  • Cisco ASR 9000 Series Aggregation Services Routers

Known Affected Releases

4.3.2.BASE

Description (partial)

Symptom:
Trying to apply a new ACL to an interface but the configuration is rejected with the following error
'prm_server' detected the 'warning' condition 'NP resource exhausted.'

Conditions:
A new ACL being applied to the interface/NP (once an ACL is applied to a particular NP adding that ACL to another int or sub-int on the same NP will NOT result in more TCAM entries being utilized).
Note: Bundles and other virtual interfaces such as tunnel-ip interfaces work different as they need to be programmed on multiple NPs.

The new ACL being applied would utilize fewer TCAM entries than are available, hence 'ample TCAM entries available'.
