IBM SC30-3681-08 manual Valid values 0 to Default value Example, Link modulo 8 or, Link name

Con®guring SDLC Interfaces

delay is not sufficient to allow a response from the 2210 to another device. You cannot set leading ¯ags to a non-zero value if inter-framedelay is 0.

Valid values: 0 to 15

Default value: 0

Example:

set link leading flags

Leading flag counter [0]?

link modulo 8 or 128

Speci®es the sequence number range to use on the link: MOD 8 (0-7) or MOD 128 (0 - 127). Default is 8.

Note: When you change this value, the window sizes become invalid. Use the set station command to change the receive window and transmit window sizes. Valid window sizes for mod 8 are 0 through 7; for mod 128 they are 8 through 127.

Also, at connection start-up, an SNRME rather than a SNRM is used and supervisory frame headers are expanded by an additional byte.

link name

Establishes a character string for the link that you are con®guring. This parameter is for informational purposes only.

Example:

set link name

Enter link name: [LINK_0]?

link poll delay

Con®gures the time delay between each poll that is sent over the interface.

Example:

set link poll delay

Enter delay between polls [0.2]?

link poll retry

Con®gures the number of times the interface retries to poll the secondary SDLC link station before it closes the connection.

Example:

set link poll retry

Enter poll retry count (0 = forever) [10]?

link poll timeout

Con®gures the amount of time the interface waits for a poll response before timing out.

Example:

set link poll timeout

Enter poll timeout [2.0]?

link role primary or secondary or negotiable

Con®gures the interface as an SDLC primary, secondary, or negotiable link station (default is primary).

Notes:

1.For DLSw, negotiable uses X©FF© (broadcast address) for the initial poll.

When using broadcast address to negotiate the role, the link uses a default SDLC con®guration.

When primary is the link role, the link performs an initial poll to a speci®c address.
