Configuring DLSw Services

A-22

304233-A Rev. 00

Parameter: KeepAlive Time (sec)

Path:

Configuration Manager > Protocols > DLSw > Advanced > Global

Default: 60

Range: 0 to 2147483647

Function: The TCP KeepAlive Time parameter specifies how often the router sends a

signal to the peer router to check that the peer router is working correctly and

can receive messages. You enable the parameter by specifying a nonzero value.

When a keepalive packet goes unacknowledged by the remote peer,

retransmission begins at the local peer router. You should tune the keepalive

interval based on the total time it takes to send and receive acknowledgment

from the remote peer.

Since keepalive packets are sent only on idle lines, increasing the keepalive

interval may decrease the cost of an idle network. In busy networks, the

keepalive interval is not necessary. Frequent traffic for TCP transmission

performs the same function as a keepalive setting.

Instructions: Enter a value appropriate for the network in the range 0 to 2147483647 seconds.

We recommend that you set this parameter to the same value on the peer router

to maintain synchronization. The default is 60 seconds.

Type the number of seconds that you want for the keepalive time interval, or

type 0 to disable the keepalive feature.

MIB Object ID: 1.3.6.1.4.1.18.3.5.1.5.1.16

Parameter: KeepAlive Retry Timer

Path:

Configuration Manager > Protocols > DLSw > Advanced > Global

Default: 60

Range: 0 to 600

Function: The Keepalive Retry Timer parameter specifies the maximum time (in seconds)

between successive retransmissions of keepalive packets. If an acknowledgment

is not received by the local peer router within the TCP keepalive retry timeout,

the local peer router retransmits the keepalive packet. The router continues to

retransmit keepalive packets at every TCP keepalive retry timeout until it

receives an acknowledgment from the remote peer, or until TCP reaches the

keepalive retries setting.

Instructions: Enter a value in the range 0 to 600 seconds.

MIB Object ID: 1.3.6.1.4.1.18.3.5.1.5.1.30
