This parameter specifies the length of time that the module may wait for all the fragments of a fragmented IP message to be received for reassembly. If they are not received within the specified time, the datagram is discarded. Note that datagram reassembly takes place at the destination of a datagram only.
∙Proxy ARP
If the module receives an ARP request for a host whose network or subnetwork address is assigned to one of its ports or if the module knows a route to the host, the module sends an ARP reply containing its own MAC address. Subsequently, all the packets directed to that host will be sent to the Multiprotocol Interconnect module which will in turn forward them to the correct destination.
∙Source Quench
This parameter specifies if the module generates ICMP source quench messages. These messages are sent to hosts, requesting them to reduce their data transmission rate.
∙Redirect
This parameter specifies if the module generates ICMP redirect messages. These messages are sent when the Multiprotocol Interconnect module recognizes that the sender of the IP packet is not using the optimal route to the destination. These messages are sent to the source of the frame, informing it of the faster route. The Multiprotocol Interconnect module processes received ICMP redirect messages and adds the routes to its IP routing table.
∙ICMP tx Rate
∙
∙
This parameter controls the rate at which ICMP messages are generated.
Hash Size
This parameter controls the hash size for the IP routing table.
Default TTL
This parameter specifies the value that is inserted into the
6.Enable IP routing on each port which is to perform IP routing. To do so, select IP Port Parameters from the IP Menu. An example of the IP port parameter panel is shown in Figure 164 on page 283.
