NOTE: In rare cases, EX3300 switches running a Junos OS release prior to
Release 11.3R4 or Release 11.4R2 might experience some traffic loss or a link
failure as a result of non-user-configurable settings that are not optimized.
To resolve this issue, upgrade to one of the following Junos OS releases:
•
Junos OS Release 11.3—R4 and later
•
Junos OS Release 11.4—R2 and later
•
Junos OS Release 12.1—R1 and later
