On QFX5230 and QFX5240 switches, configuring the
native-vlan-id
stanza on a trunk port results in traffic egressing as untagged for all the vlans. If this CLI is not configured, the correct vlan tags are sent for tagged traffic, however, access traffic arriving on the port is discarded. PR1827669 -
On the QFX5230 and QFX5240 platforms, host injected control protocol frames are accounted under the egress port's best-effort queue ( Q0 by default) even though they are sent on the network control queue. This is only a display issue of the show command output and does not affect the actual prioritization of traffic. PR1835046
When PFE is 100% busy with workloads, some show CLI commands timeout with an error message and some CLIs silently exit without any error. The following commands might return empty output when PFE is 100% busy:
-
show pfe filter hw
-
show pfe
-
show forwarding-options hash-key
-
show forwarding-options enhanced-hash-key
-
-
Junos OS Evolved Packet Forwarding Engine cores might be observed on doing configuration changes and restarting pfe process within a short period of time. PR1844123

For EVPN-VXLAN fabric, the base/from build for unified ISSU is 23.4X100-D20. System might go in a cold boot state if unified ISSU is done from a build prior to 23.4X100-D20 if the
set system packet-forwarding-options overlay
hierarchy is configured. PR1844692 -
In a large scaled VXLAN fabric involving more than 200 Vteps and more than 64K MACs, partition mode settings (set system forwarding-options overlay <> ") result in a Packet Forwarding Engine restart which results in large number of BD, VENH and flood NH delete events which takes time. Customer should include profile and partition mode settings in the default configuration itself instead of switching to and from baseline configuration to avoid this issue. PR1845230
