Resolved Caveats—Cisco IOS Release 12.0(6)
• CSCdm28939
When you configure DECnet on a router, it is possible to specify an Address Translation Gateway
(ATG) network number in the range 0 to 3. If the ATG-network-number is specified incorrectly
when you configure an interface, the router might reload. If ATG-network-number is not required,
it does not need to be specified and the problem does not occur. If ATG-network-number is
required, use the following workaround.
Workaround: Ensure that the ATG-network-number you specify when enabling an interface
matches the one specified when DECnet routing is enabled globally (for example,
decnet 1 routing 2.3 interface ethernet 0/0 decnet 1 cost 5).
EXEC and Configuration Parser
• CSCdm58734
The padding command on a line configuration is lost after the first successful connection. The
command is reported when you issue the sh configuration command, but not when you issue the
sh running -config command.
Workaround: Reconfigure the padding command.
IBM Connectivity
• CSCdm11922
If you use a data-link switching (DLSw) direct-encapsulation serial-link WAN with Ethernet LAN
on one side and Token Ring LAN on the other, connections can only be established from the Token
Ring side.
Workaround: Raise the maximum transmission unit (MTU) of the serial WAN to approximately
1800 bytes.
• CSCdm30793
A Cisco 7206 router that is configured for DLSw priority peers might reload with a bus error when
running Cisco IOS Release 11.3(9)T. There is no workaround.
• CSCdm37638
Some Cisco 4500 series routers and Cisco 4700 series routers with a 2-Port Token Ring Network
Processor Module (NP-2R) might hang once a week (no matter the revision level of the
motherboard), and display the following message:
%SYS-2-INPUTQ: INPUTQ set, but no IDB
Workaround: Issue the lnm disable command to temporarily correct the problem.
• CSCdm38759
If a Router Switch Module (RSM) is configured with IBM spanning tree, and IP routing is disabled,
it does not respond to a single-route or all-route ARP frame destined to its MAC address.
Workaround: Disable IBM spanning tree on the RSM.
• CSCdm39124
Console message flooding might occur when an XID3 loop occurs with an APPN in the router. The
following messages are repeated for each iteration of the loop:
%APPN-3-logcsCS_XXXXIP11_LOGMSG_01: CS - Sending Alert to MS, sense_code = 83E0001,
proc_name = XXXXIP32, port_name = HMAC04, ls_name = @LS00289
%APPN-3-logcsCS_XXXXIP11_LOGMSG_03: CS - Associated outbound XID data in alert (length
