Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S5
Conditions: This symptom is observed when an interface that is configured for some form of fancy
queueing (that is, anything besides FIFO queueing) actively forwards traffic.
Workaround: Disable fancy queueing on the Ethernet interface.
CSCek08638
Symptoms: Data traffic that is received by a provider edge (PE) router on an Ethernet port may not
be forwarded over an L2TPv3 tunnel.
Conditions: This symptom is observed on a Cisco 12000 series when the line card that faces the
customer edge (CE) router is one of the following line cards:
8-port Fast Ethernet, 100BASE-FX line card (8FE-FX-SC-B)
8-port Fast Ethernet, 100BASE-TX line card (8FE-TX-RJ45-B)
1-port Gigabit Ethernet line card (GE-GBIC-SC-B)
Workaround: There is no workaround.
CSCek24821
Symptoms: The memory of a SIP-400 depletes entirely, and the following error message is
generated:
EE48-3-ALPHA_MCAST: Can’t assign new hw_mdb - (S,G)=(<IP>), mi=431, side=TX
Conditions: This symptom is observed on a Cisco 12000 series that functions as a PE router when
the following conditions are present:
The router receives traffic with invalid sources, that is the traffic is sent from sources that are
not in the global routing table, causing RPF to fail.
(S,G) information is still created for the invalid sources, and when the (S,G) information times
out, the memory of the SIP-400 is not released.
Regular traffic comes from a valid source and is directed to the same group address.
The non-RPF source has a hash collision with the valid traffic stream.
Workaround: There is no workaround.
CSCek25127
Symptoms: There is no IPv4 BGP MPLS functionality between BGP peers.
Conditions: This symptom is observed on a Cisco 12000 series that is connected to a BGP peer over
a link bundle interface.
Workaround: There is no workaround.
CSCek27756
Symptoms: All interfaces of a 24-port channelized E1/T1 line card flap.
Conditions: This symptom is observed on a Cisco 10000 series when extensive channel
reprovisioning is configured on the line card.
Workaround: Perform a microcode reload for the line card and then reset the line card.
CSCek28323
Symptoms: An interface of an Engine 3 ingress line card that functions in feature mode may become
stuck, and all traffic may be dropped.
Conditions: This symptom is observed on a Cisco 12000 series that is configured with an Engine 3
ingress line card that has the hw-module slot slot-number np mode feature command enabled and
that is configured with an egress line card that has a link bundle interface.
