Caveats in Cisco IOS XE 3.7S Releases
• CSCuc43719
Symptoms: The router crashes.
Conditions: Occurs when you apply a Network Based Application Recognition (NBAR)
configuration to the router. There is no specific trigger.
Workaround: Remove the NBAR configuration, it is not supported.
• CSCuc55382
Symptoms: The show inventory command displays incorrect serial number for SFPs and XFPs.
Conditions: Occurs after you issue repeated stateful switchovers (SSOs).
Workaround: There is no workaround.
• CSCuc59386
Symptoms: Continuous IOMD crashes occur on OC-3 IM. Interfaces on OC-3 IM are not
configurable and the router displays the the following error message:
"stand-by does not support this command"
Conditions: Occurs with OC-3 IM in a redundant configuration when an IOMD crash occurs on the
active RSP and the standby IOMD session handle is not cleared.
Workaround: Reload the standby RSP.
• CSCuc62784
Symptoms: The router displays traceback error messages at niles_if_count_initialize
Conditions: Occurs following a reload or stateful switchover (SSO).
Workaround: There is no workaround. However, the issue does not have any functionality impact.
• 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.
• CSCuc66393
Symptom: The router loses OC-3 interface configurations after an ISSU upgrade.
Conditions: Occurs on OC-3 serial and POS interfaces after an ISSU software upgrade.
