted traffic is forwarded to WAE based on bucket placement algorithm, hashing or masking with
IP addresses.
This link explains on wccp redirection,
http://www.cisco.com/en/US/docs/solutions/Enterprise/Data_Center/WAASDC11.html#wp95583
Attached pdf file explains in detail on wccp and redirection methods,
Hope this helps,

Rahul

NX7K VDC: port groups in F2 48-port 1G/10G Ethernet module?

Have couple of questions about assigning ports on the F2 1G/10G Ethernet module to VDC. Thanks for any help.
1) Does the newer F2 1G/10G 48-port Ethernet module have port groups as the older 32-port 10G Ethernet module? If so, where can I find information about mapping between ports and port groups?
2) The older 32-port 10G module has ports in dedicated mode or shared mode due to its 80G bandwidth to the switching fabrid. Is each port of the newer F2 10G module at 10G line rate or still the same as the older 32-port module? I want to make sure the 10G ports for vPC peer link are in line rate.
Thanks again

Hi there
The F2 line card use the SOC (Switch On Chip) architecture where each SOC manages a group of 4 contiguous ports called “Port-Group”
the port groups on the F2 are broken up into groups of four, 1, 2, 3, 4 are part of port-group1, and then so on down the line in groups of 12 groups
"12x4= 48 ports "
For changing the bandwidth and VDC allocation it is highly recommended to use the entire port group using same attribute/VDC
“N7K-F248 Requires allocation in port groups of four to align ASIC resources”
http://www.cisco.com/en/US/docs/switches/datacenter/sw/nx-os/virtual_device_context/configuration/guide/vdc_mgmt.html#wp1170127
the each interface of the F2 is a "10G line rate" which can provide you with up to 480G per line card
however you need to make sure that you have enough Fabric moduls to support the required bandwidth in the backbend/fabric
for example example each FAB2 can provide up to 110G per slot so to run the F2 with its full capacity you need 5x FAB2
hope this helps

I have a Airport network at home with a Time capsule connected via ethernet cable to modem. Also the network is extended wirelessley with an Airport Extreme. I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme. Can my network operate properly to extend the network with both a wireless and wired extend functionallity?

I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme.
Excellent plan.
Can my network operate properly to extend the network with both a wireless and wired extend functionallity?
Yes, but don't get confused about the second AirPort Extreme, as it would not be configured to "extend" a wireless network.....it would be configured to "create a wireless network" using the same wireless network name, security settings and password as the Time Capsule network. Configure the second Extreme in Bridge Mode.
This Apple support document will show you how to hookup and configure the second AirPort Extreme:

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.

10G-Ethernet RJ45 (10GBASE-T) and direct attached SFP+ Twinax (10GBASE-CR)?

Hello,
I'm searching a switch that does support 10G-Ethernet RJ45 (10GBASE-T) and direct attached SFP+ Twinax (10GBASE-CR).
I do not have big requirements, but it should be as cheap as possible.

Would like to connect an SFP+ port to 10GBASE-T port?
Maybe a media converter is enough for your demand.

10G Ethernet and FCoE ports - Whats the diff?

Hi All,
I know what FCoE is and all that stuff. My only confusion is when we say that Nexus 5K ports can be configured either as 10G Ethernet or FCoE ports, what that actually means? All Cisco video data sheets say this.
I know Nexus 5K supports FCoE as a switch. But, why would they say the ports can be configured as FCoE? If a physical port supports Ethernet, then it must also support FCoE frames, right? After all, FCoE frames are Ethernet frames carring is just another payload type (FC, EthType = 8906). So, for Ethernet, FCOE frames are just like any other traffic. What is special about a port being said as FCOE enabled port?
My own answer to is this. If the port is FCOE capable, it will look into the incoming frames and if Ethtype is 8906, it will forward to the FC part of the N5K. If any other EthType, forward it the LAN side of the N5K. Is this corret?
Also, if an Ethernet Switch is DCB capable, that is, CEE, do we call this as FCoE Switch? This switch is not going to open the Ethernet frames.
Looks like these definitions are not clear...
Would appreciate any help in clarifying this.
Thanks and Regards,
Mohan

Hello Mohan,
In the Nexus switch when you bind a virtual FC port to a physical port, the switch knows that port will now process FCoE frames.
For the Nexus switch is pretty simple to identify a FCoE frame from another frame, just looking the Ethertype as you said.
When a frame comes in the switch port, the asic checks the ethertype of the frame, if a 0x8914 (FIP) or 0x8906 (DATA) ethertype match, then this frame will be processed by the SAN built in switch.
The DCB is the correct term, using by IEEE. The CEE as far I know is a IBM terminology that supposed have te same features of DCB. To be correct look for DCB capability and you will know that device can support FCoE.
Lastly, be aware, just because the box is "DCB capable", it not means have FCoE implemented. The DCB is just a requirement to you run FCoE in your product.

Richard
