4.5 Route
This command group offers L3 interface and route entry configuration
4.5.1 Interfaces
Generally, Layer 3/routed interfaces are used to route traffic between
the VLAN, this is so-called inter-VLAN routing. That is, different VLANs
exchange data with going through Layer 3 interfaces and need not an
external router.
This switch performs Layer 3 switching only for IP protocol. To enable
Layer 3 switching on a specific interface, the following information must
be configured:
Name: the UNIQUE name used for managing Layer 3 interfaces
under CLI console
Type: VLAN type interface is virtual interface, which is VLAN-bind;
where
Port type interface is routed port base. One of the interface
types must be specified
VLAN: the interface associated VLAN (range 1-4000), this VLAN
should have been created as well as assigned with port member in
Layer 2. One VLAN ID can only be assigned to one interface
Routed port: where the traffic should be destined to. Routed port
does not perform Layer 2 functions. Note that you cannot configure
a mirror-to port, trunk port, or 802.1x authentication unauthorized
(auto/force) port as a routed port simultaneously. Routed port will
automatically become non-STP port when STP/RSTP process has
been enabled
IP address: the interface IP address
Subnet mask: the interface subnet mask
Status: interface up/down (Layer 3 switching works only amongst
the running up interfaces)
