  • "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".

In order to exchange broadcast/multicast traffic via protocols that utilize When the switch group has SVI interface attached it can pass the broadcast/multicast traffic transparently, however the device itself can use only SVI interface to receive the broadcast/multicast packets within this switch group. Therefore, in order to communicate with other devices via protocols, that utilize the 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:

In case the broadcast/multicast traffic are in the switch group with

SVI interface

, the IP-address assigned to SVI interface

should be used.

In case the broadcast/multicast traffic are in the switch group without SVI interface, the

 
If you have to use the physical interface for such purpose (e.g. to establish OSPF neighbor relationships using IP-address assigned to

the physical

Ethernet interface

(Ethernet

or to the radio

) could be used.
  • 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 processedinterface in case of DHCP) there are two options:

    1. Interface must be added to a switch group with no SVI attached (make sure traffic is not processed by another switch group).
    2. Interface must not be included into any switch group.
