Caveats in Cisco IOS XE 3.7S Releases
• CSCud83698
Symptom: Links on the Gigabit Ethernet interface do not become active.
Conditions: Occurs on the Gigabit Ethernet interface when the local interface is configured for
autonegotiation and the remote interface is configured for a speed of 10 Mbps or 100 Mbps.
Workaround: Toggle the auto-negotiation configuration on the Gigabit Ethernet interface.
• CSCud89451
Symptom: The router crashes with an error message showing nmpls_label_populate_flow_data.
Conditions: This issue occurs when the core interface is reset while the Cisco ASR 903 acts as a
PE router running a configuration with Layer2 VPN and Layer3 VPN.
Workaround: There is no workaround.
• CSCud90457
Symptoms: The serial interface of Circuit Emulation interfaces connected to the CEM interfaces on
PE remain down on router reload with scaled configuration.
Conditions: This issue is observed when you have Circuit Emulation Services over Packet (CESoP)
and Structure-agnostic TDM over Packet (SAToP) scaled circuits and perform a router reload.
Workaround: Perform IM OIR to resolve the issue.
• CSCud90735
Symptom: The controller comes up without having a license.
Conditions: This issue occurs 16 port t1/e1 license are installed on PE1_W2
Workaround: There is no workaround.
• CSCud90890
Symptom: Routing over Trunk EFP over port-channel does not work on member ports associated
with ASIC #1.
Conditions: This issue occurs if a Trunk EFP on port-channel has members on ASIC #1.
Workaround: There is no workaround.
• CSCud95359
Symptom: The show policy map command displays an incorrect number of total dropped packets
(total drops).
Conditions: This issue occurs when the show policy-map command displays dropped packets on an
interface.
Workaround: There is no workaround.
• CSCud96604
Symptoms: On system reset or reload, all traffic on certain Ethernet Flow Point (EFP)s do not
egress.
Conditions: This issue occurs when traffic completely stops on certain EFPs.
Workaround: Delete and reconfigure EFPs.
• CSCud96962, CSCud97289
Symptom: After performing a shutdown followed by a noshutdown the member-link Connectivity
Fault Management (CFM) crash is observed
