AppleTalk
Interfaces
On the Switch 4007, an AppleTalk interface defines the relationship
between a virtual LAN (VLAN) and an AppleTalk network. An AppleTalk
interface has these elements associated with it:
■
Seed Interface — You can configure the interface to be a seed or
nonseed interface:
■
A seed interface initializes (“seeds”) the network with your
configuration information. This information includes the network
range and zone name list.
■
A nonseed interface listens for a seed router and then takes the
zone and network range information from the first seed interface
that it detects. After a nonseed interface obtains this information,
it can participate in AppleTalk routing.
■
Network Range — The contiguous range of numbers assigned to
the interface (for example, 20301 through 20310). Each router
attached to the network selects a network number from within this
range.
■
Address — The AppleTalk interface address, which is based on the
network range and a unique network node number (
1
through
253
)
and expressed in the format
network.node
. The network number
identifies the network. The node number uniquely identifies the
AppleTalk node on the network. The router selects the network
number from the range of numbers assigned to the network. It then
selects an available node number. Sample interface address:
20301.7.
■
Zone List — The zone or zones to which the interface belongs. You
specify the default zone name and up to 15 additional zones, for a
maximum of 16 zones per interface.
■
State — The status of the AppleTalk interface, which indicates
whether the interface is available ( enabled ) or unavailable ( down ).
■
VLAN interface index (VLAN index) — The VLAN that is associated
with the AppleTalk interface. When the system prompts you for a
VLAN interface index, it indicates the available VLANs that you can
associate with a new AppleTalk interface. For information on creating
VLANs, see Chapter 14.
