Cisco IOS XE 3S Release Notes for the Cisco ASR 903 Router
OL-26630-08
Caveats in Cisco IOS XE 3.9S Releases
• CSCug05239
Symptom: Traffic drops on the router.
Conditions: This issue occurs when configuring multichassis Link Aggregation Control Protocol
(MLACP) switchover with Ethernet over Multiprotocol Label Switching (EOMPLS).
Workaround: Configure port channel with EOMPLS.
• CSCug10116
Symptom: Traffic and ping do not flow through ATM interfaces on multiple controllers.
Conditions: Series of shutdown and no shutdown commands on the controller or interface lead to
the failure.
Workaround: There is no workaround. To recover from failure, perform an IM OIR.
• CSCug18185
Symptom: When the interfaces comes up after bootup, traffic received on the Cisco ASR 903 Router
serial interfaces are not switched to the BDI connected to Ixia.
Conditions: This issue occurs when ARP resolution of the Ixia connected interface IP address fails.
Workaround: Ping the Ixia port connected to the Cisco ASR 903 Router from another router
connected to the Cisco ASR 903 Router using Gigabit Ethernet interface.
• CSCug18630
Symptom: When you perform an OIR on the standby and active RSPs, CMAND crashes.
Conditions: This issue is observed after performing multiple standby OIRs and bringing the standby
machine up.
Workaround: There is no workaround.
• CSCug21145
Symptom: When system crashes, sometimes core files are generated with CRC errors.
Conditions: This issue occurs when the system crashes under stress conditions.
Workaround: There is no workaround.
• CSCug27073
Symptom: Multicast replication is improper when 255 outgoing interfaces (OIF’s) are configured.
Conditions: This issue occurs when:
– Perfuming IM OIR (soft/hard)
– Clearing MRoutes (sometimes)
– Enabling/disabling IGMP Snooping
Workaround: There is no workaround.
• CSCug31414
Symptom: Multicast traffic drops on changing interface configuration from TEFP to VPLS over
port channel (PoCH).
Conditions: This issue occurs when converting a layer 2 interface to layer 3; and then configuring
IP PIM and IP address in quick succession.
Workaround: Use shutdown and no shutdown command on the interface.
More Info: The problem occurs only when the adjacency create notification is received earlier than
the convert to layer 3 notification.
