Symptoms: Memory allocations fail on the gateway though there is enough free memory. If this
failure happens in ISDN, the gateway crashes subsequently.
failure happens in ISDN, the gateway crashes subsequently.
Conditions: This symptom has been observed when the H323 aaa accounting command is enabled.
Workaround: There is no workaround.
Further Problem Description: Memory allocations for a block of 3k bytes fail with memory
fragmentation as the cause. When this failure occurs, there is approximately 20MB of free memory
on a gateway with 220MB of processor memory.

Symptoms: You cannot open a specific port on a Cisco IOS IP SLA responder.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.3(14)T1
when you attempt to open a specific port on the responder instead of using normal control protocol.
The symptom may also occur in Release 12.4 or Release 12.4T.
when you attempt to open a specific port on the responder instead of using normal control protocol.
The symptom may also occur in Release 12.4 or Release 12.4T.
Workaround: Use normal control protocol.

Symptoms: When the local method is used at the beginning of a PPP authentication method list and
when a user does not exist in the local database, failover to the next method in the method list does
not occur. This situation prevents users that are listed in the database of a RADIUS or TACACS+
server from being authenticated.
when a user does not exist in the local database, failover to the next method in the method list does
not occur. This situation prevents users that are listed in the database of a RADIUS or TACACS+
server from being authenticated.
Conditions: This symptom is observed on a Cisco router that is configured for AAA.
Workaround: Temporarily remove the local method from the beginning of the method list.

Symptoms: SNMP traps do not function, preventing an SNMP notification view from being properly
associated with a default group that was created via the snmp-server host command.
associated with a default group that was created via the snmp-server host command.
Conditions: This symptom is observed on a Cisco platform that runs Cisco IOS Release 12.4(2)T.
Workaround: Enter the show snmp view command to obtain the SNMP notification view and then
apply this view to the default group that was created via the snmp-server host command.

Symptoms: The transmit rate is higher than the configured committed information rate (CIR),
causing the network to drop frames.
causing the network to drop frames.
Conditions: This symptom is observed only when traffic is process-switched and when software
payload compression and header compression are configured.
payload compression and header compression are configured.
Workaround: Enable either CEF or fast-switching. If process-switching must be used, add a
compression adaptor and configure FRF9 data compression instead of packet-by-packet payload
compression. You can enable FRF9 data compression in the following ways:
compression adaptor and configure FRF9 data compression instead of packet-by-packet payload
compression. You can enable FRF9 data compression in the following ways:
–
On a point-to-point interface, enter the following command in interface configuration mode:

–
On a multipoint interface, enter the following command in interface configuration mode:
