Conﬁguration Parameters

syslog_port

This Model 5390 parameter routes syslog messages to an asynchronous port where messages are

time-and-date stamped. Valid options are 0 through the Model 5390 port count. A zero value indicates

syslogging takes place over the network; a nonzero value indicates the port to which syslog messages

are sent. The default is 0.

A sample message looks like this:

Thu May 19 10:44:55 <190>cli[354]: Port Begin:1:CLI:::[local]

This T1 parameter stores installation information from the service provider, such as a telephone

number to call should the network go down. This parameter is limited to a 120-byte string of printable

ASCII characters.

tcp_keepalive (Model 5390)

This Model 5390 parameter speciﬁes the length of time a TCP connection must be idle before the

Model 5390 server sends keep-alive messages. A keep-alive message contains no data but solicits

an acknowledgment from the other end of a connection to determine whether the connection is still

active. If the recipient does not acknowledge the message after eight retries, the Model 5390 server

drops the connection. Valid values are 0 through 255 (minutes). A value of 0 sets the keep-alive time

to 120 minutes, which is the default; a value of 255 disables the keep-alive mechanism. The

tcp_keepalive parameters for serial-line ports overrides this parameter for those individual ports.

This asynchronous port parameter speciﬁes the length of time a TCP connection must be idle on

one or more speciﬁc asynchronous ports. This parameter overrides the Model 5390 tcp_keepalive

parameter for connections to the host from adaptive, CLI, and dedicated ports, and for connections

from the host to slave and adaptive ports. Valid values are 0 to 255 (minutes). The default is 0.

Entering a zero speciﬁes that the keep-alive time is the value set in tcp_keepalive; entering 255

disables the keep-alive mechanism for the port.
