JUNOSe 11.1.0 Release Notes
IP
The ES2 4G LM can reset during a unified ISSU after you issue the issu start
command on a router configured with 8000 dynamic VCs and 8000
packet-triggered dynamic subscriber interfaces. [Defect ID 86761]
If you have a large configuration on a hybrid module combination (OC3/STM-1
GE/FE line module with the OC3-2 GE APS I/O module), boot from NVS, and
issue the slot erase command before booting has completed, the line module
resets. [Defect ID 64104]
Work-around: To recover from the error, issue the slot reload command
anytime after the module begins to reset.
Deleting a VRF with 32,000 static subscriber interfaces fails to complete.
[Defect ID 82670]
Work-around: Use a macro to delete all static subscriber interfaces before you
delete a VRF.
IP interface statistics become inconsistent when a slot is reset, because some
traffic (such as control traffic) might be destined for the SRP module and is
therefore counted elsewhere. [Defect ID 26697]
The ip route permanent command does not work properly. [Defect ID 34303]
Work-around: Issue the ip alwaysup command to prevent the route from
being removed from the IP routing table after the interface is shut down.
Traffic statistics for dynamic subscriber interfaces associated with Mobile IP
subscribers are not maintained as the subscribers move between Mobile IP
nodes. Consequently the reported interface statistics are only the values
accumulated since the last time a mobile node moved. [Defect ID 174509]
When a router configured with PIM on a virtual router undergoes multiple
warm restarts, the router subsequently hangs when an IP profile is configured.
[Defect ID 176470]
Logical port 20 on the ES2-S3 GE-20 IOA is reserved for the hardware multicast
packet replication feature. Logical port 20 and the hardware multicast
replication feature are not supported on the ES2-S3 GE-20 IOA in this release.
[Defect ID 84727]
When you change the demultiplexer type on a primary interface that has 1024
demultiplexer table entries, the ICC ping threshold times out due to the
removal of the old entries and the addition of the new ones. [Defect ID
182218]
After an SRP stateful switchover completes on an ERX1410 router configured
with a single VPN routing and forwarding instance (VRF) and Network Address
Translation (NAT), the SRP module that becomes active after the switchover
resets. [Defect ID 180058]
