Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S
Conditions: The symptom is observed on a Cisco 12000 series that runs a Cisco IOS interim release
for Release 12.0(31)S.
Workaround: There is no workaround.
• CSCeh30999
Symptoms: After you manually clear the tunnel between two PE routers or you reset one of the PE
routers, more than two tunnels are created between the PE routers.
Conditions: This symptom is observed when multiple dynamic or static sessions are configured
between two PE routers that are configured as L2TPv3 tunnel points.
Workaround: Reload both PE routers. If this not an option, there is no workaround.
• CSCeh31939
Symptoms: When a 1-port channelized OC-12/STM-4 (DS1/E1) ISE line card is configured for
MVPN on MLP interfaces and you reload the router, the PIM VRF neighbor may not be established
via a tunnel for some MLP interfaces.
Conditions: This symptom is observed on a Cisco 12000 series that runs the gsr-p-mz image of a
Cisco IOS interim release for Release 12.0(31)S.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the affected MLP interfaces.
• CSCeh33574
Symptoms: An Engine 4 plus or Engine 5 line card does not come up.
Conditions: This symptom is observed on a Cisco 12000 series that runs a Cisco IOS interim release
for Release 12.0(31)S when IPC timeout errors occur.
Workaround: There is no workaround.
• CSCeh34989
Symptoms: One of the following two symptoms may occur on a POS ISE egress line card:
–
The interface may become stuck during transmission. The line protocol will continuously flap
because the interface continues to receive keepalives but is not able to send any keepalives.
–
The line card generates the following harmless error message:
%EE48-4-GULF_TX_SRAM_ERROR: ASIC GULF: TX bad packet header detected.
Details=0x4000
Conditions: These symptoms are observed on a Cisco 12000 series when an invalid packet is
forwarded to an egress interface on an ISE line card.
Workaround: If the transmission on the interface is stuck, reload the line card by entering the
hw-module slot x reload command.
• CSCeh35411
Symptoms: A 4-port OC-12 POS Engine 2 line card may crash repeatedly when the Cisco 12000
series in which the line card is installed comes up after a software-forced crash has occurred on the
router.
Conditions: This symptom is observed on a Cisco 12000 series that runs the c12kprp-p-mz image of
a Cisco IOS interim release for Release 12.0(31)S, that is configured with two RPS, and that is
configured for SSO. The symptom is more likely to occur when the ipv6 unicast-routing command
is enabled.
Workaround: To diminish the chance that the symptom occurs, disable the ipv6 unicast-routing
command.
