Configuring VISM Features

Step 6 Type the cnfsesmaxseg command, session-num and seg-size argument values, and press Enter to

configure the maximum segment size VISM can receive after sending a SYN message. Specify the arguments

with the following values:

•session-num: Type the value entered for the session-num argument in Step 4.

•seg-size (defined in octets): In the range from 30 to 65535

Step 7 Type the cnfsesmaxwindow command, session-num and window-size argument values, and press Enter

to configure t he maximum number of segments that can be sent without getting an acknowledgment for a

specific RUDP session. Specify the arguments with t he following val ues:

•session-num: Type the value entered for the session-num argument in Step 4.

•window-size: In the range from 1 to 64

Step 8 Type the cnfsesnullsegtmout command, session-num and null-seg-tout argument values, and press

Enter to configur e the amount of idle time before sending a null segment. Specify the argum ents with th e

following va l ues:

•session-num: Type the value entered for the session-num argument in Step 4.

•null-seg-tout (defined in milliseconds): In the range from 0 to 65535

Step 9 Type the cnfsesoutofseq command, session-num and max-seq-pkts argument values, and press Enter to

configure the maximum number of out-of-sequence packets that will be accumulated before sending an

EACK packet. Specify the arguments with the following values:

•session-num: Type the value entered for the session-num argument in Step 4.

•max-seq-pkts: In the range from 0 to 255.

Note If you specify 0 for the max-seq-pkts argument, a DACK message is sent immediately

upon receiving an out-of-sequence packet.

Step 10 Type the cnfsesport command, session-num, local-port-num, and remote-port-num argument values,

and press Enter to configure the local (VISM end) and remote (call agent en d) port numbers for a session

number. Specify the arguments with the following values:

•session-num: Type the value entered for the session-num argument in Step 4.

•local-port-num: In the range from 1124 to 65535

•remote-p ort-num : In the range from 1124 to 65535

This command allows the user to configure the local and remote port numbers.

Step 11 Type the cnfsesretrans command, session-num, unack-timeout, and max-ses-retrans argument values,

and press Enter to configure the retransmission of unacknowledged packet timeout value and the maximum

number of consecutive retransmission attempts before the connection is considered failed. Specify the

arguments with the following values:

•session-num: Type the value entered for the session-num argument in Step 4.

•unack-timeout (in milliseconds): In the range from 100 to 65535

•max-ses-retrans: In the range from 0 to 255

Step 12 Type the cnfsesstatetmout command, session-num and tstate-tout argument values, and press Enter to

configure the amount of time VISM waits for the transfer state before executing an auto reset. Specify the

arguments with the following values:

•session-num: Type the value entered for the session-num argument in Step 4.

•tstate-tout (in millisecond s): In the range from 0 to 65535
