Open and Resolved Caveats in Software Release 5.3(1a)CSX
• A QoS IP ACL can contain nine ACEs that use port operator parameters. If you attempt to add a
tenth QoS IP ACE that uses a port operator parameter to an ACL, the following incorrect message
is displayed:
Cannot configure more than 10 logical operators (gt, lt, eq, neq, range) in an IP ACL.
The message errors are that it should state 9 instead of 10 operators and should not include “eq”
in the logical operator’s list. (CSCdm88490)
• Occasionally replacing an existing QoS ACL might fail with a Cannot configure more than 10
logical operators message when there are less than 10 logical operators in the new ACL. To
workaround this problem, enter a clear qos acl map command to delete the old ACL and then
create the new ACL. (CSCdm88538)
• When two MSFC modules are configured for HSRP and are configured as SPAN or RSPAN
source ports, the ingress traffic to the MSFC might not be mirrored to the destination port after
HSRP switchover or switchover to the redundant supervisor engine and MSFC. To workaround
the problem, enter the set span or set rspan command again. (CSCdm88732)
• After bridged microflow policing has been enabled and QoS has applied microflow policing rules
to bridged traffic in some VLANs, if you then disable bridged microflow policing, QoS continues
to apply microflow policing rules to bridged traffic in those VLANs until the switch is reset.
(CSCdm88933)
• The syntax of the clear security acl map command supports entry of a single VLAN number.
Entering a clear security acl map command with a range of VLANs generates an incorrect
“Invalid ACL Name” message. (CSCdm89538)
• The usage display for the clear qos acl map command is:
Usage: clear qos acl map <acl_name> <mod_num/port_num|vlan>
clear qos acl map <acl_name|mod_num/port_num|vlan|all>
The second syntax form fails when entered with multiple port numbers or multiple VLAN
numbers. (CSCdm89542)
• Occasionally, after being turned off and back on several times, switches configured as VTP
clients stop accepting VTP updates. (CSCdm90300)
• Use the QoS strict-priority queues only for your highest-priority traffic. The strict-priority queues
are designed to accommodate only a limited volume of traffic. In switches with Supervisor
Engine WS-X6K-SUP1-2GE, if you overload the strict-priority-queues, the supervisor engine
cannot service the standard queues. (CSCdm90683)
• When protocol filtering is enabled, Multicast Multilayer Switching (MMLS) does not work. To
use MMLS, do not enable protocol filtering. (CSCdm91222)
Resolved Caveats in Software Release 5.3(1a)CSX
This section describes resolved caveats in supervisor engine software release 5.3(1a)CSX:
• In some cases, you cannot remove a UGHD (up, gateway, host, dynamic) route from the switch
IP routing table. This problem is resolved in software release 5.3(1a)CSX. (CSCdk14130)
• Configuring an ISL trunk on a root bridge switch with spanning tree on many VLANs can cause
delays in BPDU transmission from that switch, which can cause all the non-root bridges in the
network to expire their message age timers, which may cause brief periods of network instability.
This problem is fixed in software release 5.3(1a)CSX. (CSCdk69087)
