SLIP/PPP Problems

Verify SLIP Host Address
If you are unable to connect using the SLIP protocol, enter the following command.
Substitute the number of the port for 1:
Local> SHOW PORT 1 SLIP
Port 1: Development Server: MMS
Host Address: 83.62.18.102 MTU: 1006
Header Compression: Disabled Compression States 16
Verify that the SLIP Host Address is defined and valid. The Internet address for the SLIP
host must be unique on the subnet and have the same subnet identifier as the access server.
For example, if the access server Internet address is 83.62.18.101 and the subnet mask is
255.255.255.0, the subnet identifier is 83.62.18.0. Therefore, the SLIP host address must
be 83.62.18.nn, where nn is any number between 1 and 254, except 101 (access server
Internet address).
For more information on configuring and managing SLIP ports, refer to the Network
Access Software Management Guide.
Verify Maximum Transmission Unit (MTU)
To determine the MTU size, enter the following command. Substitute the number of the
port for 1:
Local> SHOW PORT 1 SLIP
Port 1: Development Server: MMS
Host Address: 83.62.18.102 MTU: 1006
Header Compression: Disabled Compression States 16
The MTU characteristic allows access server compatibility with SLIP host
implementations that have fixed MTU values other than 1006 bytes. The TCP maximum
segment size (MSS) announced by the SLIP host at the time of a TCP connection is
normally based on the MTU of the network connection.
Many implementations use an MTU of 296 with CSLIP.
