VPLS Testing Missing Something
Dec 13, 2011
My 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?

I could do configuration of a VPLS in 3750, I have doubt about whether the configuration is similar to that of 7600, but is so I could recommend some document to observe the configuration.

I can't find any configuration info for any MPLS layer 2 extension features for the Nexus 7k devices, is this a strategic decision by Cisco to promote OTV?

We have 7606 with WS-SUP-32GE-3B. is it possible to configure VPLS using this settings or we need additional cards. as far as i have found googling is that either ES or SIP cards are required facing the core. But all are mentioned for SUPs other than WS-SUP-32-GE-3B.

I have implement MPLS L3VPN on my network to provide service to customer and right now we plan to have service VPLS on our same router. What is needed to run the VPLS in our MPLS network ? I heard that we need addictional switching module and upgrade my IOS to support it but I am not sure.

One of our customer would like to connect 3 datacentres and decided to use VPLS to extend layer 2 VLANs . For this purpose they have bought six Cisco ASR1000 edge routers( two at each side).They also wanted to buy MPLS SP backbone but have decided to buy 2x10G dark fibre links instead.My question is,
1-Will it still possible to run VPLS over dark fibre? Because all the documents I read regarding VPLS are deployed over MPLS backbone.
2-Any sample configuration for implementation VPLS in ASR1000 ?

Does VPLS is supported on the Cisco ASR1001?With the feature navigator it looks like the ASR1001 is the only ASR1000 series router with VPLS support but I can't find any documentation confirming this.

I understood that service provider will use hardware Alcatel 6850 on the distribution/core and Zyxel 2108G on customer access level.query is that service provider says it's not VPLS which should work most probably through MPLS network of ISP.ISP noted that it would be direct 802.1q VLAN between two sites without any Layer3 on ISP side.
How to:
- understand what kind of connection this will be?
- is this connection is fine for customer?
- identify if this kind of connection will be fine for converge network (voice+data) ?
- what should I ask to ISP to clarify details?

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.

I always test ethernet family links(E, Fa, Gi) sending pings with MTU equal to 1500. Since most hosts uses MTU 1500 I think is not necessary to test using a high MTU size like 18024.

At 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?

I 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?

I 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.

I have been in this field for a few years and I found this book, Network Performance Toolkit: Using Open Source Testing Tools, to be very useful. 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?

I work for a company that buys used cisco equipment and we are trying to get a basic test center set up. What is the best way to perform basic router testing? We have been trying to come up with something for about 3 weeks and so far all we can do is get in the configuration and play around.

Has 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.

I am looking for the way how to disagle logging of one user. We are using one testing user for checking accesibility of ACS from large number of switches - this checking exhausting logs quite quickly. Is it possible to disable logging of such user?

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.

I 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 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.

I'm looking to test fram relay connections in a lab environment i'm building at home. I have a couple of 2610 routers that are barebones and am looking to get some serial modules. Are (2) WIC-2T's all I would need to create those test connections? Also on a side note are the any modules for the 2610 that have fast ethernet connections. I would like to have that so I can create a router on a stick model off of the 2600's.

ASA 5540 8.2 (5)I have tried many combinations of command line syntax suggested in this forum but none are providing success so far.
I want to ping from the Inside Interface across to the Outside Interface and visa versa.I have tried various ACLs as well as "inspect icmp" in the config, etc still no go.
I can ping each interface from the console command line but cannot ping across each interface. [code]

From ASA 5520 we tested the interface failover it not working even the interface are getting monitor .
primary is active.
Manually we shut the outside interface of the primary device configuration is getting reflecting in secondary as outside interface shut. Interface failover not happen.
ii All the interface are getting monitor when we gave command sh failover. even though when we shut outside interface failove not happening.
how to do the interface failover in ASA 8.4 version.

I have developing a utility which lets a user do the following :-
1)Identify the internet gateway device / router using uPnP
2)Check for the portmappings present in the gateway
3)Add / remove a port mapping from the gateway device
4)some other functions like loopback interface testing etc
Now , I need a router simulator (or any other way )which supports the following to test my work uPnP+ NAT +can be configured using SOAP XML messages although this is not a requisite as I am using Microsoft's SDK for uPnP ?Host 3 (or may be 4 is the RAM allows) virtual machines , connect them into a subnetwork using this software and then testing for the above requirements .

I'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).
