Administration Commands

define_sdlc_ls

nve_poll_timer

Timeout required before an adjacent secondary station (which has previously been removed from the polling list because it has no data to send) is reinserted into the polling list. The timer is specified in milliseconds.

nve_poll_timer_retry

Number of times a station is removed from the polling list on the normal poll timer (specified on the nve_poll_timer parameter) before SNAplus2 switches to using the slow negative poll timer (specified on the nve_poll_timer2 parameter).

Specify a value in the range 1–65,535. A value of 65,535 indicates an unlimited retry count. A value of 1 indicates that the switch to the slow poll should be made after the timer expires the first time.

nve_poll_timer2

The slow negative poll timer in milliseconds. When the count specified by the nve_poll_timer_retry parameter expires, SNAplus2 continues to poll using this timer. This prevents leased multipoint links from being flooded by poll frames for idle stations.

nve_poll_timer_retry2

Number of times a station is removed from the polling list on the slow poll cycle before the link is assumed to have failed. Specify a value in the range 1–65,535. This value is normally set to 65,535, indicating infinite retry.

no_resp_timer

The maximum amount of time a primary station waits (after having sent a frame with a poll bit) for a response frame before trying to poll another station. This timer is restarted when a frame without an F-bit is received and stopped only when a frame with an F-bit is received. The timeout should be set to a value not less than twice the transmission time for the longest I-frame plus adjacent station frame processing time.

The timer is specified in milliseconds.

no_resp_timer_retry

Number of times an adjacent secondary station is allowed to fail to respond before the primary station as- sumes that the link has failed.

Specify a value in the range 1–65,535. A value of 65,535 indicates an unlimited retry count. A value of 1 indicates that the link is assumed to have failed after the first timer expires.

rem_busy_timer

Time allowed for an adjacent secondary station to be in a receive not ready (RNR) condition. This parameter is used in conjunction with the value of the rem_busy_timer_retry parameter to provide the overall time before the link is assumed to have failed. The timer is specified in milliseconds.

rem_busy_timer_retry

This parameter is used in conjunction with the value of the rem_busy_timer parameter to provide the overall timeout before the link is assumed to have failed.

Specify a value in the range 1–65,535. A value of 65,535 is used to indicate an unlimited retry count. A value of 1 indicates that the link is assumed to have failed after the timer expires the first time.

rr_timer

The amount of time in milliseconds to wait before turning the poll bit around when the SDLC component has no work to do.

This parameter may be set to 0 (zero) to indicate an immediate turn-around, or to a nonzero value if the immediate turn-around causes hardware problems on the link. Higher values can also be used to optimize link usage because often SNAplus2 will generate data in response to the data contained in an I-frame carrying the poll bit; the pause allows the data to be received and processed.
