How does a device attached to a Cisco IP Phone send data to the switch?a. As tagged (using the voice VLAN)b. As untaggedc. As tagged (using the data VLAN)d. As tagged (using the CoS value)The correct question is A in the book though it said that tagging is switch process PC's doesn't tag frames.
View 4 RepliesPacket Sniffing is mainly used on non-switched networks to display data that was supposed to be sent to nodes other than yourself, allowing you to see information such as usernames and passwords etc.My question is, why can this technology not be used as easily on a switched network? When nodes send data through a switch does it become encrypted?
View 6 Replies View RelatedA few weeks ago, I bought a Linksys AE2500 wireless adapter, and it's worked fine up until a few days ago. A few days ago, when I turned on my computer, I could not connect to the internet. I've tried uninstalling and reinstalling the drivers, but I am denied every time; the message I get is "A device attached to the system is not functioning".I've tried connecting to the internet with my other wireless box I used prior to getting the AE2500 and I cannot connect with that, either. The only way I can connect on this computer is with an ethernet cable.

The SVI sends the flow data just fine, however I also continue to receive flow data from most other interfaces.
I have attached a screenshot of one of our netflow collectors indicating that many of the interfaces are sending flow data even though not configured to do so. We have two different netflow collectors, from different vendors and both confirm the same interfaces sending flow data.
Normally I wouldn't care and ignore it, however one of them uses a license limit by interface and is a bit problematic.
So i have a dell latitude e6400 laptop running windows XP. Now whenever I connect to my home wireless network, it will connect fine but randomly it will stop sending or receiving data. Therefore i cannot connect to any websites and i get a connection error. I check my connection though and it is running through an excellent connection.

If so, do you recommend any other firmware that can do the task, and is compatible with my router?

View 0 Replies View RelatedI have some specific traffic that I am attempting to pull off of VLAN 310 at the router, apply a route-map that sends this specific traffic back down to the switch on VLAN 55 (and the private address) and once it hits the switch apply a route-map on that VLAN 55 interface directing the same traffic over to the 72.x.x.9 address which goes through a FAP box back up to the router on another interface.
I have attached the config information, I know this isnt the best practice way to do this however right now this is how I have to do this.When runing a trace from the net traffic stops at .2 and when running a trace from my test /30 it stops at .2 as well. I am not sure what to do at this point

Mgmt Vlan 1 (default) Data VLan 10 (with access to internet) Is there a way to have a PC attached to a SG300 switch such that it can both access Vlan 10 for data and Vlan 1 for managment ? The PC's port clearly needs to be untagged PVID on vlan 10. I have tried adding vlan 1T and setting the port as a trunk port but to no avail, The switch is currently level 2. I am guessing this might not be possible in level 2 without setting the mgmt vlan to 10 ?.

View 3 Replies View RelatedI'm in need of a device which can switch to several items which has the same mac address. I heard that there may be devices that can handle this, by for example mapping fake unique mac addresses in the switch to each on of the same mac addresses on the devices, so when you try to send something to a "device with the same mac address" you send it to the faked address in the switch and the switch just forwards it.
View 1 Replies View RelatedI have a recently purchased 28 port SG300 switch. Everything is working well. Unfortunately there is so much traffic flying around that a 10MB half duplex device is struggling to function as it is overloaded. Removing some of the sources of traffic fixes it.
Fortunately I only need to access that device from one PC on the network. That PC however needs to access everything else on the network.
Is there a simple way to shield the slow device from everything except traffic from the PC ?
The switch is in Level2 mode at the moment. Everything is on a single sub net.
