Hi, i wanted to know if there are any gpon module compatible with Huawei that has the ability to change the serial number. Thanks.

Seeking advice concerning which portion does cloud take part in networking

Hello guys!!! I’m currently working on to become a network engineer. I passed CCNA in last May and keeping up to CCNP. But lately, cloud is also trending in every aspects of fields , in which part cloud is useful for networking ? and as a network engineer what ability of cloud or certi should i have ?Any replies are much appreciated...best regards,

How would you interface between dense mode routers and sparse mode multicast routers?

This is an IPTV environment. There are two geographically separated environments managed by different teams. Normally when we need to push video back and forth we drop it onto a "video proxy", something like a Cisco DCM that won't allow reverse flow traffic; to protect the source network. Problem is this particular application needs to be able to speak unicast bidirectionally back to some middleware and a VOD server cluster.

Complicating matters is the source network is all dense mode, and it ain't changin'. The remote network gear is only capable of sparse mode (Arista). These two networks need to talk. We have the bandwidth to statically join all groups (around 500) if that would help the solution along -- this wouldn't be a bandwidth waste as we are normally joined to all groups anyways.

So, I turn to the brains of reddit. What would you do?

Connecting a switch

I work for a large business that has terrible wifi and few active network ports. Am I able to use a cable from a wall network port into a 8 port switch to extend port capacity? It is only temporary, as I need to hook 10 laptops to the network for setup. Or do switches need to be hooked up to the router? Thank you in advance!

Interaction between TCP Congestion Control and Flow Control

Hi all! I've read many articles about the difference between congestion control and flow control, and the answer is mainly in that congestion control avoids overloading the network whereas flow control avoids overloading the receiver.

However, I haven't been able to find a good explanation on how these two interact with each other. For a TCP connection, both mechanism is at work, right? On a high level, they both specify a window size which limits the amount of data sent by sender. And it looks like the unit of both windows could be bytes.

So, can I roughly understand it as the actual amount of data is the min(limit_by_congestion_control, limit_by_flow_control)?

Thanks for all help in advance!

What security features do I need in an AP?

I want to build a network where one of the requirements is to isolate guests from each other as well as from the private LAN.

I assume this is called "Layer 2 isolation" although I don't find much discussion on the topic when googling around. At the moment I'm looking at picking up a couple Unify AP Pros. Is this possible? Having each guest in their own Vlan or at a minimum some way to block communications between wireless guests?

Moronic Monday!

It's Monday, you've not yet had coffee and the week ahead is gonna suck. Lets open the floor for a weekly Stupid Questions Thread, so we can all ask those questions we're too embarrassed to ask!

Post your question - stupid or otherwise - here to get an answer. Anyone can post a question and the community as a whole is invited and encouraged to provide an answer. Serious answers are not expected.

Loopback testing on a gigabit ethernet carrier fiber interface.

Okay so back in the stone age days we use to loopback a oc3/ds3/t1 interface to itself and run ping tests to the ip address on the interface. We would keep moving the loop closer to us until the problem stopped(no more dropped packets). This would point us to where the problem is. So fast forward to now (the age of gigabit ethernet). How do i run this same test. it seems like it works when it's physical loopbacked (same light going in and out).

But when i have the carrier loopback the remote end i don't see the same packet input as the same packet output. i've been researching this all weekend, and it looks like ethernet oam/cfm is the way i should go about this. Thats fine if it's the only way but just trying to make sure i can't do a simple ping test with the equipment already in place.

TLDR: can i loop back a fiber gigabit ethernet circuit at ANY point along the path and test with consumer** equipment.

Is it still true that Viptela only allows one of each "color" to be present on a vEdge?

Cisco documentation suggests that is still the case, but I wasn't sure. It seems like such an arbitrary limitation. Can anyone tell me if this is indeed still a limitation, and whether or not they are any plans to remove it? Or is it just a strict requirement for OMP to operate?

Need help with my school lab. Are 2 management IPs required for intervlan routing? Should I put one IP on SVI and then trunk connection? Or 2 SVIs?

Sorry if my question is a little confusing, I am working on a lab for my school. I'll try my best to explain.

So I have VLAN56 on one switch with an IP address on the vlan interface (56) of 10.1.1.2 255.255.255.0. I am trying to add VLAN56 traffic to another switch so it can cross over into my other broadcast domain.

The catalyst has the option for IP routing. My question is can I simply add VLAN56 to the other switch, and trunk the connection between the switches?

Or would I have to create VLAN56 on the new switch, and also give it an SVI of 10.1.1.3 255.255.255.0?
