Ip Interface Configuration - 3Com CoreBuilder 2500 Getting Started Manual

IP Interface Configuration
These instructions include information on defining
an IP interface through which you can manage
your CoreBuilder system. An IP interface contains
the following parameters:
IP address
This address, which is specific to your network,
is used for managing the system. The IP address
defines both the number of the network to
which the interface is attached and its host
number on that network.
Subnet mask
A subnet mask, a 32-bit number, uses the same
format and representation as IP addresses. The
subnet mask determines which bits in the IP
address are interpreted as the network number,
the subnet number, and the host number. Each IP
address corresponding to a 1 in the subnet mask
is in the network and subnet part of the
address. Each IP address bit corresponding to a 0
is in the host part of the IP address.
Advertisement address
The CoreBuilder 2500 system uses this IP address
to advertise packets to other stations on the
same subnet. In particular, this address is used for
sending RIP updates. By default, the CoreBuilder
system uses a directed broadcast (all 1s in the
host field).
IP Interface Configuration
Cost
Each interface has an associated cost. This value,
between 1 and 15, is used when calculating
route metrics.
The next three parameters apply only to
CoreBuilder 2500 systems running Extended
Switching software.
Type
The type of IP interface is one of the following:
VLAN supports routing between two VLANs.
System supports out-of-band management.
LIS supports ATM CLIP.
State
This parameter is the status of the IP interface,
which indicates whether the interface is available
for communications.
VLAN Index
This parameter is the number of the IP VLAN
associated with the IP interface. The VLAN index
indicates which bridge ports are associated with
the IP interface. When the menu prompts you for
this option, it displays a list of available VLAN
indexes and the ports associated with them.
