I have a 6500 running CATOS 8-5-8 where we have had to configure Permanet CAM entries due to issues with the Checkpoint ClisterXL 'Float' IP MAC Address.
What I need to know is how is the number of Permanent CAM entries calculated.
If you do a 'show cam permanent' the entries are displayed by VLAN. So therefore the number of CAM entries displayed matches the VLANS with Permanent CAM's configured.
However is the total number of Permanent CAM's on the Switch equal to one entry per VLAN per Port or just one entry per VLAN regardless of how many Ports have the MAC assigned to it.
i.e if you have 44 VLAN's each with one Permanent CAM assigned to 4 interfaces does this equate to a total of 176 entries on the Switch or is this just calculated as 44 entries
The primary reason for the question is that CATOS 8-5-8 only supports 256 Static/Permanet CAM entries and I am trying to figure out if I am getting close to the max.
