An SVI interface is a virtual L3-interface used to terminate or generate traffic in the switch group it is assigned to.

Each unit supports 4095 virtual switch interfaces sviX (svi0 ... svi4095).

Each SVI interface can be assigned to a switch group. Once assigned the interface becomes an active member of that switch group and can exchange traffic with other group members. All traffic ingressed by this switch group (depending on the rules set) that is addressed to this SVI interface as well as all broadcast and multicast packets will be processed by the unit.

Each SVI interface can have one or several IP addresses configured.

An SVI interface can act as a parent interface for VLAN virtual interfaces. In this case the VLAN interface also becomes a member of the switch group assigned to the parent SVI interface.

An SVI interface (or any other interface that uses it as a parent interface) can not be included into a switch group directly.

An SVI interface can be used for channel aggregation using lag interfaces.

The SVI interface is considered active once it is up and assigned to a switch group.

Command syntax:

  • "ifc sviN [IP address] up" - create the SVI interface and assign the IP address to it (optional)
  • "svi N group G" - assign the SVI interface "N" to the group "G"
  • "ifconfig vlanX vlan V vlandev sviN" - assign the SVI interface "N" as a parent interface to VLAN interface "X" processing traffic tagged with "vlan V".

NOTE

In order to exchange broadcast/multicast traffic via protocols that utilize broadcast/multicast packets (such as OSPF, RIP, DHCP) it is necessary to establish the communication with other devices, for this the following should be noticed:

  1. In case the broadcast/multicast traffic are in the switch group with SVI interface, the IP-address assigned to SVI interface should be used.
  2. In case the broadcast/multicast traffic are in the switch group without SVI interface, the IP-address assigned to the physical interface (Ethernet or radio) could be used.
  3. In case the broadcast/multicast traffic are not a part of any switch group, the IP-address assigned to the physical interface (Ethernet or radio) could be used.

Otherwise, the communication between devices would not be established and traffic exchange would not be processed.
