Resolved Caveats—Cisco IOS Release 12.0(28)S4
• CSCeh78918
Symptoms: When a line card has reloaded because you reloaded the router, the line card crashed, or
you entered a command to reload the line card, the following message may appear on the console:
%MDS-2-RP: MDFS is disabled on some line card(s). Use "show ip mds stats linecard" to
view status and "clear ip mds linecard" to reset.
This message may be generated because MDFS is erroneously disabled on the reloaded line card.
Erroneous disabling of MDFS may unnecessarily extend network convergence time.
Conditions: This symptom is observed on a distributed router or switch such as a (Cisco Catalyst
6000 series, Cisco 7500 series, Cisco 7600 series, Cisco 10000 series, and Cisco 12000 series. The
symptom occurs when the router has the ip multicast-routing distributed command enabled for
any VRF and when a line card is reloaded more than 50 seconds into the 60-second MDFS
flow-control period.
Workaround: The symptom corrects itself after 60 seconds. Alternatively, you can enter the clear ip
mds linecard slot number command.
• CSCeh84233
Symptoms: After a manual switchover on a Cisco 12000 series that has two RPs that runs in RPR+
mode, some MLP bundles on a 1-port channelized OC-12 (DS1/E1) ISE line card may not forward
traffic.
Conditions: This symptom is observed on a Cisco 12000 series that runs the gsr-p-mz image of
Cisco IOS Release 12.0(28)S3.
Workaround: Enter the shutdown command followed by the no shutdown command on the MLP
interface.
• CSCeh84740
Symptoms: An RPR+ switchover may cause a VIP or line card to pause indefinitely.
Conditions: This symptom is observed when a high load of traffic passes through interfaces of a VIP
or line card when these interfaces are configured for QoS.
Workaround: There is no workaround.
• CSCeh96621
Symptoms: The line protocol of interfaces goes down, the router is unable to allocate further
resources, and the router generates the following error messages:
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial5/0.8/23:0, changed state to
down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial5/0.8/24:0, changed state to
down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Multilink11 0, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial5/0.8/25:0, changed state to
down
%EERP-2-UIDB_ERR: Unable to allocate resources. Invalid index for free 935
%EERP-2-UIDB_ERR: Unable to allocate resources. Invalid index for free 926
%EERP-2-UIDB_ERR: Unable to allocate resources. Invalid index for free 937 ...
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S3 when you use a script that adds and deletes a multilink configuration.
Workaround: There is no workaround.
• CSCeh97080
Symptoms: When Multiprotocol Label Switching (MPLS) is enabled on a router, one or more LDP
sessions may be disrupted during periods of extremely high CPU use.
