When a subscriber has subscribed for a service, service session accounting records

always contains a default Acct-Terminate-Cause value of 10. This value remains
unchanged even after you use the terminate-code command to configure a custom
mapping between application terminate reasons and RADIUS
Acct-Terminate-Cause attributes. [Defect ID 181043]
You cannot use a configuration script to boot the E320 router. [Defect ID 80304]

If you hot swap an IOA and then remove it again before that IOA's OK or FAIL LED is

illuminated, the associated line module can reset. [Defect ID 177313/177267]
Work-around: Ensure that you firmly insert the IOA into the chassis when you hot
swap IOAs. Do not attempt a second hot swap of an IOA that has not indicated that it
completed the first hot swap cycle. You can remove the IOA when either its OK or
FAIL LED is illuminated.
If your router is in Manual Commit mode, then you must issue the write memory

command before you perform an SRP module switch or a manual reload. You must
do this even when you have made no changes to the system configuration and the
file systems are synchronized. [Defect ID 44469]
The SRP module resets in any of the following circumstances on an E320 router that

has a line module configured with 5000 ANCP adjacencies: [Defect ID 176916]
 When you issue the issu initialization command from the console and then
reload the line module from a Telnet session.
 When the client that has the 5000 ANCP clients resets or an intermediate switch
resets.
 When you reload the line module.
Unified ISSU is not supported with 8000 bridged Ethernet interfaces on an

OC3/STM1 GE/FE ATM line module. [Defect ID 178811/178797/
179547]
ATM line modules might reset after a unified ISSU when you attempt to add memory

to a VLAN subinterface in a large bridged Ethernet configuration. [Defect ID 178798]
Under certain conditions, a unified ISSU from JunosE Release 9.2.0p1-0 to the current

release fails, and causes the SRP module and the ES2 4G LM to reset. [Defect ID
179975]
During the unified ISSU operation, if you modify the router configuration after the

initialization phase of the process is completed and before you issue the issu start
command to commence the upgrade phase of the unified ISSU process, the unified
ISSU procedure completes successfully and the stateful SRP switchover process
begins to synchronize between the active and standby SRP modules. When the
synchronization process is in progress, the standby SRP module reloads for the
second time. After the second reload of the standby SRP module ends, the
synchronization process also ends properly.
