Resolved Caveats—Cisco IOS Release 12.0(28)S3
• CSCeh20201
Symptoms: Traffic entering a 1-port channelized OC-12/STM-4 (DS1/E1) ISE line card is dropped.
Conditions: This symptom is observed on a Cisco 12000 series when an MLP interface is moved
from the 1-port channelized OC-12/STM-4 (DS1/E1) ISE line card to another line card.
Workaround: There is no workaround.
• CSCeh20219
Symptoms: The policer does not function for nxDs0 interfaces.
Conditions: This symptom is observed on a Cisco 12000 series that is configured with a 1-port
channelized OC-12c/STM-4 (DS1/E1) ISE line card.
Workaround: There is no workaround.
• CSCeh27734
Symptoms: For recursive routes with implicit null as the local label, the FIB may point to the rewrite
of the parent prefix. However, this situation may not affect any functionality.
Conditions: This symptom is observed on a router that is configured for MPLS forwarding.
Workaround: Change the affected prefix to be non-recursive.
• 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.
