Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S3
• CSCee38348
Symptoms: The SNMP counters and CLI for Frame Relay subinterfaces may be incorrect.
Conditions: This symptom is observed a Cisco 12000 series with ISE POS line cards.
Workaround: There is no workaround.
• CSCee38942
Symptoms: EoMPLS tunnels do not have labels assigned to them, preventing a virtual circuit from
coming up.
Conditions: This symptom is observed when multiple (for example, 1200) EoMPLS tunnels are
configured. Only on a few tunnels the symptom may not occur.
Workaround: There is no workaround.
• CSCee39853
Symptoms: A Cisco router that is running Cisco IOS Release 12.0(25)SX1 may experience CEF
disabling on standby PRE.
Conditions: This symptom is observed on a Cisco router that is running Cisco IOS
Release 12.0(25)SX1. The symptom may also occur in Release 12.0 S.
Workaround: Reset standby PRE.
• CSCee39854
Symptoms: A ping or Telnet connection to a connected CE router may fail from a Cisco 12000 series
router that functions as a PE router.
Conditions: This symptom is observed on Cisco 12012 that runs Cisco IOS Release 12.0(21)ST3 or
a later release when the router has a 3-port Gigabit Ethernet line card that is configured for dot1q
encapsulation on its subinterfaces.
This symptom occurs because of a misconfiguration on the subinterfaces: when you configure a
subinterface with new a VRF without removing the already configured VRF, the symptom occurs.
Workaround: Unconfigure and reconfigure the VRF configuration on the misconfigured
subinterfaces.
• CSCee42279
Symptoms: During an L2TPv3 test with a Cisco 12000 series 4-port OC-12 ATM line card, when
you bump traffic on more than two ports that process a high rate of traffic, traffic may stop. When
this situation occurs, the CPK24 FPGA on the line card generates ingress packet length errors and
sometimes SDRAM CRC errors.
Conditions: This symptom is observed on a 4-port OC-12 ATM line card that is configured for
L2TPv3 and that is installed in a Cisco 12000 series that runs the gsr-p-mz image of Cisco IOS
Release 12.0 S.
Workaround: Reload the line card.
• CSCee43562
Symptoms: The feature manager queue on the Route Processor may not drain for 20 minutes after a
reload in a scaled environment with 1400 IP and L3VPN connections (subinterfaces). The feature
manager pushes ACL and PBR configurations to the IP Services Engine (ISE) line cards for TCAM
processing. You can monitor the state of the feature manager queue with the show fm queue
command.
Conditions: This symptom is observed on a 12000 series that runs Cisco IOS Release 12.0(28)S and
may occur on any ISE line card that uses an associate message in the QoS manager.
