Hello
I'd like to know what is "masks" in the output of show platform tcam utilization.
What does 784 mean? What effect has the number of mask in the amount of supported unicast direct routes?
I'm having trouble comparing the capacity of theese two switches, regarding unicast directly-connected routes.
I know the second switch has cpu utilization issues and ip unicast failed routes over 4096 arp entries. What would be the case for the first one?
Switch 1:
CAM Utilization for ASIC# 0 Max Used
Masks/Values Masks/values
Unicast mac addresses: 784/6272 12/26
IPv4 IGMP groups + multicast routes: 144/1152 6/26

IPv4 unicast indirectly-connected routes: 272/2176 8/44

Thanks.
