network mask for a non-subnetted network. For GetRequests, the FN100 will
always convert a value of zero into the correct network mask.
ipAdEntBcastAddr {ipAddrEntry 4}
Integer Read-Only
The value for the least significant bit for broadcasts, i.e., the constant 1.
ipAdEntReasmMaxSize {ipAddrEntry 5}
Integer Read-Only
The largest IP datagram that can be reassembled, i.e., the constant 4470.
2.4.2 IP Routing Table
The TCP/IP IP routing table contains the routing information for each route
currently known by the FN100. When adding a row, the entire row must be
specified, except for the following defaults:
• ipRouteDest is obtained from the row’s instance identifier.
• ipRouteMetric1 defaults to 0.
• ipRouteMetric2 defaults to sfadminStaticPreference.
• ipRouteMetric3 through ipRouteMetric5 default to -1.
• ipRouteNextHop is obtained from the row’s instance identifier.
• ipRouteType defaults to “direct” if ipRouteNextHop is not specified, or if
ipRouteNextHop is specified and it, combined with ipRouteMask, equals the
same network as that defined by ipRouteDest.
• ipRouteProto defaults to “netmgmt.”
• ipRouteMask defaults to the standard network class mask based on the row’s
instance identifier (except 255.255.255.255 is used if the row’s instance
identifier contains a non-zero host portion).
Parameters include the following variables.
ipRouteTable {ip 21}
Not-Accessible
A list of routing entries; one per route. An entry is keyed by an IP address
(ipRouteDest, defined below). If there are multiple entries for the same IP
address, then only the entry being used by the IP forwarding process is available
for SNMP access.
