The proper resolution to the problem is listed in the article quoted: To change this new default behavior, create the following registry entry: SUBKEY: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters Value Name: AllowNBToInternet Type: Dword Value: 1 Default value of the flag: 0

So it looks like this is working now, in the end the particular devices I was pinging didn't have the right default gateway and/or subnet mask setup by the equipment installers. I incorrectly assumed that if the switch could ping them then it was good enough and the device should be able to ping other subnets but it doesn't look like this is the case.

What is the default gateway and IP settings for the End Machine? This might indicate that the End Machine is not routing IP addresses outside its subnet to the correct gateway. "Running traceroute to a 192.168.5.x machine from the switch turns up 0.0.0.0 as the first hop. But pinging the same machine from the switch turns up successful."

You can't do VSS with the 3850's. You could stackwise through the stacking ports but that would require them to be somewhat near eachother. You can setup HSRP/VRRP/GLBP with a virtual IP to provide next hop redundancy. however, you would not be able to form a functional etherchannel from one device to both switches.

On Linux server you need to create the vlan interfaces and assign static IP addresses. Follow the official Ubuntu documentation for details 1. Configure DHCP to listen to all VLANs except the one facing the cable modem. You will need separate DHCP subnet for each VLAN. Make sure that you send via DHCP as default route the IP of the VLAN interface directly ...

I suppose it is a license issue with the product. As this article: Cisco IOS Software Licenses: What’s What for Layer 2 and Layer 3 Switching – Part 1 explains, you will need a LAN Base License to have Layer 3 switching capability for your switch. The four common Cisco IOS Software feature licenses for switching are: LAN Lite: ...

Is this question about the HyperV Host server or a Virtual Machine on the HyperV host Server? Are you running Server 2012 or 2012 R2? If for the HyperV Host Server - How many NICs do you have in you HyperV host server? you say that you have a DOT1Q connection from you CISCO Switch so you imply you want to create a trunk? If you have multiple NICS in your ...

If you just have one cable running to the Hyper-V host and you just have one virtual switch, you can just add the second IP in the advanced IPv4 settings of the network adapter in your VM. If you have multiple network adapters and connections on your host, it will require a little more.

Probably what's happening is that you're seeing IPv6 broadcast traffic on your subnet, as per what you posted from a tcpdump output here: 12:19:41.622297 IP6 (hlim 1, next-header UDP (17) payload length: 112) fe80::a4a0:460b:c99a:c992.dhcpv6-client > ff02::1:2.dhcpv6-server: [udp sum ok] dhcp6 solicit (xid=455863 (elapsed-time 700) (client-ID hwaddr/time ...

The 2960-S is a layer 2 switch. If you need routing between VLANs, you need a router.

I assume we are talking about 802.11q. To create a trunk port you need to set that port to tagged. All other port in that Vlan are untagged. The switch will add a tag to all. You can have tag ports. Tag port mean the packets have already a VLAN-tag, i.e. they are tagged by the network device connected to this port.Your switch will not add or remove the ...
