OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S2
Conditions: This symptom is observed when the import map word command is configured as part
of the VRF configuration. Note that eBGP routes are not filtered out.
Workaround: There is no workaround.
• CSCed85254
Symptoms: MPLS forwarding may stop.
Conditions: This symptom is observed under the following conditions:
– When you change a COS map or prefix map.
– When you change an IP access list.
Workaround: There is no workaround.
• CSCed85324
Symptoms: Stale MPLS COS per-route entries may be left behind.
Conditions: This symptom is observed after the route disappears from the routing table in cell mode
multi-VC network.
Workaround: There is no workaround.
• CSCed95499
Symptoms: A Cisco router may crash if a PA driver attempts to convert an uncached iomem address
to a cached iomem address.
Conditions: This symptom is observed on a Cisco 7200 series that is configured with an NPE-G1.
Workaround: There is no workaround.
• CSCee07351
Symptoms: An LC-ATM-enabled subinterface on a PE router remains in the “not ready” state when
you view the LDP session to the LSC in the output of the show mpls ldp discovery command.
Entering the shutdown interface configuration command followed by the no shutdown interface
configuration command on either the LC-ATM subinterface on the PE router or on the Xtag interface
on the connected LSC does not clear the problem.
Conditions: This symptom is observed when the interface stays in the “interface not LDP ready”
state and when there exists a stray LVC on the switch interface. The PE router reaches this state after
multiple LDP flaps.
Workaround: Clear the symptoms by entering the clear ip route prefix command, in which the prefix
argument is the local loopback address for the LC-ATM subinterface. Doing so causes all tailend
LVCs on all LC-ATM subinterfaces to be torn down and re-established, and causes a brief customer
outage. Only use this workaround if no alternate path (such as a redundant LC-ATM subinterface)
exists for MPLS traffic towards the device. After applying the workaround, check the output of the
show mpls atm summary command to confirm that the expected number of LVCs has been
re-established. If bindings are not successfully re-established, re-enter the clear ip route prefix
command, or reload the router.
When you reload the router, the stray LVC is removed and the LDP session on the LC-ATM
subinterface of the PE router is brought back to a normal state.
• CSCee16205
Symptoms: The committed information rate (CIR), normal burst, and maximum burst of the police
(percent) command in a policy map are set incorrectly.
Conditions: This symptom is observed when the policy map is attached to an MLP interface that is
configured for LFI and that is in the “DOWN” state.
