Resolved Caveats

CSCtc57809
Switches running Cisco IOS Release 12.2(52)SE might reload after you enter the
no mac
address-table static
mac-address
vlan
vlan-id
interface
interface-id
global configuration
command if the interface is up and the MAC address was dynamically learned before it was changed
to static.
Use one of these workarounds:
–
Clear the dynamic MAC address table when configuring static MAC addresses as in this
example:
Switch(config)#
no mac address-table learning vlan
vlan_id
Switch(config)#
clear mac-address-table dynamic address
mac_address
Switch(config)#
mac address-table static
mac_address
vlan
vlan_id
interface
interface_id
Switch(config)#
mac address-table learning vlan
vlan_id
–
Downgrade to Cisco IOS Release 12.2(50)SE.
–
Upgrade to Cisco IOS Release 12.2(53)SE if available.

A switch that has at least one trunk port configured might fail when you configure more than 950
VLANS by using the
vlan
vlan-id global configuration command.
There is no workaround.

When a port that is configured for Switched Port Analyzer (SPAN) goes up and down, a memory
leak occurs in the ‘hpm main’ process.
There is no workaround.

A vulnerability in the Internet Group Management Protocol (IGMP) version 3 implementation of
Cisco IOS Software and Cisco IOS XE Software allows a remote unauthenticated attacker to cause
a reload of an affected device. Repeated attempts to exploit this vulnerability could result in a
sustained denial of service (DoS) condition. Cisco has released free software updates that address
this vulnerability.

CSCte72365
After a software upgrade from Cisco IOS Release 12.2(52)SE to Cisco IOS Release 12.2(53)SE,
EIGRP hello packets are flooded on access ports belonging to another subnet. The same result
occurs when you initiate ping requests to the broadcast address of other subnets. This results in
Not
on common subnet
errors on the other side of the link.
