Description: The number of FFT cache misses (i.e how many times did the cache gate have to do a look up in the RNP because the FFT didn't have the destination network
What is wfIpv6IfStatsCacheMisses?
Count of misses in this Wellfleet router's per-interface forwarding cache (the 'FFT'), i.e. how many times the router had to fall back to a full routing-table (RNP) lookup because the fast-path cache didn't have an entry for the destination network. A high miss rate signals the forwarding cache (sized via wfIpv6IfFwdCacheSize) may be too small or too frequently flushed for this interface's traffic pattern.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.16.1.1.5.1.16 snmpwalk -v2c -c public <target> Wellfleet-IPV6-MIB::wfIpv6IfStatsCacheMisses
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.16.1.1.5.1.16.1 snmpget -v2c -c public <target> Wellfleet-IPV6-MIB::wfIpv6IfStatsCacheMisses.1
