applied to the new logical interface. To resolve this problem, deactivate and
activate the interface portion of the class-of-service configuration. [PR/485872]

On an Ichip-based platform for strict high priority queue (SHQ), the buffer size
allocated by the Packet Forwarding Engine is capped by the tx-rate. If the tx-rate
is configured to a very small value or is not configured, and is automatically
allotted a zero or a very small remaining value; the queue is also allotted a
proportionately small delay buffer. This can sometimes lead to Red and Tail
drops on the SHQ when there is a burst of traffic (with a certain traffic pattern)
on it. As a workaround, configure a nominal tx-rate value (5 percent) for the
SHQ. [PR/509513]
■
On M Series and T Series routers, the forwarding class information is lost when
the packet enters the GRE tunnel with clear-dont-fragment-bit enabled.
Additionally, on an Enhanced FPC or M120 FEB, the packet is also likely to be
dropped if it is classified to a packet loss priority (PLP) other than low.

Forwarding and Sampling
■
Policers cannot be modified after a system upgrade due to a flaw in the parser
routine. This error occurs when the current item is deleted and the parser cannot
proceed to the next item. With the fix, the routine in the forwarding process
(dwfd) has been modified so that the next item in the object tree is fetched before
the current object is parsed. [PR/433418]

Under rare circumstances, if the filter is changed while a counter query is in
progress and the system is under heavy load, the system may crash. [PR/447033]
■
The numerical values configured for the ip-options match criteria on a firewall
filter matches any ip-options no matter what is specified. [PR/516778]
High Availability
■
A problem occurs during graceful Routing Engine switchover (GRES) when a
static route pointing to a private interface such as fxp0 is created using the passive
retain option. It is recommended to not use the
passive
option along with the
static route on the private interface. [PR/412746]
■
The SSH keys are not in sync between the master and backup Routing Engine
when SSH is enabled after a graceful Routing Engine switchover (GRES).

When an ISSU upgrade is performed to or from JUNOS Releases 9.6R3 or 10.0R2,
the logical interface and logical interface sets that have traffic control profiles
configured on them will be affected. [PR/491834]

On a 2-port OC12 ATM2 IQ interface, the total virtual path (VP) downtime might
not display correctly in the
show interfaces
command output. [PR/27128]
■
If you configure IS-IS, MPLS, and graceful Routing Engine switchover (GRES) and
a switchover event occurs, the routing platform might end the PPP IP Control
