OL-26630-08
Conditions: Occurs after you issue an OIR on the T1/E1 interface module from the active RSP. The
issue occurs in a redundant system.
Workaround: There is no workaround.
CSCub74338
Symptoms: The router crashes.
Conditions: Occurs when you attach an ingress QoS policy-map to an EVC with a rewrite push
configuration.
Workaround: There is no workaround.
CSCub77285
Symptom: Some T1/E1 interfaces do not come up.
Conditions: Occurs with T1/E1 configurations at a high scale; the interfaces display a false alarm.
Workaround: Reset individual T1/E1 interfaces; after a reset, the interfaces become active.
CSCub89029
Symptoms: When the router boots, copper Gigabit Ethernet ports display an up/up status but do not
pass traffic.
Conditions: Occurs when the port has a negotiated speed other than 1 Gigabit, such as 100 Mbps.
Workaround: Issue a shutdown/no shutdown on affected ports.
CSCuc36241
Symptoms: The router is unable to select a given PTP clock as a network clock source.
Conditions: Occurs when you configure PTP as an input network clock source while the slave clock
is still in a holdover state. In the holdover state, the slave clock has not yet attempted to establish a
frequency lock with a master clock.
Workaround: Wait for the PTP slave clock to lock to the master clock before configuring PTP as a
network clock input source.
CSCts95896
Symptoms: The router stops passing traffic on EVC interfaces.
Conditions: Occurs when you issue the default interface command and immediately restore the
configuration. The issue occurs with configurations containing either a large number of EFPs or
features that impact EFP programming at a lesser scale, such as QoS.
Workaround: Wait for the router to clear the old EFP configuration before adding a new
configuration.
CSCtw72855
Symptoms: The router does not pass traffic towards the access side on VCs configured with QoS
shaping output policy.
Conditions: Occurs when you configure a QoS shaping output policy.
Workaround: There is no workaround.
