Configuring the Serial Line Internet Protocol (SLIP)

Advanced SLIP configuration

Advanced configuration of SLIP may be performed using the Advanced Options available from the Network Configuration Manager.

Proxy ARP
If set to On, add a proxy entry for the IP address of the remote end of the SLIP link in the ARP table. This will allow other hosts on the local network to contact the remote system if its IP address belongs to the local subnet.

TCP/IP header compression
If set to On, TCP/IP header compression is enabled and the interface sends compressed packets. The remote end of the link must be willing to accept such packets.

Auto detect header compression
If set to On, the interface will attempt to detect compressed packets. If it does, it will respond with compressed packets.

Auto-detection has no effect if TCP/IP header compression is already configured on.

Hardware flow control
If set to On, use hardware flow control on the serial line.

ICMP packet suppression
If set to On, stop ICMP packets (such as those used for redirects, ping, traceroute, and router discovery) from passing through the interface.

Maximum transmission unit
Enter the size of the maximum transmission unit (MTU) in bytes.

The default MTU value is 296. Increasing this value may increase throughput as packets can contain more data. However, it may also decrease throughput if packets are routed through systems with lower MTU values, as each packet is split (fragmented) into smaller packets for transmission. You can experiment with this value to obtain the most desirable results.


NOTE: The suggested value for the MTU is 40 plus some power of 2. For example, the default value, 296, is 40 plus 2^8. Other possible values include 552, 1064, and 2088.

Debugging
If set to On, enable logging of SLIP debug messages about the state of the link to the system console.
