JunosE 11.3.0 Release Notes
54 Known Problems and Limitations
Although the standby SRP module reloads for the second time when it is
synchronized with the upgraded release, normal router operations, such as handling
of subscriber sessions and forwarding of traffic, remain unaffected. [Defect ID
185517]
When any of the subsystems is excluded for a JunosE release, a unified ISSU to that

release fails to apply conversion code to all of the line modules. As a result, the line
modules reset when they come up with that release. [Defect ID 179595]
Work-around: To prevent the exclusion of a subsystem file from the release, do the
following before you upgrade to a new JunosE release that supports unified ISSU:
1. Issue the show subsystems file fileName.rel command, where fileName is the
name of the software release file, to determine whether any of the subsystem
files are excluded from the release.
2. For each subsystem file that is excluded, issue the no exclude-subsystem
subsystemName command to remove the exclusion for the specified
subsystem file.
If you copied the software release to the router before removing the subsystem file
from the exclusion list, you must copy the release to the router again to ensure that
all subsystem files are included in the release.
