–
1-port Gigabit Ethernet line card (GE-GBIC-SC-B)
Workaround: There is no workaround.
• CSCin79691
Symptoms: QoS information disappears from a FlexWAN module or VIP that is configured with a
distributed MFR interface.
Conditions: This symptom is observed after the FlexWAN module or VIP resets or after the interface
flaps.
Workaround: Remove the service policy from the interface and reapply it to the interface.
• 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.
• CSCin96692
Symptoms: On a Cisco 7500 series that is configured for dMLP, the txacc values of member
interfaces may be wrongly credited to other member interfaces, causing RSP-3-RESTART
messages, and finally causing traffic to stop.
Conditions: This symptom is observed when the member links flap continuously for some time
while traffic is being processed.
Workaround: There is no workaround.
• CSCsa70494
Symptoms: When the remote router is reloaded, the local router reports an error message such as the
following one:
%SPA_CHOC_DSX-3-HDLC_CTRL_ERR: SPA 5/2: 6 TX Chnl Queue Overflow events on HDLC
Controller were encountered.
This situation causes some packets to become lost.
Conditions: This symptom is observed on a Cisco router that is configured with a channelized T3 to
DS0 SPA when the following conditions occur:
–
The SPA is configured with many multilink bundles.
–
A heavy traffic load is being processed.
–
Links go down at the remote end.
Workaround: Shut down the links on the channelized T3 to DS0 SPA before the router at the remote
site is reloaded. If this is not an option, there is no workaround.
• CSCsa80620
Symptoms: Member links of a multilink bundle remain down, traffic does not flow, and an error
message similar to the following is generated on the console of the RP and line card:
%C7600_SIP200_SPITX-3-EFC_QUEUE_STUCK: Se4/2/0/3:0
Conditions: This symptom is observed on a Cisco router and Cisco switch that are configured with
a 2- or 4-port channelized T3 to DS0 SPA when a member link of a multilink bundle is directly added
to another multilink bundle without first deleting the member link from the first bundle.
Workaround: First delete the member link from one multilink bundle before you add the member
link to another multilink bundle.
