PPPoE
z
The E Series router erroneously accepts a PADI with a payload length of 0 instead of
rejecting it and incrementing the PPPoE Invalid PAD packet length counter. [Defect
ID 48356]
QoS
z
You cannot paste a
load-rebalance
command string that uses the percent option
into a console or Telnet session from
show configuration
output because the output
displays the % sign rather than the
percent
keyword that was submitted with the
command and the percent sign is not recognized by the CLI. [Defect ID 81705]
z
The compound shared shaping feature does not work properly on egress forwarding
ASIC 2 (EFA2)-based ATM line modules when the shared shaper is queue-controlled
as opposed to node-controlled. In a node-controlled configuration, in which you
configure the shared-shaping rate on the best-effort scheduler node for the logical
interface, integration of the EFA2 and ATM segmentation and reassembly (SAR)
schedulers functions properly. However, in a queue-controlled configuration, in which
you configure the shared-shaping rate on the best-effort queue for the logical
interface, integration of the EFA2 and ATM SAR schedulers does not function
properly. [Defect ID 69167]
Work-around
: Use node-controlled compound shared shaping configured on the
best-effort scheduler node with EFA2-based ATM line modules.
z
The CLI erroneously enables you to configure a QoS profile with the
ethernet node
group
command. [Defect ID 80861]
z
The dynamic shaping rate calculated by the simple shared shaper can vary because
of the variation in the enqueue rate of the constituent queues. Even when the offered
load is constant, the mechanism that calculates the enqueue rate introduces a slight
variation, introducing a slight variation in the calculated dynamic shaping rate.
[Defect ID 80938]
z
On a router that has both an ES2 10G LM and an ES2 4G LM installed, the byte count
reported by the
show fabric-queue egress-slot
command is incorrect. The reported
packet count is correct. [Defect ID 80965]
z
PPP sessions may be dropped if you change the shaping rate in a QoS profile that
affects thousands of circuits while QoS traffic affected by the profile is being
forwarded. [Defect ID 82950]
Work-around
: Do not change the shaping rate in a QoS profile that affects
thousands of circuits while QoS traffic is using the profile.
z
When QoS resources such as failure nodes and statistics bins are exhausted because
of insufficient memory available on the line module, the failures are properly logged,
but additional log messages are generated every 10 minutes that report zero failures.
[Defect ID 85105]
z
The
no qos-parameter-define definition
command does not delete the specified
QoS parameter definition. [Defect ID 176844]
Work-around
: Remove the interface and add the desired QoS parameters when you
re-create the interface instead of deleting the definition.
