1457516 QFX5110s switches port 51 has 1 led blinking amber
Product-Group=junos
One of the LEDs on port 51 on QFX5110s is blinking amber continuously. This caused by the PTP inadvertently access port 51 instead of limiting its access to only port 52 and 53. The fix is to correct the PTP process to only use port 52 and 53
PR Number Synopsis Category: Border Gateway Protocol
1487691 High CPU utilization might be observed when the outgoing BGP updates are sending slowly
Product-Group=junos
On all Junos platforms with the BGP routing protocols, the rpd process might go into a high CPU utilization causing slow network convergence. If a BGP peer is receiving and processing BGP updates slowly, this may cause the BGP output queue of the sending BGP peer to be full. When the queue is full it causes high CPU utilization of the BGP IO thread (bgpio, it is part of the rpd daemon) on the sending BGP peer. This defect could cause network-wide slow BGP network convergence. (See also https://kb.juniper.net/TSB17725)
