OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S6
Conditions: This symptom is observed on a Cisco platform when an SSO switchover occurs.
Workaround: There is no workaround.
• CSCsb53420
Symptoms: Cell loss occurs when bursty VBR ATM traffic is sent through a Cisco 12000 series
4-port ATM OC-12 ISE line card via an L2TPv3 IP tunnel to another 4-port ATM OC-12 ISE line
card on another Cisco 12000 series and when the VBR traffic is sent at rates lower than what is
configured on the routers (that is, at about 50 percent of the OC-12 line rate).
Conditions: These symptoms are observed on a Cisco 12000 series that is connected back-to-back
via an OC-192 or OC-48 POS link to another Cisco 12000 series.
Workaround: There is no workaround.
• CSCsb59555
Symptoms: An Engine 3 or Engine 4+ line card may be stuck in the “request reload” state and CEF
may be disabled on the line card, although the CEF table is up, as is shown in the output of the show
cef linecard command:

Conditions: This symptom is observed on a Cisco 12000 series after an RPR+ switchover has
occurred. However, the symptom is platform-independent and may also occur on another platform
that is configured for CEF when an RPR+ switchover has occurred.
Workaround: Enter the clear cef linecard command for the affected line card.
