A switch virtual interfaces (SVI) or VLAN interface, is a virtual routed interface that connects a VLAN on the device to the Layer 3 router engine on the same device. When you enable VLAN interface creation, Cisco NX-OS creates a VLAN interface for the default VLAN (VLAN 1) to permit remote switch administration.

What is the purpose of the SVI on a Cisco switch?
The SVI provides a physical interface for remote access to the switch. The SVI provides a faster method for switching traffic between ports on the switch.
What is difference between VLAN and SVI?
A virtual LAN or VLAN is any broadcast domain that is segregated and isolated at the data link layer OSI layer 2. VLANs reduce the load on a network by keeping local traffic within a VLAN. An SVI is virtual and has no physical port defined and performs the same functions for the VLAN as a router interface.
What is a SVI used for?
A Switched Virtual Interface (SVI) is routed interface in IOS representing the IP addressing space for particular VLAN connected to this interface. There is no physical interface for the VLAN and the SVI provides the Layer 3 processing for packets from all switch ports associated with the VLAN.
Is SVI a VLAN 1?
By default, an SVI is created for the default VLAN (VLAN1) to permit remote switch administration. An Switch Virtual Interface cannot be activated unless associated with a physical port. SVIs are the most common method of configuring inter-VLAN routing.
What is the default SVI on a Cisco switch?
An SVI is a virtual interface and VLAN 1 is enabled by default on Cisco switches.
How do I find my SVI IP address?
After the enable command is issued, the show running-configuration command or the show ip interfaces brief command will display the IP address of the switch virtual interface (SVI).
What is the difference between SVI and routed port?
SVIs generally provide Layer 3 services for devices connected to the ports of the switch where the SVI is configured. Routed switch ports can provide a Layer 3 path into the switch for a number of devices on a specific subnet, all of which are accessible from a single physical switch port.
How do I check SVI?
Sludge volume index ( SVI ) is calculated by dividing the settleability by the MLSS concentration. The SVI is always expressed in mL/g.
What are characteristics of SVI?
What are three characteristics of an SVI? It is designed as a security protocol to protect switch ports. It is not associated with any physical interface on a switch. It is a special interface that allows connectivity by different types of media.
What is VSI in networking?
Virtual Switch Interface (VSI) is a common control interface for MSSBU switches such as the BPX 8650 and the MGX 8850. The Virtual Switch Interface provides a mechanism for networking applications to control the switch and use a partition of the switch resources.
What does Ctrl Z do in Cisco?
Ctrl-Z: When in a config mode, ends the config mode and returns you to privileged EXEC mode. When in user or privileged EXEC mode, logs you out of the router. Ctrl-Shift-6: All-purpose break sequence.
How does Inter-VLAN routing work?
Inter-VLAN routing refers to the movement of packets across the network between hosts in different network segments. VLANs act as separate subnet on the network. To move packets from one VLAN to another and enable communications among hosts, we have to configure the VLAN network.
How do I convert SVI to Layer 3 switch?
Layer 3 Switch Configuration (4.3. 3)
- Create the VLANs. First, create the two VLANs as shown in Example 4-13.
- Create the SVI VLAN interfaces. Configure the SVI for VLANs 10 and 20, as shown in Example 4-14.
- Configure access ports.
- Enable IP routing.
Can we create SVI on layer 2 switch?
1.10/24, PC2-192.168. 1.20/24, PC3 – 192.168. 2.10/24, PC4-192.168. 2.20/24.
What is a Layer 3 interface?
Layer 3 interfaces are used to forward IPv4 and IPv6 packets using static or dynamic routing protocols. You can use Layer 3 interfaces for IP routing and inter-VLAN routing. An interface of which the status is always up. Routed Port. A physical port configured as a Layer 3 port.
