OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S4
• CSCei50162
Symptoms: The physical layer interface module (PLIM) of a 6-port channelized T3 that is
configured for MLP may not be updated with MLP link information.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S4 after you have reloaded the router.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the affected MLP interfaces.
• CSCei51504
Symptoms: When you run an SNMP get or walk on the ifOperStatus object on a 1-port CHOC-12
OC-3 ISE line card, the status for the STS-1 path interface shows down although the channel is up.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S3.
Workaround: There is no workaround.
• CSCei66187
Symptoms: Multilink PPP interfaces flap more than once.
Conditions: This symptom is observed following an RPR+ switchover for a 1-port ISE OC-12
channelized to DS1/E1 line card that is configured with 168 multilink VRF interfaces, all of which
are configured for QoS.
Workaround: There is no workaround.
• CSCin72437
Symptoms: A port adapter in a router or FlexWan module in a switch may crash when an SSO
switchover occurs on a Route Processor or Supervisor Engine.
Conditions: This symptom is observed when the port adapter or FlexWan module is configured with
a QoS policy.
Workaround: There is no workaround.
• CSCin91381
Symptoms: A VIP that has a dMLFR configuration may crash when you enter the microcode reload
global configuration command.
Conditions: This symptom is observed on a Cisco 7500 series when traffic flows through the VIP.
Workaround: There is no workaround.
• CSCsa59109
Symptoms: At random, subinterfaces loose the ability to ping a directly-connected peer.
Conditions: This symptom is observed on a Cisco 12000 series that is configured with two 3-port
Gigabit Ethernet line cards.
Note that although regular and extended pings do not work, pings that use the record option do work.
Workaround: Reload microcode onto the affected line cards.
• CSCsa59829
Symptoms: With traffic passing over a network only occasionally, a 4-port OC12 ATM ISE line card
generates a “%PM622-3-CPK24_INTR: Egr SAR timeout” error message and resets.
Conditions: This symptom is observed on a Cisco 12000 series.
Workaround: Reload the line card.
