For Command Line, specify "format" under the options -o. Example Syntax: osfmount -a -t vm -m "F:" -o format -s 1G. This includes support for Dynamic-size or sparse hard disk images. Differential images are not supported. Support was added via libvhdi.
This includes attempting to mount all partitions from an image file as individual drives. AFD, E By default without this option , TRex waits for all flows to terminate gracefully. In case of a very long flow, termination might prolong.
Prevents TRex from changing flow control. By default without this option , TRex disables flow control at startup for all cards, except for the Intel XL 40G card. Relevant only for Intel x stateless mode. Do not use HW counters for flow stats. Enabling this will support lower traffic rate, but will also report RX byte count statistics. Send all packets of the same flow from the same direction.
For each flow, TRex will randomly choose between client port and server port, and send all the packets from this port. Meaning, we get on the same port packets from client to server, and from server to client. If you are using this with a router, you can not relay on routing rules to pass traffic to TRex, you must configure policy based routes to pass all traffic from one DUT port to the other.
Platform factor. If the setup includes splitter, you can multiply all statistic number displayed by TRex by this factor, so that they will match the DUT counters. Enable Rx check module. Note: This feature works on the RX thread. Use sleeps instead of busy wait in scheduler less accurate, more power saving.
Do not configure any hardware rules. In this mode, all RX packets will be processed by software. No HW assist for dropping while counting packets will be used.
This mode is good for enabling features like per stream statistics , and latency , support packet types, not supported by HW flow director rules For example QinQ.
You can also use this mode for running TRex on interfaces which manifest themselves as ones supported by TRex, but in reality support less hardware capabilities. Drawback of this is that because software has to handle all received packets, total rate of RX streams is significantly lower. Up until v2. Now it uses multi-queue for RX and TX mainly for scale of virtual interfaces. Show debug info.
Value of 1 shows debug info on startup. Value of 3, shows debug info during run at some cases. Might slow down operation. When configuring flow stat and latency per stream rules, assume all streams uses VLAN. Wait additional time between NICs initialization and sending traffic. Can be useful if DUT needs extra setup time. Default is 1 second. Fedora 21 Server installation. Table of Contents. Introduction 1. A word on traffic generators Traditionally, routers have been tested using commercial traffic generators, while performance typically has been measured using packets per second PPS metrics.
Accurate performance metrics. Discovering bottlenecks in realistic traffic scenarios. Current Challenges: Cost : Commercial stateful traffic generators are very expensive. Scale : Bandwidth does not scale up well with feature complexity. Implications High capital expenditure capex spent by different teams.
Teams use different benchmark methodologies, so results are not standardized. Delays in development and testing due to dependence on testing tool features. Resource and effort investment in developing different ad hoc tools and test methodologies. Stateful traffic generator based on pre-processing and smart replay of real traffic templates.
Generates and amplifies both client- and server-side traffic. Customized functionality can be added. Low cost. Self-contained package that can be easily installed and deployed. Table 1. Download and installation 2. Hardware recommendations TRex is a Linux application, interacting with Linux kernel modules. Table 2. Table 3. Memory 2x4 banks f. Total of 32GB in 8 banks.
Table 4. Memory 2x4 banks for each CPU. Table 5. Table 6. Table 7. Use Silicom with Open Optic. Table 8. Table 9. Table Cisco would be fine with TRex but not for plain Linux driver. Installing OS 2. Supported versions Supported Linux versions:.
Additional OS versions may be supported by compiling the necessary drivers. Obtaining the TRex package Use ssh to connect to the TRex machine and execute the commands described below. Only https is supported. First time Running 3. Identify the ports Use the following command to identify ports.
If you have not run any DPDK applications, the command output shows a list of interfaces bound to the kernel or not bound at all. The interface marked active is the one used by your ssh connection. Never put this interface into TRex config file. Next, edit the configuration file, adding the interface and IP address details. Change according to your setup. Change according to your needs. In case of loopback, you can leave as is. Edit this line to match the interfaces you are using.
For more info, see trex Script for creating config file A script is available to automate the process of tailoring the basic configuration file to your needs. Interactive mode: Script prompts you for parameters. Command line mode: Provide all parameters using command line options.
Interactive mode The script provides a list of available interfaces with interface-related information. Command line mode Run the following command to display a list of all interfaces and interface-related information:. Include enough cores for each NUMA. In special cases, it may be reasonable or advantageous to run TRex on VM:.
If you already have VM installed, and do not require high performance. Before version 2. Click the host machine. Reboot the ESXi to apply. Low-end machines. Enable low-end mode. Set process affinity to this core default is 0. Sleeps in scheduler instead of busy wait less accurate, but saves power Do not retry sending packets in case of queue full.
Tx bps L2 Linux interfaces. Does not require hugepages. Demands more CPU utilization. Slows down the Linux overall. Socket, id and secret needs to be the same for pair of connected memifs , role has to differ.
One of pair needs to have role master and second slave. Emulation stacks. It can be extended in future to: Support other protocols that Linux natively supports Many [thousands] emulated clients, while TRex port is behaving as switch connecting all that clients.
Dummy ports Dummy ports are available to solve 2 issues:. Odd number of interfaces. For example, TRex with only one interface. Performance degradation when adjacent interfaces belong to different NUMAs. Supported in TRex as of v2. Consider the following if using dummy ports for a single interface TRex generator:. When mode 4 is used, more settle time could be needed. I want to fill ITR 2 offline with Prefilled or blank.
Do not have Excel software. I installed the Utility. Schedule Sal shows Rs. Under Schedule other income Intt. After adjusting the deductions the toat lncome amount comes to Rs. The tax as per my calculation on this comes to Rs. Now the total tax comes to Rs. As I have paid excess, I should get refund of Rs. I think the the STCG income has not been deducted from the total income while calculating tax liability.
What I have to do? I have already raised grivances and telephoned the deptt. But to no use. No resolution has been provided to me. Sir, Would you please guide me in this regard, what course of action I should take? Thanks and regards. Lalmohan Patnaik. I am unable to find any relevant section. The main E- filing portal for the AY was a total failure and the return was rejected for defects- viz.
In spite of our many requests to the Income-tax department, we received a blank reply and the status remains non-functional of the new portal. I am not able to register authorized representative. On loading I get the error as the representative pan is different from the main pan of the huf. Please let me knwo if the problem can be resolved Thanks Ramachandran.
Can you please help me with what could be the problem? The ironic part is that the online utility indicates no error on validation. However, this error pops up while verification. I am facing the same problem. Though I have tried to correct the error in the Dividend section. The same goes with yr last part. Hope they rectify if there is an error. Therefore unable to verify and submit ITR.
On Twitter, the dept asks to email issues to orm cpc. Anyone has a solution for the above glitches? When will this portal become glitch-free?
Totally agree. I have filled my ITR, but unable to verify it yet since the month beginning. For me, apart from inputted fields going missing, in spite of entering multiple times, the issue I face is this. First it says no validation errors, proceed to everification.
And when I do that it says one error found and the error is schedule VIA. It says the total does not match with 2u.
This particular schedule takes time to load, becomes unresponsive for a brief time etc. There is only one field where I hv inputted the figure for 80 C.
The total deduction is auto populated and the same amount is appearing in total. I dont know where the difference is as appearing in the message. Multiple grievance raised and no reply. Because the figures goes missing, each time I go through every schedule and proceed.
Lots of time wasted and still not yet completed. Really frustrating. Column B4 does not have any provision to show the above deduction. Whereas space for deduction under sec 54 F which are not relevant, have been given.
I am wondering how to file this online. If a bank account is not validated, the return cannot be filed. If we delete the bank account, then the return filed is not as per compliance laws. Huge huge mountain size problems in Online ITR2. Problems were reported to ITD but no resolution coming. No excel utility being released. Maximum returns will be faulty this year. Sir, Now new income-tax portal has launched so please guide as per new portal also. As you know older one is stopped working.
With allowed deductions, this TDS may qualify for refund requests. Thank you. At the time of validating the IT returns the name of the person signing is greyed out.
There is no option to fill it when it is mentioned self. Kindly guide me in this regard. Sorry for the inconvenience. Further to my previous mail, the SIP is from 1. How to enter the details in the A table. Should I enter 60 rows? LTCG is 41, Madame your other income is treated in a normal way.
If your other income is less than 3 lac no tax. Ltcg first 1 lac is exempted. I live abroad, and I need to file India Income Tax return online. Thank you for your kind help. Is there a way for me to file that now? I do not have any tax due, but i am expected to get a refund. You can file it late as long as you were not having taxable income. However, refund might come a bit late. I have no income from any other source. I do not have any taxable income this FYR I am having income from salary and filing ITR-2 to carry forward current year losses on house property.
My income chargeable under the head salaries is 38L and the loss from house property is 5. Please help. I have a few queries:. I understand that I should have filed ITR -2 instead. I do not have any Indian income apart from a small amount of interest earned on Saving Accounts. There is a flat under my name in which my parents live. I read somewhere earlier that for an NRI it is not mandatory to disclose the overseas income. However, all the income earned in India must be disclosed. Kindly confirm.
I am also not able to enter it manually. Is this a bug with the utility? What do I do? I am able to enter 7 rows in the list.
After that I can also calculate tax for the ITR2 properly. Just before the error message, the specific section A3 of the schedule FA where the problem lies is shown. I have tried reentering the 8th row many times — all with same result. If I delete the 8th row then everything works fine. Has anyone seen this problem? Tried contacting income tax help desk — got disconnected.
Thanks for any help. While finalizing my return at last when a summary is generated after clicking generate XML, there is no schedule of CG and OS in that summary in fact it is there in the tax calculation sheet? In schedule FA, it is not specified which table should be used to declare foreign stock? Screenshots are all blank, perhaps a filled screenshots with dummy data will help more.
This has increased my taxable income. I have not been paid the money but I have to pay tax on that from my pocket. Is there any solution to this problem? I am a senior citizen. Can I file it online?
