I have a Catalyst 3750 router and would like to know if this can be setup to accept communications from a storage switch which uses a fibre path to then send the signal onwards to some test equipment which uses a copper ethernet connection.
View 7 RepliesAt our small business I would like to be able to test connecting to some of our websites as an external IP address user outside of our network although still being physically connected to the internal network. Any thoughts on the simplest way to set this up? I have the capability to setup vlans on our switch, could I make one of the vlans/ports have an external connection instead of an internal?

He have since bought VCE V block for our production sites. we use the franc ken block to test before we migrate to the production v block 300 FIX the issue we have is the 5010 will only see two 1 Gb/s SFP fiber modules in the first 12 slots. All these slots are dual 1g/10G. If we add more than two, it claims not to see them. We tried swapping the sfp and using both sfg-GE-MM and GLC-SX-MM moduels, no difference at all 1g sfp are in the first 5 slots. only the first two slots are up.the others say "Link not connected" or "SFP not inserted"all five links are the same SFP and are plugged in other switches.the green link lights are on plugged in SFP, even when the CLI states they are not plugged uni tried both two types of 1 Gb/s SFP. sfg-GE-MM and GLC-SX-MM ,i move the sfp between slot 1,2 and 3,4,5. nothing changed,From "sh int brief" you can see that it can see the sfp ie they are all 1Gfrom "sh int status " it sees 1g but why does it say type 10G?why when i go to the "int e 1/5" and try switch port mode now, it can't mode and trunk at now there (;also how to i stop or clear EU51 %SYSMGR-2-TMP_DIR_FULL: System temporary directory usage is unexpectedly high at 87%.i put as much info in the attached file as i could.

View 1 Replies View RelatedI have recently switched to fibre optics and I have decided to reuse my Linksys E4200 that was previously used with a cable network. However, After installing the router using the disk provided I was unable to connect to the internet even though my computer was able to connect with the router. What can I do to solve this prob. I have tried restarting the modem to the factory settings and the same problem recurs.P.S. The modem was installed to another router provided by my service provider.

View 9 Replies View RelatedI have a lab setup and I want to test a point-to-point connection between two 2921 routers in a lab environment, without going through an ISP. I have a HWIC-1DSU-T1= in each of the routers. I have already configured ip addresses to the router interfaces, eDo I need to set any CLOCK RATE or BANDWIDTH commands or anything like that, since my traffic will not actually be going through an ISP during this lab test?
View 5 Replies View RelatedI am deploying PBR at the moment in a simple configuration. The 'ip policy' is applied to a sub-interface on a 2811 and all ACLs and route-maps look good. I am using NAT also in this configuration. It is a very simple build, basically stating that all traffic inbound on this sub-interface is to use a next hop of x.x.x.x
My testing is not working, but i need clarity on this. For different reasons, i am not able to tests with hosts on the relevant VLAN yet, as there is not. So i am testing on the local router using the sub-interface as the source IP. i.e. 'ping 8.8.8.8 souce int fa0/0.99' or telnet www.cisco.com 80 source fa0.0.99
Nat appears to be working, but my debug on ip policy is not showing any hits. Will my tests work when i am sourcing packets from the locally connected interface?
I have done a bunch of research in trying to re-use an old card/router for testing our new MPLS link. I have a 45m DS3 and was wondering if the PA-MC-T3= card will work UN-channelized. I have tried the "no channelized" command under the controller to no avail. I believe that the card only works for channelized T1's.
View 1 Replies View RelatedMy company is moving the datacenter to our new building on Saturday, however the users will remain at the old building until late next month so they bought a 100M Metro E VPLS circuit through their ISP. I went to test it today but could not ping the workstation from my laptop. I wanted to do some bandwidth testing with iperf but could never get to that point because ICMP connectivity wasn't even there. From what I understand, VPLS is just a layer 2 extension so they way I'm testing the circuit below SHOULD work, but it isn't. Spoke with the ISP and they tested the circuit end-to-end on their equipment which was fine so am I missing something?

View 1 Replies View RelatedI am working at a client site today. The client has a large Frame Relay Hub Spoke network. The Hub is at the HQ location, and then there are about 15 spoke sites in remote offices.
We are having an issue with the frame between the HQ and one of the spokes. We are currently working with our dear friends at AT&T to troubleshoot the issue. AT&T yesterday was trying to run a local loop test to the router at the remote (spoke) end. We were working iwth them in trying to put the remote router (which we manage) into a loopback mode. We were trying to use controller commands
COOP-Rappahanock#conf t
Enter configuration commands, one per line. End with CNTL/Z.
COOP-Rappahanock(config)#controller ?
% Unrecognized command
COOP-Rappahanock(config)#controller
That we seem to run out of options...
How can we put the subinterface that is the other end fo the frame into loopback mode so that a local loop test can be done between us and AT&T (provider)?
We are having issues transferring a 200GB VHD file across our point to point without being corrupted in the process. Any good application for testing the line quality across the point to point?Preferably we want something free, but if there is an in depth tool that costs money, we are open to that option as well.

It is full of great open source testing tools and has easy to use instructions for them all.However, to be more specific, I am looking for a packet generator that can simulate network packets over an extended amount of time. So the end result is I have this generator test my physical network for an hour but it simulates a week of real network traffic. Any tool, ideally it be open source?
View 5 Replies View RelatedHas anyone tested QoS on the new E3000? Whenever I add an application (e.g. Voice Device) and set priority to Medium or High, my upstream bandwidth for everything else is immediately cut significantly, even when I'm not using the priority application.
For example, with QoS disabled, I can consistently get 10Mb upstream (speedtest.comcast.net). As soon as I enable QoS, upstream is capped to exactly 2Mb! On my old router, there was an option to set the total upstream bandwidth -- but on the E3000 there is no such option that I can find.

View 2 Replies View RelatedI've got an SG300-10P switch and am trying to use it to create a testing environment for a Fiber Test set. What I would like to do is get two hosts, A & B, plugged into ports 1 and 3 on the switch, to talk to each other, but forcing the traffic to be routed through the two Combo ports 9 & 10. Please see the attached diagram.I've attempted to configure two VLAN's, 10 and 20. Vlan 10 is used for traffic between Ports 1 and 9, Vlan 20 is used for traffic between Ports 3 and 10.I don't really care whether the traffic is tagged or untagged as it passes between ports 9 and 10.
I've tried various combinations of tagged/untagged ports, PVID's, etc. As a first test I've bypassed the Fiber Test set and simply created a direct connection between ports 9 and 10. I am unable to get the traffic from Host A to Host B to get routed through ports 9 and 10 (I ping each host from the other and get no response).

View 3 Replies View RelatedWe have a 5 node VMWare cluster connected to an EMC NS20 using VMWare over NFS.Right now, our only bottleneck is network and even that is not limiting. We are considering updating our infrastructure and since networking seems to be the the only real issue, they want me to research that first.So I thought I would get a server, throw in a 10Gbe NIC, get a cheapo 10Gbe switch, get some cheapo NAS (or build one) that can do 10Gbe and start testing...Wrong. What a CF 10Gbe still is. At first I just assumed I'd go with 10Gbe over copper. How naive of me. So once I realized that the most "cheapo" 10GBase-T copper switch would run me about $9,000, I shrugged and starting looking at 10Gbe over optics...
IS there a cheapo (relatively) switch out there for someone wanting to test 10Gbe?? Like $5,000 or less?EDIT: BTW, before this goes off-topic into teaming 1Gbe connections being good enough and such, let me say that we are planning for the future here. As I said, we aren't currently limited in any area right now. However, we see that if there was an area we need to focus on, it would be network. So to that end, we'd like to start testing what the future has to offer. We've already tested and are using link aggregation and such at the 1Gbe level.
A Network Lab (governmental) did not let our cisco 2960s switches to be imported to the country and said "according to my lab tests, the maximum mac that your switch can learn is about 500 but as cisco says it should be about 8000"
they did not give me their software but i like to test it myself
Is there a software which generates thousands of MAC and inject them into switch to test the real amount shown in show mac count ?
