mediate routers or gateways, as well as the destination host. If the
Maximum Trans-
mission Unit
value is less than the size of a minimal IP datagram, the value will
automatically change to the minimal datagram size.
Network Mask
is used during routing to determine the portion of the address associated with the
network. All network bits are set to
1
and must be contiguous.
Routing Metric Count
is the number of network "hops" (network gateways in the overall path over the
internet) associated with this interface (usually zero). During routing, the interface
with the lowest count will be selected.
ICMP Redirects
specifies whether IP may add routes obtained by ICMP (Internet Control Message
Protocol), whose error and control function is used to send re-direction options back
to the source if problems are discovered.
RIP Flash Updates
is the frequency with which RIP messages will be sent to every neighbor node, con-
taining any changes to the routing table that occurred since the last full update (see
next entry).
RIP Full Updates
is the frequency with which updates of the entire routing table will be sent to every
neighbor node, via one or more RIP messages.
Connection Priority
prioritizes this interface for intra-nodal traffic; the higher the number, the higher the
priority. (This priority has no effect on traffic exiting a node.)
A priority is also configured in Node Defaults, as well as for each logical port, SNA
PU, LLC2 host, Bridge Port/LLC2 Interface, IPX interface, SVC Subscriber, and PVC
connection. The device processor in the node uses these priorities to help determine
the order in which it will process protocols.
When configuring priorities, be careful to consider the types of
traffic being routed on other connections in the node.
Bandwidth Allocation Group
assigns the IP interface to one of sixteen groups whose parameters regulate bandwidth
usage. See "Configuring Bandwidth Allocation Groups" on page 6-6.
Source IP Address
is the IP address of the end-to-end sender.
Destination IP Address
is the IP address of the end-to-end receiver.
Broadcast Address
is used to send to all LAN hosts on the network.
