Low TCAM entries

[STUART KENDRICK]

I've just replaced a Cat6500 w/Sup 720 in a data center switch with a Sup2T ... and a few minutes after booting, it spat out:

%QM-4-TCAM_ENTRY: Hardware TCAM entry programming failed for slot 7 intf Gi4/39 dir IN: <CONFIG_UPDATE_REQ> TCAM Req Error: FAIL (4): Low TCAM Entries (1)

Hints on what this means?  The box has been running for several hours now, no further TCAM-related messages.

TCAM usage seems ... trivial to me:
