Chapter
Caveats in Cisco IOS XE 3.7S Releases
• CSCue77612
Symptom: MAC address synchronization on 1 Gigabit Ethernet port on standby RSP causes traffic
to be forwarded to incorrect port after a switchover.
Conditions: This issue occurs after a switchover.
Workaround: Clear MAC address after a switchover is performed.
• CSCue86696
Symptom: Interface flaps after longevity run is performed.
Conditions: This issue occurs after prolonged tests are performed with SPF interface modules.
Workaround: There is no workaround.
• CSCue87542
Symptom: Deleting bridge domain interfaces (BDIs) with routing traffic causes a flood to CPU
resulting in control plane traffic loss.
Conditions: This issue occurs after a ping failure and the Bidirectional Forwarding Detection
(BFD) protocol or OSFP protocol flaps on deleting the BDI while IPv4 traffic is flowing.
Workaround: Delete the Trunk EFP interface and then the BDI.
• CSCue89503
Symptom: The power supply status displays critical after removing and inserting the power supply
on the Cisco ASR903 router.
Conditions: This issue occurs after multiple OIR of the power supply is performed.
Workaround: There is no workaround. This issue is cosmetic.
• CSCuf05039
Symptom: I2C-WRITE and MDIO_READ error messages are displayed on the Cisco ASR903
router.
Conditions: This issue occurs after an interface module hard or soft OIR is performed.
Workaround: There is no workaround.
• CSCuf61365
Symptom: Virtual circuit counters do not increment after interface module Online Insertion and
Removal (OIR) followed by a SSO is performed.
Conditions: This issue occurs after an OIR followed by a SSO is performed.
Workaround: Perform a SSO without a interface module OIR.
• CSCuf65040
Symptom: 1 Gigabit Ethernet or 10 Gigabit Ethernet interface module enters out of service state.
Conditions: This issue occurs when a hard Online Insertion and Removal (OIR) is performed on the
interface module.
Workaround: Perform another hard OIR or a Stateful Switchover (SSO) followed by a soft OIR.
