speciﬁed IP address and TCP port.

of inactivity.

Table 63: Expansion Port Conﬁguration 1

If you mark the Reject new connections check box, then the router rejects any other con-

nection attempt. This means that the router no longer supports multiple connections.

If you mark the Check TCP connection check box, the router veriﬁes the TCP connection.

Item Description

Keepalive Time Time after which the router veriﬁes the connection.

Keepalive Interval Length of time that the router waits on an answer.

Keepalive Probes Number of tests that the router performs.

Table 64: Expansion Port Conﬁguration 2

When you mark the Use CD as indicator of the TCP connection check box, the router uses

the carrier detection (CD) signal to verify the status of the TCP connection. The CD signal

veriﬁes that another device is connected to the other side of the cable.

CD Description

Active TCP connection is enabled

Nonactive TCP connection is disabled
