Conditions: Occurs when the ATM packet size is greater than 1484 bytes.
Workaround: There is no workaround.
• CSCtw94068
Symptoms: The router displays traceback messages, after which interfaces stop passing traffic.

Workaround: There is no workaround.
• CSCtx37768
Symptoms: QoS classification does not match traffic against an egress policy map between MPLS
and IP access.
Conditions: This symptom is observed when a QoS policy is applied on an EVC bridge domain
interface.
Workaround: Use one of the following workarounds:
– Reload the router.
– Remove and re-apply an encapsulation configuration such a VLAN.
– Remove and re-attach the bridge domain under the EVC.
– Perform a shutdown/no shutdown on the BDI interface.
• CSCtx73691
Symptoms: The ASR 903 router forwards packets while in HSRP standby mode.
Conditions: Occurs when the ASR 903 is running HSRP and the HSRP session flaps.
Workaround: There is no workaround.
• CSCtx87145
Symptoms: The ASR 903 router does not support LDP label packets when transmitted in PTP
delay-request messages.
Conditions: Occurs when you configure the ASR 903 router as a PTP (1588 version) boundary
clock and the router sends an MPLS label packet within delay-request traffic.
Workaround: Align the grandmaster clock source to the same IGP domain and use a prefix-list for
local label filtering.
