CSCtr98532
Symptoms: A Cisco 12000 series router that is running a Cisco IOS 12.0(32) SY6 image or later and
that has an Engine 5 linecard and channelized SPAs might occasionally see a spurious SPA reload
or linecard reload.
that has an Engine 5 linecard and channelized SPAs might occasionally see a spurious SPA reload
or linecard reload.
Conditions: This issue is seen only with channelized SPAs (1xCHOC3, 4xCT3, or 8xCHT1/E1) and
when the Control Plane Policing feature is configured. If the CoPP configuration is configured to
examine Layer 4 headers (for example, TCP, UDP, or ICMP), the issue might be seen. The issue is
seen along with the L3VPN over IP feature.

Workaround: There is no workaround. The issue is very random in nature and is dependent on
network configuration.

CSCtg41086
Symptoms: A customer observed multiple errors on the E1 on the Cisco 7206 side, which caused
the interface to bounce continuously. The customer created a test VC on the Cisco 12000 SPA and
measured its clocking in comparison to the ethalon. The difference was with an accuracy of 10^-3,
but it should be at least 10^-6. Further tests showed that the E1 on the Cisco 12000 takes clocking
from the SPA card, although it should take clocking from the SIP linecard backplane.

Conditions: A Cisco 12000 with an SPA-1XCHSTM1/OC3 that is used for channelized E1.
Workaround: Turn the synchronization around in order for the other side to be the clocking source.

Symptoms: A Cisco 12000 router may retain the old label for a VPNv4 route when the primary route
has disappeared.

Conditions: This problem occurs when multiple routes for the same VPNv4 prefix exist and they all
have the same next hop. You also need to have the ip cef table loadinfo force command configured
on the router.

on the router.
Workaround: Clear the affected route to recover from the problem.

CSCth90331
Symptoms: Interface flaps on an ISE ATM LC running Cisco IOS Release 12.0(32) SY11 cause a
leak in the encapsulation table (“show gsr ha encap-table slot3” for that LC, and the encapsulation
table will fill up). When that happens, any interface that flaps or is bounced will not be able to pass
outbound traffic.

table will fill up). When that happens, any interface that flaps or is bounced will not be able to pass
outbound traffic.
To see the encapsulation table, issue the “show gsr ha encap-table slot#” command. If the table is
full, every entry will be FFFFFFFF.
