Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S
Workaround: Performing a shut command followed by a no shut command on the PVC will
reactivate it.
Alternate Workaround: Disable OAM management.
• CSCed00334
Symptoms: A router crashes on configuring an ATM ESI address.
Conditions: This symptom is observed when a deleted subinterface is reused.
Workaround: There is no workaround.
• CSCed01613
Symptoms: The data path may be broken.
Conditions: This symptom is observed on an interface of a CE router when L2TPv3 sequencing is
configured for AAL5 over L2TPv3 (pseudo-wire type).
Workaround: Disable L2TPv3 sequencing.
• CSCed02802
Symptoms: A 1-port 10-Gigabit Ethernet line card may generate pause frames under an inbound
heavy load if there is a bottle neck in the router, for example an egress line card. The pause frames
may cause FCS errors at the remote end device.
Conditions: This symptom is observed on a Cisco 12000 series router that is running Cisco IOS
Release 12.0(25)S2.
Workaround: There is no workaround.
• CSCed02859
Symptoms: During installation of a router on an OC-48 DPT/RPR ring, the ring became unstable,
and 5 Cisco 12000 series routers reloaded, one reloading twice.
Conditions: This symptom is observed on a mix of Cisco 12016 routers and Cisco 12416 routers that
are running Cisco IOS Release 12.0(23)S3 3DES software.
Workaround: There is no workaround.
• CSCed03096
Symptoms: Shutting down the loopback 0 causes the 3xGigabit Ethernet (engine 2) line card to fail
when it is configured with EoMPLS and VPN, and hardware multicast is enabled. This also happens
on POS line cards and if a line card reload is done when multicast and VPN are both enabled.
Conditions: This symptom is observed on a Cisco 12000 series router that is running Cisco IOS
Release 12.0(27)S.
Workaround: There is no workaround.
• CSCed05344
Symptoms: The Gigabit Ethernet port on a 10-port Gigabit Ethernet base card may be in the up/up
state even though there are no cables plugged in.
Conditions: This symptom is observed when the 10-port Gigabit Ethernet card has one EPA in the
top slot and two ports on the EPA configured and enabled. Each time the router is booted, the Gigabit
Ethernet port on the 10-port Gigabit Ethernet base card is in the up/up state.
Workaround: There is no workaround.
• CSCed06014
Symptoms: On a Cisco router, IPv6 traffic is counted under IPv4 counter on the Engine 4 POS line
cards on the egress side when using the show interface number [accounting] command.
