Caveats in Cisco IOS XE 3.7S Releases
Conditions: Occurs when the router is configured as a hybrid clock (ordinary/boundary) and there
are intermediate hops between the router and the PTP master clock. To date the problem occurs only
when the intermediate hops are through an ASR 9000 router.
Workaround: There is no workaround.
• CSCuc44701
Symptom: The router displays an error message similar to the following: Oct 1 12:07:21.806 IST:
%CMRP-3-CHASSIS_MONITOR_READY_TIME_EXCEEDED: R1/0: cmand: Reloading F1
because it has failed to become ready for packet processing
Conditions: Occurs when you reload the router while running a configuration that contains

Workaround: There is no workaround.
• CSCuc64654
Symptom: The router is unable to ping the remote customer edge (CE) router.
Conditions: Occurs when the router is acting as a provider edge (PE) device and is connected to the
remote PE using dual loopback interfaces for peering with iBGP sessions.
Workaround: Use a single loopback interface. Use the same loopback interface for IPv4 and
VPNv4 address families.
• CSCuc68699
Symptom: The router displays a segmentation fault error message at cgmu_nq_ccm_convert and
crashes.
Conditions: Occurs when you:

•
Symptom: The router drops traffic during stateful switchover (SSO).
Conditions: Occurs when the router is running HSRP or VRRP; the issue only occurs when the
destination MAC address is a virtual MAC (vMAC) address.
Workaround: Change the traffic priority and detour traffic prior to the SSO.
CSCuc88066
•
Symptom: The router does not classify egress traffic and the show policy-map interface command
counters do not increment.
Conditions: Occurs when you configure an output QoS policy to an EFP interface.
Workaround: Remove and reconfigure the service policy on the EFP interface.
CSCuc92350
•
Symptom: A connection between two copper SFPs does not become active.
Conditions: Occurs when two SFP interfaces are connected with one side set to 100 Mbps and the
other side set to negotiation auto.
Workaround: Set the speed to 10Mbps at both sides, then configure negotiation auto on one side
of the connection.
