Cisco WAN :: 881 - Generate Test Traffic From Router?
Dec 8, 2010
I have configured an Cisco 881 router in our lab with netflow commands and pointed to our network monitoring tool and I want to check if the tool can collect valid traffic statistics from this router (eg. utilization). The problem this router has nothing plugged into a production LAN that would potentially generate traffic to measure using this tool.
Is there a way to configure a Cisco router (ex. Cisco 881 router) to artificially generate network traffic to test that I have setup the monitoring tool correct to capture future utilization statistics?

As of late, I've been pretty unsatisfied with my WRT54GV6 with DD-WRT. It just can't handle the amount of traffic that my network generates now. I was considering building an Untangle or pfsense box and wanted to know if drivers or performance were an issue.

Attached setup i am planning for testing multicast output from different vendors using VLC and STB. This Setup made to test the picture quality between the vendors at the same time on the multi viewer screen.
1) Only a 2960 Gig port switch with only one L2 v lan with IGMP snooping enabled.
In this scenario where Source and receivers are in the same L2 v lan ( no L3 interface is involved) hope i would able to test all the multicast sources with out any additional configuration on the Cisco switch.

I have two 1841's, setting up a Lab WAN in Packet Tracer. I have one of the 1841's run to a DSL modem, then out to the cloud and the same setup on the other end... from the cloud to the DSL modem and to the 1841 on that end... I have all green lights, so that tells me layer 2 is up, but I'm trying to figure out
what IP to assign the routers to test pinging and getting traffic flowing. but the DSL Modem's have the public IP's and dynamically assign an IP to the routers? I've also tried setting up a static IP on the routers fa0/0 interfaces and the pings fail.. Wondering what I am missing to get these two talking.

Question re: DIR-655; Hardware ver A4; Firmware version 1.32NA
During bandwidth tests to several sites (principally speedtest.net) I get ping times of 10-11 ms, download speeds of 12+ to 17+ mbps but failure on upload tests using my DIR-655.
When I bypass the 655 and test directly with my cable modem, all (including upload) tests work reliably and consistently.
I have swapped the two ethernet cables involved as well as replacing both with new cables but the results are the same (uploads fail with 655 and work without it)
I have seen several postings over the the last year with this same problem but have never seen any comment from D-Link, or a solution from any reader.
Not that it should have any bearing, but I have TA785GE-128M motherboard and am running Windows 7 (patch current) on COMCAST
is this problem acknowledged by D-Link and is there a solution?

Is it possible to generate a public RSA key of 4096-bits on an IOS router? We are running 12.4(24)T5. Have been going through some cisco doc and found this:
Cisco IOS 4096-Bit Public Key Support in IOS 12.4(11) and later.
However when I issue the command,crypto ca trustpoint exampleCAkeys, rsakeypair exampleCAkeys ?
it only shows me the maximum of 2048. Am I missing something? Currently our root cert has a public key of 2048 and the routers a key of 1024. The goal is to increase the root cert and our routers cert to 4096-bits. If that's possible.

I'm getting below msgs in my ZBFW logs on my test router. .Apr 2 23:09:43: %FW-6-DROP_PKT: Dropping icmp session 115.186.192.153:0 10.40.2.100:0 on zone-pair ZP-OUTSIDE-INSIDE class class-default due to DROP action found in policy-map with ip ident 0
The bit I'm curious about is that I am NOT NAT-ting any ICMP. Hence why is the ZBFW even triggering against the LAN IP? It should only activate after NAT according to order of operations (and hence why unlike CBAC you put the inside local IP not the outside global IP).....
If the ICMP was directed at the WAN interface (not the 10.40.2.100 internal IP) then it is allowed, but morever even if blocked it should be logged against my WAN IP (which is publicly routable not a 10.x internal).

We are already having a True business ID certificate from Geotrust for our SSL VPN on CISCO ASA 5510.this is working fine.
We are now changing our device from ASA 5510 to ASA5520 in failover setup. As we check with Geotrust they are asking us to create a new CSR with same parameters from new ASA5520 device and reissue the certificate from their site.In this context how to create a new CSR from ASA5520 8.2(5). create CSR from ASA 5520 8.2(5)

I currently have a 802.11 G router of 54mbps (its claims its a super G 108 mbps tough). My notebooks have 802.11 N built in. Im thinking of upgrading my router to a 802.11 N 300mbps.However, I know that this may be irrelevant unless I have a internet conection that can achieve such speeds. So how do I test my internet speed to see if G is bottlenecking?

I am trying to create a Script to reload my cisco 1941 router when a ping test has failed.I am using IP SLA to ping and tracking snmp oid. What I want to do is to stop the router from reloading after 4 times if the ping test is still failing . But when the ping are successful again to restart the applet. I have the reload configured but cannot figure out how to do the rest. [code]

I am running CiscoWorks LMS 4.0.1 since 6 months and I wanted to generate today a report about the interface utilization on 2 Cisco switches (Catalyst 3750G). The corresponding job is created, it runs and then i get "succeeded with info" in the "Run Status" column. When I want to click then on the "View Report" link, I get the following error: "Could not generate the report. Either data is not available for the specified duration or the report job failed."
I tried the same procedure with 2 other switches but I have got the same result.

Have a localhost site to test PayPal IPN which apparently requires router configuration to use port forwarding (or redirection) to send TCP traffic on public port 80 to my test machines private IP at a specified port.
A typical configuration might look like this:
Router NAT Port Redirection Rule TCP Public Port 80 --> 192.168.1.2 (Port 8888)
Where can I find reference to this in online documentation and where do I put this instruction?

I did a simple speed test comparing my EA3500 and Linksys WRT54GL. I used DSL Reports for the test. I was quite shocked and am wondering if the difference is due to the poor wireless driver in the Classic firmware that was updated in the Cloud firmware. Here are my numbers: EA3500, Classic firmware Download average 475 kb/s Upload average 725 kb/sLinksys WRT54GL Ver 1.1 (latest firmware) Download average 3250 kb/s Upload 725 kb/s
Needless to say I have gone back to my trusty WRT54GL until Cisco decides if it will update the Classic firmware and give us 2nd class Cisco customers the same hardware the 1st class Cloud customers have. Time will tell.

I installed an E1200 router today. It automatically upgraded the firmware to the latest when I did this. Everything went smoothly.
I connected my desktop wired and my laptop wireless. I ran three different speed tests: Xfinity, speedtest, and cnet. All three showed 25-35 Mbps download and 4-5 Mbps upload. That is what my old router had too. So far, so good.
I ran the speed test that came with the E1200 router. It showed 0.30- 0.66 Mbps download and 0.58 - 2.09 Mbps upload. Note the decimal points!
Bottom line: The E1200 seems to be working fine, except that its internal speed test seems to be broken, at least when testing from a wired machine.

we have a policy on ACS to disable user account (Internal user identify store) after X days if password is not changed. However, a few days before the password expires, there is no notification for users unless he happens to log in IOS router (tacacs) through console. in other words, if he logs into IOS devices through VTY, there is no notification at all.some users got locked out becuase they were not notified to change password. What setting on ACS 5.2 must be configured to display warning on VTY before password expires?

I have a WCS server running the version 6.0.170.0. I have already added few WLCs running the version 7.0 to this WCS. It is working fine. And now I have added two new controllers running the version 7.0.98.0 to the existing WCS server. When i add the floor layouts to the WCS and position the access points from the new controllers, the heat map is not generated automatically.

what's the meaning of the output:
Interface Speed Local pair Pair length Remote pair Pair status
--------- ----- ---------- ------------------ ----------- --------------------
Gi0/40 100M Pair A 2 +/- 4 meters Pair A Normal
Pair B 2 +/- 4 meters Pair B Normal
Pair C 2 +/- 4 meters Pair C Short
Pair D 2 +/- 4 meters Pair D Short
From the command
test cable-diagnostics tdr int gi 0/40
It's normal?If not, then. the problem is on the cable or on one of the interfaces?The interface is connected between a fastethenert on a 2811 router and a 3560-48 switch.The cable is a straight through cat 5e cable. (I have changed several cables with same result).

Basically i need to test to see where the telephone lines are terminated, because when they where built into the walls the used standard cat5e cable to terminate it to an RJ-11 jack but over in the wiring panel it (i assume it is anyways) terminates to an RJ-45 jack but im not sure if this is really the cable for the telephone or something else, so i have a phone connected to the wall jack and a computer on this end and i would like to send a dial tone or any tone in general that the phone can pickup.

I have a TP-Link Wireless Router (TL-WR340G) and I use it for both Wired and Wireless connection. I have two desktops that connects to the router through cables and I also have 2 notebooks that connects through WiFi.
Now, I want to know if there is any software that can generate passwords which I can assign into individual PCs that connects with Wifi. For example, Notebook #1 has the password "abcdefghij" and the Notebook #2 has the password "1234567890" and they can both connect to the WLAN.

I upgraded 3 days ago from a (WRT160N ver. 1) to a (E3200) After setting it up and syncing all the devices including the XBOX 360. After signing into Live I noticed that every time I power off and power on the console it's IP address would change causing the NAT to become moderate so I went over to the Xbox360 open the Network settings and Manually set the IP address Mac address, Gateway address. Then I opened the routers settings page and Port Forwarded the correct ranges also copied the IP address I manually entered earlier on the Xbox 360. On the router side I saved the changes restarted the console and my NAT was open, but here's the Issue now when I go to sign into Live I get a pop up saying I can't connect to Live to "Test the Connection". After I "Test the Connection" then and only then I can sign into Live.
