VLANs are often associated with IP subnetworks. For example, all of the end stations in a particular IP
subnet belong to the same VLAN. Traffic between VLANs must be routed. You must assign LAN
interface VLAN membership on an interface-by-interface basis (this is known as interface-based or
static VLAN membership).
You can set the following parameters when you create a VLAN in the management domain:
VLAN number
•
VLAN name
•
VLAN type
•
VLAN state (active or suspended)
•
•
Maximum transmission unit (MTU) for the VLAN
Security Association Identifier (SAID)
•
VLAN number to use when translating from one VLAN type to another
•
When the software translates from one VLAN type to another, it requires a different VLAN number for
Note
each media type.
