Wake On Lan TP-Link WR740N.

Im trying to setup Wake On Lan for a remote PC in another location using the following
instructions: https://www.howtogeek.com/192642/how-to-remotely-turn-on-your-pc-over-the-internet/
Unfortunately, I am not able to forward the port on the modem to the "broadcast address"
192.168.0.255 and am getting the following error: Error code: 26106 The IP
address is not in the same subnet with LAN IP address. My router is TP-Link
WR740N. Is there anything i can do to resolve this?

Looking for best method and device to simulate a Taclane in gns3 or eve?

Hi I work in a secure environment that uses taclane to encrypt data from the CE side through the WAN and back to the CE side on the other side. I always struggle with understanding and implementing the best device and ultimately configuration to simulate the networks I work on the correct way. What is the best way? Some examples would be appreciated. Thanks for your help. For example you have site A that uses OSPF to connect to all other sites, then that site egresses to a taclane that connects to a PE router that maybe uses bgp or isis for WAN neighborship the hits the taclane on the other side. Hopefully this makes sense, sorry typing on mobile.

How to measure wireless signal strength without access to RSSI?

I am developing an app for iOS and wish to include a wireless strength signal indicator to show the user how good their wireless connection is however Apple has locked this down and does not allow access to wireless signal monitoring. I have come here to ask if there would be any other way I can show WiFi signal bars in my app by measuring the network in some other way? Would dropped packets from a ping be a good indication? The app I'm developing streams RTSP video - could the connection quality also be measured from the number of dropped frames from the video stream?

can anyone help setup this type of QOS ??

MTU on a virtual interface

Hi guys!

Can a MTU be set on a virtual interface or is it strictly a physical interface concept?

A bit of background info: I am troubleshooting packet loss over a VPN connection. I've determined that anything above 1250 doesn't go through. So I'm wondering if I can set a MTU exclusively for the ppp0 virtual interface.

Many thanks!

Cisco 9300-24UX-E as layer 3 distribution

I have a hospital with a campus style network and a horrible design, they have 3 large buildings all sitting off the back of a stacked 4500-X core and P2P circuits stretching layer 2 to access switches in each of the buildings.

My proposal is to create a resilient OSPF network between the buildings to create a full mesh "triangle" which requires an additional circuit from building 2 to 3. I am planning to use cisco 9300-24UX-E's as the new collapsed cores in each building and run OSPF over it for the resiliency.

Efforts have already been completed to give each building their own VLANs, but they currently all terminate on the core in building 1.

Having never worked with the new Catalyst 9XXX series, I have some questions:

1. Do you agree that this switch I have chosen is suitable? It needs to be mGig copper as they want to save money and also treat it as a server access stack
2. I know these switches stack, but am unsure if I need to buy a stack-kit/stackwise cables (i.e. do they come in the box?? no amount of googling can answer this for me).

The kit needs to be Cisco, as they are a Cisco-only shop and we'd rather keep it that way. But I am open to other suggestions on hardware models, and even constructive feedback on my design. They are very adamant that resilience is key here, hence the full-mesh approach with OSPF to failover the circuits, and the stacked collapsed-core at each building.

The end goal will also to have the most important of the 2 buildings connected via an etherchannelled P2P circuit, but that comes later...

Aruba logic vs Cisco logic for VLANs

Hi!

Sorry for the noob question...

I am using different switch vendors, that are using the cisco style for checking vlans on ports

• config
• Interface xyz
• assign vlans 2,3,4

Aruba switches are looking promising, but every example I found is showing, that I need to change the whole way to configure to:

• Config
• vlan 2
• add interface xyz
• vlan 3
• add interface xyz
• vlan 4
• add interface xyz

Is there any alternative to that method? For me, it's much more "straight forward" to configure one port and its vlans instead of vice versa.

Am I just to inflexible, or is there any other option?

Thank you for your thoughts

LAN client with non existant VLAN ID

I have a client on my LAN with the ip 192.168.11.77. However, I currently do not have a VLAN with the ID of 11. I also can‘t ping the client and connect to it with my mac over the ip address in the browser. My mac is on the 192.168.1.xx network.

I am not an expert with VLANs and Subnetting. How is it possible to connect to the client?

Thanks!

Promiscuous mode - am I understanding this right?

My understanding so far of promiscuous mode is as follows:

• I set my wireless interface on computer A to promiscuous mode
• I run wireshark capturing on that interface
• I connect computer B to the same wifi network

Given the above, computer A should now be capturing traffic addressed from/to computer B's ip

But this does not happen

Is there something wrong with my understanding?

I have reversed the roles of computer A and B to decrease the likelihood of hardware being at fault.

Eliminating the ISP factor in our business need advice

We want to setup WAN connection between our sites, currently we are using mostly cisco devices switches for LAN sites and 2 routers with hsrp config to ISP using bgp protocol, i was wondering if we can use WAN switches and connect all sites together without isp, we might lease some dark fiber
