1455722	ACX5048 snmp polling will stalled after the link flap/ sfp replacement and ACX_COS_HALP(acx_cos_gport_sched_set_strict_priority:987): Failed to detach logs will be seen Product-Group=junos	When inserting a SFP, the lowest ifd index available is assigned to the new interface created. During this sfp attach, an ifd-halp entry is also created in cos table for the interface. When SFPs are swapped and SFPs get their IFD index assigned interchanged as that of their old IFDs, issue is observed. As per PFE, the bcm port for the interface remains the same while IFD alone changes when removed and inserted. Hence while creating an ifd-entry for the interface in cos table, it is checked for any old entry still present for same bcm port. But the check done to validate for any old entry is improper. It does not check whether the old ifd index present is still for same bcm port. Due to this check missing, a valid ifd-entry of some other interface is getting deleted in cos table. Introduced the additional validation to ensure the old ifd index of the interface is still for same bcm port. Deleting of old ifd-entry is done only if bcm port of current entry and old ifd entry are same. Also added in existing debug message to display the ifd index which is getting deleted.

1473351	Removing cluster from BGP group might cause prolonged convergence time Product-Group=junos	Cluster removal from BGP group might lead to a state where each subsequent change to BGP configuration will trigger import policy reevaluation causing prolonged convergence time of several minutes. This might result in a traffic loss.
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)

In order to avoid this scenario we can configure in JUNOS the following values to the Kernel Routing Table IO: set routing-options krt-io-options work-queue-length high-threshold 250 set routing-options krt-io-options work-queue-length low-threshold 200 set routing-options krt-io-options tx-bulk-count 10 Important Notes: The above commands require RPD restart to take effect. When the "interface down" happens, IGP and BGP protocols perform RIB route-change. The IGP change is placed into a high priority queue and the exterior route change is placed into a low priority queue. For 64-bit systems, RPD workqueue size is 10000 and bulk count is 30. As a result, the head of line blocking for the IGP route change could potentially be up to 300000 rtsock requests, which causes the delay in FIB convergence for that particular prefix when the interface comes up immediately after interface down.
