Viewing the IP Address Table6-2
The display panel of the IP Address Table window contains address information
for each entry in the table. If there are more entries in the IP Address Table than
can fit in the display panel, scroll bars displays so that you can view the
remaining entries in the table.
Interface Index
The number of each interface on which this system can send and receive IP
datagrams.
IP Address
The addressing information for one of this entity’s IP addresses, according to the
ipAddrEntry. A device with multiple interfaces, such as a bridge, can have
multiple IP addresses.
Subnet Mask
The subnet mask associated with the IP address of this entry, according to the
ipAdEntNetMask. The value of the mask is an IP address with all the network bits
set to 1 and all the hosts bits set to 0. A subnet mask identifies the network and
host portion of a device’s IP address. Octets in a dotted decimal notation subnet
mask set to 255 indicate a network identifier. You set a device’s subnet mask in the
IP Routing Table.
Broadcast Address
The value of the least-significant bit in the IP broadcast address used for sending
datagrams in the (logical) interface associated with the IP address of this entry,
according to the ipAdEntBcastAddr. For example, when the Internet standard
all-ones broadcast address is used, the value will be 1. This value applies to both
the subnet and network broadcast addresses used by the entity on this (logical)
interface.
A broadcast address has a hostid (the portion of the IP address that identifies the
host) with all bits set to 1 or 0. This field displays whether all 1s or 0s will be used
to address IP packets that are sent as network broadcasts. A broadcast reaches all
hosts on the network.
Reassemble Max Size
The size of the largest IP datagram which this entity can reassemble from
incoming IP fragmented datagrams received on this interface, according to the
ipAdEntReasmMaxSize. The maximum size of a complete IP datagram is 65,535
bits.
Fields in the lower left section display the following information:
Number of Table Items
The number of IP address entries in the IP Address Table.
Interface Description
The Interface Description (ifDescription) for the currently selected interface in the
IP address panel.
