Thanks for Vid. How do computers on each VLAN get their IP addresses? Is each switch doing DHCP? Are they setup to get IPs from the router... and then the router is able to tell that the computer is on a separate switch VLAN?

@Pancajayna Жыл бұрын

In this scenario, they were static ip addresses. In the case of a router doing DHCP, whatever access port the router is connected to, the VLAN configured to that port will come into play. The router will give out ip addresses to the machines connected to the other ports that are also configured to the same VLAN as the Router's port.

If we only have 1 vlan's traffic going across a connection between 2 switches, and it's not the native vlan we need to create an access port (or trunk if desired) but if it is 1 vlan, and that is the native vlan on both devices, we can just not do anything and traffic will successful traverse the connection yes?

U dindnt show ping from vlan 10 pcs to vlan 20 pcs, doest it work ? Its different subnet!!! u show ping from pcs that are connected in vlan 10 correct

As long as you turn on "ip routing", given the switch is layer 3 capable, and SVI or interface VLANs are on the same switch you will be able to ping between VLANs (if from PC it must have correct default gateway set). If the SVIs were on different switches you would need to set up static or dynamic routing to ping between the VLANs.

Great video, I am trying to configure an EX4400. I am able to set an interface to a particular vlan, but when I try to commit, I get the following response " Access interface can be part of only one vlan, error: configuration check-out failed". Can you please advise on what I may be doing wrong? This is a new switch, I upgraded the firmware to Junos version 23.2A1. The unit appears to be in proper working order, but I can't get passed this vlan configuration issue.

@lezunetworking Жыл бұрын

Could be a few different things, first check would be to verify there are no other vlans configured directly on the interface. If that checks out, check for any interface-range commands that could possibly include that interface. I would need to see the configuration of the interface itself to help further.

can the computer from vlan 10 ping the computer from vlan 20?

Why there is ge-0/0/1? Couldn't be ge-1 ?

@lezunetworking Жыл бұрын

Hi, sorry for the late reply. If you have multiple switches that are stacked together, the other ones number will be the first number, so like switch 2 port 0 would be ge-1/0/1. The middle number is if you have expansion module ports.

@1999Zahra Жыл бұрын

Something very confusing for me: the use of interface-mode vs port-mode. For example. I've seen "set interfaces ge-0/0/0 unit 0 family ethernet-switching interface-mode access", but could one also do "set interfaces ge-0/0/0 unit 0 family ethernet-switching port-mode access"? What would be the difference? If I ask ChatGPT, it says that setting port-mode to access implies interface-mode to access as well but not the other way around. First of all, I do not understand the difference and secondly, I do not trust the unequivocal nature of ChatGPT's answers.. I do not trust the trustworthiness of ChatGPT (but that's another discussion) Same quesion goes for "trunk" mode...

@lezunetworking Жыл бұрын

Hi, those two are the same command, with the "port-mode" being the newer one. Basically Juniper changed a bunch of command syntax at once and some commands are now different than they were before. You can look up Juniper ELS to see about that.

i think port mode is for all interface inside phyiscal port but one port can have many interface

Excellent demo, question though, what if I make R2 and R5 as OSPF area 1 and their associated loopback 0s also area 1, would it be possible to establish the MP-BGP between R2 and R5?

Do you need to add switchport trunk allowed vlan 10, 20? If you dont add it, shouldnt it just allow all vlans between the 2 switches?

Nicely explained, now if our primary route is up then, is their a way to switch back to it automatically.? Or we need to use it with HSRP?

I think when the link comes up again it will automatically start going over the primary connection again. I will be testing this tomorrow.

Sir can i ask? What is the purpose of encapsolation that you put on configuration after switchport mode trunk

@lezunetworking 2 жыл бұрын

Previously, Cisco utilized both ISL and dot1q as means to tag frames across a trunk. ISL (Inter-Switch Link) is a Cisco proprietary protocol that is no longer used but was the default on older switches. Dot1q is what other vendors use and is a preferred method to encapsulate a trunk, we just need to specify it on some older models of Cisco switches.
