General Routing

  • On QFX10002, QFX10008, and QFX10016 switches, the following error message is observed during specific steps while clearing and loading the scaled configuration again: PRDS_SLU_SAL:jprds_slu_sal_update_lrncnt(),1379: jprds_slu_sal_update_lrncnt call failed. This issue is observed in a scaled setup with scaled VLANS and traffic flowing through all VLANS. If the configuration is cleared and loaded again using the below steps: load override <base-config> rollback 1 commit Then the base configuration is loaded, all leaned MACs are aged out and the MAC entries are marked as invalid. Aging thread scans and finds SMAC ref bit transition for cleared MAC entries and gets added to a stale MAC software table. In a scaled setup where 2000 MACs are learned over a port, not all MACs are cleared at one hardware trigger. This happens in a batch of 256 entries in a MAC table at a time as per the design of the QFX10000 lines of switches. In the meantime, it is expected that IFBD on which the MACs were learned is deleted. This is the reason why Lport+IFL mapping is not found while clearing such MACs and throws an error. PR1522852

  • When TISSU upgrade is done from 22.4 release onwards, the box come up as backup Routing Engine. Work-around:- To make is primary following command needs to be run again. sysctl -w hw.lc.issuboot=0 sleep 10 sysctl -w hw.re.issu_state=0 sleep 10 sysctl -w hw.re.tissu=0 sleep 10 sysctl -w hw.product.pvi.config.chasd.no_re_status_on_backup=1 sleep 60PR1703229

  • Disable the VME interfaces or have the default route added properly from the shell script for the connectivity with the ZTP server to work. PR1743222

  • On all Junos OS platforms, due to timing issues the PFE (Packet Forwarding Engine) /PICs (Physical Interface Card) will be slow and services will face slowness issue and error message: Minor potential slow peers are: X will be seen. This is rare timing issue. PR1747077

Interfaces and Chassis

  • The LAG (Link Aggregation Group) member links might flap on all Junos OS platforms except MX when the configuration of any interface is changed or modified. The flap is not seen always. PR1679952
