Caveats for Cisco IOS Release 12.0
78-6455-12
Resolved Caveats—Cisco IOS Release 12.0(9)
Workaround: Use the script startup line configuration command and the script reset line
configuration command.
Basic System Services
• CSCdm20829
If you enter the show interfaces [type number][first][last][accounting] EXEC command on a
Cisco router that is running Cisco IOS Release 12.0(3)T, the accounting records are updated only
when the first system interface is sampled, and all interfaces share the accounting record of the first
interface. There is no workaround.
• CSCdm67579
A Cisco router might stop responding to Simple Network Management Protocol (SNMP) queries.
This situation occurs when the number of SNMP request packets to be processed at the same time
is high. There is no workaround.
• CSCdm88410
A Cisco router might reload when you enter the write memory EXEC command at the router
prompt. This happens during nonvolatile generation (nvgen) of the line global configuration
command. There is no workaround.
• CSCdp08710
A Cisco 7200 series router with a compression service adapter (CSA) that is configured with Frame
Relay Traffic Shaping (FRTS), and using either Cisco Express Forwarding (CEF) or fast switching
will not compress data when the amount of data on the interface is greater than the shaping value
(for example, CSA will stop compression when traffic shaping becomes active).
Workaround: Use process switching.
• CSCdp16189
Configuring trigger authentication by entering the ip trigger-authentication interface
configuration command might cause a memory leak. There is no workaround.
• CSCdp60260
A Cisco router might reload when hardware compression is configured in conjunction with Generic
Traffic Shaping and Fancy Queueing on a compression service adapter (CSA) at the main interface.
This situation only occurs when all 3 features are configured.
Workaround: Use software compression.
DECnet
• CSCdp05189
If you configure a Cisco router using the decnet routing-timer seconds interface configuration
command, the router might create a DECnet in-routing filter access list number after you reload the
router. The access list number will be the same as the time in seconds specified in the
decnet routing-timer seconds interface configuration command, and might be invalid. There is no
workaround.
• CSCdp21639
If a Cisco router is running a release earlier than Cisco IOS Release 11.3 and is using the DECnet
Phase IV routing protocol, the DECnet network might experience loops or the incorrect selection
of routes for periods of time up the value entered with the decnet routing-timer interface
