Is a VLAN A 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.
Can we create SVI on layer 2 switch?
On a layer 2 switch like the Cisco Catalyst 2950/2960 we also have a SVI but you can only use it for remote management.
Does a VLAN need an interface?
Ports can be assigned to the VLAN, and all frames tagged with a VLAN ID of 10 will be forwarded across trunk ports and VLAN 10 access ports. This VLAN does not require an interface configuration to function properly.
What are two characteristics of SVI?
What are three characteristics of 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.
- It is required to allow connectivity by any device at any location.
Which is SVI for Layer 2 VLAN 10?
The first line in the example above creates the layer 2 VLAN 10. The following line creates an SVI for VLAN 10 (i.e the Layer3 interface). Although the third line is OPTIONAL, it is recommended that you add an interface description, which will assist in understanding the purpose of the SVI.
How does SVI interface config ( Cisco ) reduce network load?
SVI interface config (Cisco) VLANs reduce the load on a network by dividing a LAN into smaller segments and keeping local traffic within a VLAN. However, because each VLAN has its own domain, a mechanism is needed for VLANs to pass data to other VLANs without passing the data through a router.
What does SVI mean on a catalyst switch?
Platform: Catalyst switches, Nexus Switches 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.
Where can I find SVI on my router?
An SVI is a switched virtual interface and is normally found on switches (Layer 3 and Layer 2). It is also found on some newer ISRs (routers) such as the 1800/2800 series. There is no physical interface for VLANs, but rather a “virtual” interface.
