Link failure Link reset failed due to timeout
Example 4-23 shows this message. It indicates that the interface transmitted a LR primitive but did not receive a LRR back within 100ms. This is likely due to the interface being at zero remaining-Tx-B2B-credits for an extended time (1 or 1.5 seconds). Hence, it initiates Credit Loss Recovery by transmitting an LR. Since LR is transmitted during normal link initialization it could also be a non-congestion problem during link activation. Under normal situations, this should exactly correlate to instances of Credit Loss Recovery by LR. If the neighbor is also an MDS it may not have returned the LRR due to severe ingress congestion. If so, see the earlier Syslog message indicating ‘Link failure Link Reset failed nonempty recv queue’. 例 4-23 显示了这条信息。它表明接口传输了 LR 原始信息，但在 100ms 内没有收到 LRR 返回。这可能是由于接口在较长时间（1 或 1.5 秒）内剩余 Tx-B2B 信用点为零。因此，它会通过传输 LR 来启动信用损失恢复。由于 LR 是在正常链路初始化期间传输的，因此也可能是链路激活期间的非拥塞问题。在正常情况下，这应与通过 LR 恢复信用损失的实例完全相关。如果邻居也是 MDS，它可能因入口严重拥塞而没有返回 LRR。如果是这样，请参阅之前的系统日志消息，其中显示 "链路故障 链路重置失败 非空重置队列"。
