memory debug leak on the console while show memory detailed process iosd debug leaks is

• Traffic is dropped on a particular tx-queue of an EtherChannel member interfacere configured with
a queuing policy. However, it will still appear in an egress span session of the EtherChannel.
The show platform software interface tx-queue command will display an incorrect number of
configured queues (compare to EtherChannel members that are not dropping traffic).
Workaround: Enter shut then no shut on the port. CSCua66962
• On a switch running Cisco XE 3.2.4SG or 3.3.0SG with 4648* or 4748* linecards with PoE, a single
port on a linecard fails to link up, usually after flapping its link frequently.
Workaround: Enter shut then no shut on the port. CSCtz94862
• On a switch running Cisco XE 3.2.4SG or 3.3.0SG on 4648* or 4748* linecards with PoE, the PoE
device will not power up on a single port, but will work on other ports on the same linecard.
Workarounds:
–
Connect a non-PoE device to the port
–
Enter shut then no shut on the port. CSCua63562
• While running flexible netflow, the extended VLAN range of 1024-4000 is not observed in the

interfaces on the module, a crash may occur when you remove a line card.

following conditions apply:
–
A switchport is configured with both of the following:
authentication event server dead action authorize...
authentication event server alive action reinitalize
–
The RADIUS server was down previously, and a port without traffic (for example: a hub with
no devices attached) was authorized into the inaccessible authentication bypass (IAB) VLAN
without an associated MAC address.
