Resolved Caveats
Cisco IOS Caveats Resolved in Cisco IOS Release 12.2(53)SE
• CSCsj68446
The Network Time Protocol (NTP) might not synchronize when the switch is configured as an NTP
client. These are the two possible workarounds:
– Enter the no ntp global configuration command twice.
– Reconfigure NTP on the port. For more information, see the “Configuring NTP” section of the
“Administering the Switch” chapter in the software configuration guide.
• CSCsv92937
When a blade server starts, the switch internal interface might flap due to the network interface card
(NIC) driver. In Cisco IOS Release 12.2(46)SE and earlier, the port might enter the error-disabled
state.
The workaround is to enter the errdisable max flap 10 time 10 global configuration command in
Cisco IOS Release 12.2(46)SE and earlier. In Cisco IOS Release 12.2(50)SE and later, the switch
no longer detects link flapping on the internal interfaces.
• CSCsx29696
On a switch running Cisco IOS Release 12.2(35)SE or later, connectivity issues might occur with
these messages:
%SUPQ-4-CPUHB_RECV_STARVE: Still seeing receive queue stuck after throttling
• CSCsy14568
When a switch port rejoins a cross-stack EtherChannel after the switch restarts, packets might be
dropped for a longer than expected time.
There is no workaround.
• CSCsz18634
On a switch running Cisco IOS release 12.2(46)SE, the output of the show interfaces privileged
EXEC command shows 0 packets for port channel input and output rates.
The workaround is to reload the switch by entering the reload privileged EXEC command.
• CSCtc02635
On switches running Cisco IOS Release 12.2(50)SE3 running MAC authentication bypass with
multidomain authentication (MDA), IP phones connected to a port might not be able to regain
network connectivity in the VOICE domain if the session times out and all RADIUS servers are
unreachable.
There is no workaround.
• CSCtc16848
The output of the show inventory user EXEC command sometimes does not display all of the
connected SFP modules. The EntitityMIB does not report these SFP modules.
This occurs intermittently on the 3560-48TS, C3560-48PS, and C3560G-48PS switches. There is no
workaround.
• CSCtc20603
If IEEE 802.1Q native VLAN tagging is enabled on a switch, PDUs sent from an EtherChannel in
LACP mode are tagged.
There is no workaround.
