Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: This has been always seen with an atm interface only when a rate-limit command is
enabled on the interface. The crash occurs when an interface that is configured with a rate-limit
command is deleted by entering the no interface command and then reenabled by entering the
interface command.
Workaround: Remove the rate-limit configuration from the interface before deleting the interface.
Further Problem Description: Happens under very specific circumstances and the crash is seen
randomly.

Symptoms: If a user fails to successfully establish a SSH connection on the first attempt, subsequent
attempts may also fail.
Conditions: Occurs when a Cisco router is configured to authenticate SSH connections using
TACACS+. The rem_addr field in the TACACS+ header may be empty if the user does not
successfully authenticate on the first attempt. This may cause authentication or authorization
failures if rem_addr information is required by the TACACS+ server.
Workaround: Configure ipssh authentication-retries 0.

Symptoms: The output counters for a Multilink Frame Relay (MFR) bundle interface may not be
updated correctly.
Conditions: Occurs after the same interface is deleted and recreated.
Workaround: There is no workaround.

Symptoms: The Unavailable Seconds (UAS) that are displayed in the output of the show controllers
serial slot/port command are incorrect. The display of the UAS starts only after 20 contiguous
severely errored seconds (SES) instead of after 10 contiguous SES.
Conditions: This symptom is observed on a Cisco 7200 series that is configured with a PA-T3+ port
adapter.
Workaround: There is no workaround.

Symptoms: A memory leak may occur in the "BGP Router" process.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0(26)S6,
that is configured for BGP, and that has the /jointfilesconvert/422273/bgp regexp deterministic command enabled.
Workaround: Disable the /jointfilesconvert/422273/bgp regexp deterministic command.

Symptoms: When you perform an OIR of an ATM line card, a CPUHOG condition may occur in the
"BGP Event" process.
Conditions: This symptom is observed when the ATM line card is configured with about 15,000 /32
routes.
Workaround: There is no workaround.
Further Problem Description: The ATM line card connects to about 15,000 different gateways, each
of which is covered by its own /32 route. In addition, there is a less specific route that covers
everything. The symptom occurs when BGP attempts to remove a large number of these tracked
entries without suspending any.
