Release Notes for Catalyst 4900M, Catalyst 4948E and Catalyst 4948E-F Series Switches, Cisco IOS Release 15.2(4)Ex
Caveats
'Failed to configure service policy on register tunnel' and 'STANDBY:Failed to
configure service policy on register tunnel'.
Workaround: None. The ip pim register-rate-limit command does not function. CSCub32679
•
For packets with the same ingress and egress Layer 3 interface, ingress QoS marking policy does
not work.
not work.
Workaround: Turn off ICMP redirect through the ip redirect command. CSCua71929
•
While configuring an IPv6 access-list, if you specify hardware statistics as the first statement in
v6 access-list mode (i.e. before issuing any other v6 ACE statement), it will not take effect.
Similarly, your hardware statistics configuration will be missing from the output of the show
running command.

Similarly, your hardware statistics configuration will be missing from the output of the show
running command.
You will not experience this behavior with IPv4 access lists.
Workaround: During IPv6 access-list configuration, configure at least one IPv6 ACE before the
"hardware statistics" statement. CSCuc53234

When an IPv6 FHS policy is applied on a VLAN and an EtherChannel port is part of that VLAN,
packets received by EtherChannel (from neighbors) are not bridged across the local switch.
packets received by EtherChannel (from neighbors) are not bridged across the local switch.
Workaround: Apply FHS policies on a non EtherChannel port rather than a VLAN. CSCua53148
•
Memory allocation failures can occur if more than 16K IPv6 multicast snooping entries are present.
Workaround: None. CSCuc77376
•
For any configuration where the source-interface keyword is used, if you provide an SVI that is
associated with a secondary private VLAN, configuration involving the secondary VLAN may be
lost when the switch is reloaded. In such scenarios, always use the primary private VLAN.

•
When a logging discriminator is configured and applied to a device, memory leak is seen under
heavy syslog or debug output. The rate of the leak is dependent on the quantity of logs produced. In
extreme cases, the device may crash. As a workaround, disable the logging discriminator on the
device (CSCur45606, CSCur28336).
