Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: Following error message are seen when the frame-relay fragment <fragment size>
command is configured under map-class attached to PVC:
% Fragment size 110 not supported. Supported fragment size are 128, 256 and 512. Rounding
current fragment config to 128.
Conditions: This seen in distributed platforms (Cisco 7600) when fragment size configured is not
128, 256, or 512.
Workaround: Configure the fragment size as 128, 256 or 512

Conditions: Occurs when configuring and unconfiguring 4 "cem-groups" per controller.
Workaround: There is no workaround.
CSCsx95338
Symptoms: Crash occurs when BGP configuration is removed.
Conditions: BGP is checkpointing routes to the redundant RRP when the configuration change
occurs. More likely to occur in a scaled setup.

CSCsy07555
Cisco IOS devices that are configured for Internet Key Exchange (IKE) protocol and certificate
based authentication are vulnerable to a resource exhaustion attack. Successful exploitation of this
vulnerability may result in the allocation of all available Phase 1 security associations (SA) and
prevent the establishment of new IPsec sessions.
Cisco has released free software updates that address this vulnerability.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090923-ipsec.shtml
CSCsy07953
Symptoms: Any attempt to copy a file from a router to an FTP server will fail. The FTP error is "No
such file or directory".
Conditions: This is only a problem with FTP and only when transferring to an FTP server. Transfers
from an FTP server work as expected.
Workaround: Use a different file transfer protocol, such as TFTP.
