Resolved Caveats—Cisco IOS Release 12.0(29)S1
Conditions: This symptom is observed when the Cisco 10720 functions in a broadcast ARP storm
environment and when the length argument of the hold queue length in interface configuration
command is not the default of 75 packets for any interface of the router (for example, the length
argument is 2048).
Workaround: Revert the hold queue length in interface configuration command and the hold queue
length out interface configuration command to the default setting on all interfaces with non-default
hold queues.

Symptoms: A PXF buffer leak occurs on an L2TPv3 decapsulation router, which van be observed in
the output of the show hardware pxf cpu buffer command:
router#show hardware pxf cpu buffer
FP buffers
pool size # buffer available allocate failures low buffer drops
----------------------------------------------------------------------------

3 256 34072 34072 0 0
4 128 59934 59934 0 0
Depending on the packet size, the buffer leak can occur in different pools.
Conditions: The symptom is observed on a Cisco 10720 in the following two scenarios:
An MPLS-enabled interface is the network backbone for L2TPv3 tunnels.
An 802.1q interface is the network backbone for L2TPv3 tunnels and an input security ACL
with more than 400 lines is configured on the 802.1q backbone interface.
Workaround: There is no workaround.

Symptoms: When six queues are configured on an interface and some of the queues do not have
traffic, the bandwidth of those inactive queues should be given to other active queues (queues with
traffic) in proportion to their EIR (configured via bandwidth remaining). However, this is not the
case. The bandwidth is not proportionally given to all the queues.
Conditions: Configure a policy map that creates six queues in an interface.
Workaround: There is no workaround.
CSCeg11421
Symptoms: A Cisco 10720 crashes when you delete an IPv6 ACL.
Conditions: This symptom is observed when you delete the IPv6 ACL during the TurboACL
compilation.
Workaround: Wait for the ACL to be fully compiled before you delete it.
