OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S1
• CSCee35659
Symptoms: A priority class cannot be configured if the remaining bandwidth is used on the existing
classes. Such a service policy is rejected.
Conditions: This symptom is observed on Cisco 12000 series-ISE based line cards.
Workaround: Use police actions in the priority class in conjunction with bandwidth percentages on
the existing classes.
• CSCee36050
Symptoms: A VIP crashes with the following error message:
VIP-3-SYSTEM_EXCEPTION: VIP System Exception occurred sig=10, code=0x10
Conditions: This symptom is observed on a Cisco 7500 series when you re-use a channel group (or
subinterface) that was previously configured with a Frame Relay DLCI “set” service policy.
Workaround: Remove the “set” service-policy before you remove the channel group (or
subinterface).
• CSCee38324
Symptoms: A VIP may crash.
Conditions: This symptom is observed on a Cisco 7500 series when QoS is configured on the
interface of the VIP and traffic is flowing.
Workaround: There is no workaround.
• 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.
