Certified Traffic Model (OSI Layer 3 And 4 TCP / IP)
Jun 23, 2011
I am looking for a certified (e.g. by the ITU) traffic model for the OSI layer 3 & 4. (TCP/IP). If there are definitions for different kinds of traffic, like idle-traffic (protocol only), surfing, file-transfer and all these mixed up.The reason why i am looking for it is that i am actually working at my bachelor thesis and need to simulate network traffic and its behaviour in/at a router. In particular i want to simulate the RTO (retransmission timeout) of a router with "realistic" traffic.

I have two 1841's connect to the Internet via DSL;
fa0/0 --- 1841-R1 --- DSL1 ---------------------[INTERNET]--------------------- DSL1 --- 1841-R2 --- fa0/0
I am on the LAN attached to fa0/0 on R1 and I need layer 2 connectivity to a device on fa0/0 on R2. I'm not sure if this is possible with 1841's or not? I made a GRE tunnel between the two and was going to add a BVI and bridge the tunnel at each end with fa0/0 at eah end, but the 1841's don't support BVIs so I'm a bit stumped here! Would L2TP work here?
R2 is a remote router running C1841-SPSERVICESK9-M. R1 is local running C1841-ADVENTERPRISEK9-M. I can't change the remote router so if the answer is not support in C1841-SPSERVICESK9-M I won't be able to do this.

i have set up a layer 2 tunnel on my 887va router and the traffic transmits accross this to my second 887va. unfortunately, I do not seem able to get the layer 2 traffic from my host PC and down the tunnel.
I believe the problem to be the router settings for the fastethernet aqnd forwarding this data out of the dialer port.
Here is my config:
Building configuration...
Current configuration : 3973 bytes

! Last configuration change at 13:03:15 UTC Thu May 2 2013

I want to configure layer 2 switched netflow on my cat 6509 running vss,
I have configured the 2 commands below
ip flow ingress layer2-switched vlan 1,2,3
ip flow export layer2-switched vlan 1,2,3
However, if I look in the config the export bit isnt there after?
It is running a PFC
VS-F6K-PFC3C
Should layer 2 switched netflow work in this chassis ? it says on the Cisco site that it works on the below
"The command is supported on Supervisor Engine 720 in PFC3B and PFC3BXL mode only and on Supervisor Engine 2 with a PFC2"

What are the benefits of using a Layer 3 switch as opposed to a router for distributing traffic? Basically the building I work in has a fiber line coming in which then gets connected to a Level 3 switch (NetVanta 1534) which is then connected to all the ethernet ports and what not. Why would they choose to use this device as opposed to a router? Or just a regular Layer 2 switch?

Is the E4200 DLNA certified? The spec indicates a "UPnP AV media server" but mentions nothing about DLNA. Cisco is a member of DLNA, so what gives? Will DLNA devices like blu-ray players work with the E4200 and be able to stream media from a USB drive attached to the router?

I'm very disappointed with this EA4500 DLNA feature this is one of the main reasons why i got this router.My Sammy TV can detect the USB that is attached and is able to view the files in the drive but when you play any video file larger than 1gb it does not work even shuts down my TV.Only on smaller files does it work flawlessly I know its not the TV because I have played those files on my previous Router (Netgear WNDR3800) and they even work when i connect the hard drive directly to the TV has any one else had this issue happen to them?

Point me in the right direction to determining what Cisco router model will fit in certain situations. I don't want someone to just tell me what I need, I want to be able to determine it for myself.I figure that some of the things that need to to be taken into account are processing power, memory, physical port needs, features available and services going through the router.

I can't find a way to enable UPnP or anything like it on my Motorola model 3360. I play online with my new xbox 360 and I have constant connection issues because it tells me my UPnP isn't enabled. I know my router isn't the problem because the problem continues even when my xbox is directly connected to the modem.

We have a Belkin Play N600 model F7D8302 v1 duel band router. It connects to the Blue Ray player about 40' away in living room and to ipad mini used about 15' in adjacent bedroom.I will not connect to the ipad when farther than 20' away anywhere in the house. I moved the router away from the computer as suggested in the manuel, still same problem. I tried to get support from Belkin and they said this is not listed as a supported product without buying something on their website. If I spend any more money, it won't be to Belkin as I have only owned this router 2 months now.

Our company is in the process of replacing our old firewall with a Cisco ASA since our old firewall can handle only 170 concurrent users and we are expanding fast. Can I know what are the considerations when selecting from the different models of ASA currently we are debating if we should buy a 5510 or a 5520 also can I know if cisco ASA also have a limitations on concurrent users online in a lan like our old firewall. By the way we are a Call Center company(going 500 seats) so we are using VOIP(Asterisk using SIP and IAX).
