How to connect two untagged VLANs from two different switches?
One cable goes from each of the different VLANs on the L2 switches into different VLANs on the L3 switch. As long as STP is disabled this seems to work fine. However, we tried this same scenario on this Cisco Small Business switch and only one of the two untagged VLANs on the Cisco will pass traffic at a time.
What happens when I unplug a juniper VLAN?
I believe that whenever the VLAN that is on the default (VLAN 1) is plugged in, the other (the one we created) shuts down but when VLAN 1 is unplugged, the other VLAN immediately starts to work. What seems weird is that the Cisco seems to learn the Juniper’s MAC on the VLAN that doesn’t work and the Juniper learns the MAC on the one that does work.
How does inter-VLAN communication work on EX-series switches?
For traffic passing between two VLANs, the switch routes the traffic by using a Layer 3 routed virtual interface (RVI) on which you have configured the IP address of the subnet. Now inter-VLAN communication does not work on EX-series switches. How does one troubleshoot the problem?
How are switch ports assigned to a VLAN?
Assign at least one switch port interface to the VLAN for communication. After assigning one or more interfaces to the VLAN, the interfaces function in access mode. All interfaces in a single VLAN are in a single broadcast domain, even if the interfaces are on different switches.
Is it possible to route VLANs to different subnets?
VLANs, in their simplest form, are simple to configure and associate with their respective ports. You mentioned that this is a L3 switch, configure some switched virtual interfaces (SVI), put the VLANs on different subnets, and route between the VLANs. Sure you can do this!
What’s the best way to connect two switches?
Switch A we assign an IP address to VLAN 3 and enabling routing on the VLAN. On both switch A and switch B we will keep things simple and use interface 1/e1 for the connection between each switch. Setting both switches 1/e1 to general mode, allowing the additional VLAN 2,3, and keeping the PVID of 1.
Can a server connect to a VLAN 3 switch?
A server connected to switch A on VLAN 3 should be able to communicate with another Server connected to switch B that is also in VLAN 3. Without the use of a router the devices in VLAN 3 will not be able to communicate with devices that are outside of their broadcast domain (i.e. VLAN 2 devices could not reach VLAN 3 devices)
