I have a 3650 where remote access to the management interface is working and I can't figure out why. I configured an IP address on the management interface, but with no default route or default gateway configured, I'm able to access the switch from a remote subnet. I don't see why this is working. Can anyone educate me?   Running Config Current configuration : 8830 bytes ! !

I have a 3850 that has a multicast video encoder connected to it. I've tested playback with variety of decoders (primarily VLC player) that are connected to the same switch and the video is terrible. Multicast has been configured properly on the network. If I move the encoder to a different switch on the network, playback is fine. So at this point I'm thinking there is something going on on the 3850 that is causing packets to dropped somewhere, but "show int summary" shows no dropped packets on the encoder interface or the port I've been using to test playback. There is QoS configured on the switch, but it has been removed from the encoder and test interfaces.    I don't know what else to check or what might be causing this issue.  Thanks, Mike ...

I'm a bit confused on EtherChannel load balancing and I was hoping someone could clear things up for me.  I have a video application that uses a very high bit rate for each video stream.  For the sake of discussion, I have two switches connected via an etherchannel that consists of two 1Gbps links.  Switch 1 has two video sources and switch 2 has two video receivers. In order for each link in the port channel to not become congested, the two video streams must be balanced across the two links.  From what I've read on etherchannel it seems like it's possible that the switch may try to send both video streams across a single link.  Can anyone confirm if this is the case?  I'm mostly referring to this document https://www.cisco.com/c/en/us/support/docs/lan-switching/etherchannel/12023-4.html which says " You cannot control the port that a particular flow uses. You can only influence the load balance with a frame distribution method that results in the greatest variety."  Thanks, Mike ... View more

I have two SG300 switches connected via a port channel that contains two 1Gig links.  I have two video streams that I need to send across the link that are each just under 1Gbps, hence I need to ensure that the port channel is load balanced properly.  Is there a way I can test which link the stream will go down so I don't have to use trial and error by changing the IP addresses?  Catalyst switches have " test  etherchannel load - balance",  does the SG series have anything like that? Thanks, Mike ... View more

Can someone explain to me the purpose of MVR?  I ran across this article https://www.cisco.com/c/en/us/support/docs/switches/catalyst-3750-series-switches/71273-mvr-3750-config.html, but in the case of a 3750 I don't understand why you wouldn't just enable multicast routing rather than use MVR.  Am I missing something?   Thanks, Mike ...
