[c-nsp] TCAM at Cat4500 Sup6E

[Dmitry Kiselev]

Hello!

Could anybody clear me with TCAM on Cat4500 Sup6E?
Or Cat4900M as it is Sup6E based.

There are 64 TCAM blocks. Each of them can be DYNAMICALY
configured as 80 or 160-bit with 4096 and 2048 entries
accordingly.  IPv4 and IPv6 FIBs are builded DYNAMICALY
using one or more TCAM blocks. Additional TCAM blocks
are configured to apropriate bit-size and used if new FIB
entry is learned and all previously allocated TCAM already
used.  There are no stuff like "mls cef maximum-routes" or
"sdm template" to preconfigure TCAM allocations.

Am I right?

How about optimizing TCAM blocks usage while freeing FIB
entries?   Any other TCAM related caveats?
