Server User Manual

Adding/Editing Users
206 IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0
TCP Port When the User Service is Telnet, this is the target port number. The default
value will change based on the type of
Service selected; the most common
known port numbers are used as the default values.
IPv4 Address Used for User Service PPP or SLIP, sets the IP address of the remote user.
Enter the address in dot decimal notation as follows:
z n.n.n.n—(where n is a number) Enter the IP address of your choice. This
IP address will then be used in preference to the
Remote IP Address set
for a line.
The following IP addresses have a special meaning:
z 255.255.255.254—The IOLAN will use the Remote IP Address set in the
PPP settings for the serial port that this user is connecting to.
z 255.255.255.255—When the User Service is PPP, the IOLAN will allow
the remote machine to specify its IP address (overriding the IP address
negotiation value configured in the
PPP settings).
z 255.255.255.255—When the User Service is SLIP, the IOLAN will use
the
Remote IP Address set for the line (no negotiation).
Default: 255.255.255.254
IPv4 Subnet Mask If the remote user is on a subnet, enter the network’s subnet mask. For
example, a subnet mask of 255.255.0.0.
IPv6 Interface
Indentifier
Used for User Service PPP, sets the IPv6 address of the remote user. Enter the
address in IPv6 format.
Field Format: The first 64 bits of the Interface Identifier must be zero,
therefore, ::abcd:abcd:abcd:abcd is the expected format.
MTU Used for User Service PPP or SLIP, specifies the maximum size of packets, in
bytes, being transferred across the link. On noisy links it might be preferable to
fragment large packets being transferred over the link, since there will a be
quicker recovery from errors.
Data Options:
z PPP—MTU will be the maximum size of packets that the IOLAN will
negotiate for this port. This value is negotiated between the two ends of
the link.
z SLIP—MTU will be the maximum size of packets being sent by the
IOLAN.
The
User MTU value will override the MTU/MRU values set for a Serial Port.
Range: PPP: 64-1500 bytes, SLIP: 256-1006 bytes
Default: PPP is 1500 bytes, SLIP is 256 bytes
Routing Determines the routing mode used for RIP packets on the PPP and SLIP
interfaces. Values are:
z None—RIP packets are neither received nor sent by the IOLAN.
z Send—RIP packets can only be sent by the IOLAN.
z Listen—RIP packets can only be received by the IOLAN.
z Send and Listen—RIP packets are sent and received by the IOLAN.
Default: None
