Cat6500 with SUP720-3B NAT performance figures

Here's a little query I had about performance figures for a Cat6500 with the SUP720-3B. The answers and some transcript is below:

Regarding static NAT on the Catalyst 6500 with Sup 720, we do not recommend configuring large numbers of static NAT entries on Supervisor 720 (100-200 entries is a safe ballpark figure, and should be adequate for most deployments).

Since NAT uses the NetFlow TCAM to store its entries, the total number of NAT entries depends on the forwarding engine being used :

Non-XL – 512K (Ingress / Egress)

XL – 512K Ingress, 512K Egress

The non-XL TCAM is shared for both directions, while the XL TCAMs are unique to each direction.
