OL-1617-14 Rev. Q0

Caveats

Resolved Caveats—Cisco IOS Release 12.0(32)S

Workaround: There is no workaround. If all line cards are affected, enter the clear cef linecard

command to recover from the symptom. If a specific line card is affected, enter the clear cef

linecard slot-number command to recover from the symptom. Enter these command from a console

that is attached to the RP or RRP.

TCP/IP Host-Mode Services

• CSCsb51019

Symptoms: A TCP session does not time out but is stuck in the FINWAIT1 state and the following

error message is generated:

%TCP-6-BADAUTH: No MD5 digest from x.x.x.x to y.y.y.y(179) (RST)

Conditions: This symptom is observed on a Cisco 12000 series that is configured for BGP and that

is connected to a third-party vendor router after the BGP authentication password is changed on the

Cisco 12000 series.

Workaround: There is no workaround.

• CSCsc39357

Symptoms: A Cisco router may drop a TCP connection to a remote router.

Conditions: This symptom is observed when an active TCP connection is established and when data

is sent by the Cisco router to the remote router at a much faster rate than what the remote router can

handle, causing the remote router to advertise a zero window. Subsequently, when the remote router

reads the data, the window is re-opened and the new window is advertised. When this situation

occurs, and when the Cisco router has saved data to TCP in order to be send to the remote router,

the Cisco router may drop the TCP connection.

Workaround: Increase the window size on both ends to alleviate the symptom to a certain extent. On

the Cisco router, enter the ip tcp window-size bytes command. When you use a Telnet connection,

reduce the screen-length argument in the terminal length screen-length command to 20 or 30 lines.

Further Problem Description: BGP in Cisco IOS Release 12.0S and Release 12.4 is not affected

because the retransmit timeout is disabled for BGP in these releases.

Wide-Area Networking

• CSCef54653

Symptoms: Some members of a multilink bundle remain inactive, while others are active.

Conditions: This symptom is observed when the interfaces are configured with the ppp chap

hostname or ppp multilink endpoint command. Very high speed interfaces may come up and join

the multilink bundle faster than the configuration can be processed, which causes them to use the

host name of the router (instead of the configured user name or endpoint value) as the Endpoint

Discriminator during Link Control Protocol (LCP) negotiations. This situation causes a mismatch

between these links and those that come up after the configuration command is processed.

Workaround: Enter the shutdown interface configuration command followed by no shutdown

interface configuration command on the active links to enable the links to renegotiate LCP with the

correct Endpoint Discriminator value.

• CSCef71011

Symptoms: Pings fail when translational bridging and ATM DXI encapsulation are configured.

Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0S,

Release 12.2S, or a release that is based on Release 12.2S.
