I was LAB testing a 2960X for routing in small sites.
During the test I configured multiple SVIs and the maximum (16) static routes.
While I was doing this I recieved follwing log message:
%PLATFORM_UCAST-4-PREFIX: One or more, more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded
Looks like the IPv4 unicast indirectly-connected routes were at its maximum:
2960X#show platform tcam utilization
CAM Utilization for ASIC# 0 Max Used
Unicast mac addresses: 4316/4316 38/38
IPv4 IGMP groups: 368/368 1/1
IPv4 unicast directly-connected routes: 848/848 9/9
IPv4 unicast indirectly-connected routes: 80/80 79/79
IPv6 Multicast groups: 320/320 11/11
IPv6 unicast directly-connected routes: 816/816 0/0
IPv6 unicast indirectly-connected routes: 32/32 3/3
IPv4 policy based routing aces: 32/32 12/12
IPv4 qos aces: 384/384 42/42
IPv4 security aces: 384/384 44/44
IPv6 policy based routing aces: 16/16 8/8
IPv6 qos aces: 128/128 32/32
IPv6 security aces: 256/256 17/1
What is included in the "IPv4 unicast indirectly-connected routes"?
As obviously I don't have 80 SVIs and or static routes.
