Nov 27, 2020
- Cisco ASR 1000 Series Aggregation Services Routers
Known Affected Releases
Symptom: On an ASR1K series router, if IPSec is enabled, then cleartext traffic may be mis-classified and subsequently dropped when the HW TCAM resources are exhausted. Conditions: This occurs when the router falls back to using the SW TCAM. The following log messages can be seen before the failure: %CPP_FM-3-CPP_FM_TCAM_WARNING: SIP0: cpp_sp: TCAM limit exceeded: HW TCAM cannot hold Class group ipsec-rule:126.96.36.1996754945.
