What is l3 interface in Juniper?
Understanding Layer 3 Logical Interfaces You can use Layer 3 logical interfaces to route traffic among multiple VLANs along a single trunk line that connects a Juniper Networks switch to a Layer 2 switch. Only one physical connection is required between the switches. .
What are CLI modes?
The CLI has two modes: Operational mode—Use this mode to display the current status of the device. In operational mode, you enter commands to monitor and to troubleshoot the network operating system, devices, and network connectivity. Configuration mode—Use this mode to configure the device.

RE: Shell Mode in junos CLI Although if they have sufficient permissions then those users can switch to the shell via the “start shell”, “start shell sh” or “start shell csh” commands etc., although “sh” is really “bash”.
Do Layer 3 switches have IP addresses?
Layer 3 switches have separate IP addresses on individual interfaces. Some devices have a factory default, such as 10.157. 22.154, used for troubleshooting during installation.
Can we configure NAT on L3 switch?
2) L3 Switch doesnt have an option of NAT (Private to public and vice versa ) but a router has 3) Router supports encapsulation techniques like GRE,IPSEC even MPLS if appropirate licenses are put …
What is a Layer 3 interface?
Layer 3 interfaces forward packets to another device using static or dynamic routing protocols. You can use Layer 3 interfaces for IP routing and inter-VLAN routing of Layer 2 traffic. Routed Interfaces. You can configure a port as a Layer 2 interface or a Layer 3 interface.
What is the command to know the switch port is layer 3 or layer 2?
Table 17-4 Chapter 17 Configuration Command Reference
| Command | Description |
|---|---|
| [no] switchport | Layer 3 switch subcommand that makes the port act as a Layer 2 port (switchport) or Layer 3 routed port (no switchport) |
What is l3 VLAN?
The Layer 3 switching function needs a virtual interface connected to each VLAN internal to the switch. These VLAN interfaces act like router interfaces, with an IP address and mask. The Layer 3 switch has an IP routing table, with connected routes off each of these VLAN interfaces.
What are the three 3 CLI modes?
Cisco has at least 3 main command line modes: user EXEC mode, privileged EXEC mode, and global configuration mode.
What is the difference between the active configuration and the candidate configuration?

What is the difference between l2 VLAN and L3 VLAN?
I answered them, Layer 2 VLAN is a single broadcast domain. It works on layer 2 (Datalink Layer). They can communicate only within it. And L3 VLAN is an Interface, that works on Network Layer.
How do you configure inter VLAN routing using layer 3 switching?
How to Configure Inter VLAN Routing on Layer 3 Switches?
- Assign port Fe0/1 in VLAN 10 and port Fe0/2 in VLAN 20.
- Create trunk port Fe0/24.
- Enable layer 3 routing and create VLANs 10 and 20 in the switch database.
- Configure Switch VLAN Interfaces (SVI) to acts as a virtual layer 3 interface on the layer 3 switch.
- Conclusion.
Can a Layer 3 switch be used as a router?
A layer 3 switch is both a switch and a router: it can be regarded as a router with multiple Ethernet ports and with switching function. layer 3 switch enable packets switching by inspecting both their IP addresses and their MAC addresses.
How does a Layer 3 switch route?
Simply put, a layer 3 switch combines the functionality of a switch and a router. It acts as a switch to connect devices that are on the same subnet or virtual LAN at lightning speeds and has IP routing intelligence built into it to double up as a router.
