Dynamic Counters
By default, counting is enabled for IPFLOW, IPACL, L2ACL, L2FIB.
For the remaining applications, Dell Networking OS automatically turns on counting when you enable the
application, and is turned off when you disable the application.
NOTE: If you enable more than four counter-dependent applications on a port pipe, there is an impact on
line rate performance.
The following counter-dependent applications are supported by Dell Networking OS:
Egress VLAN
Ingress VLAN
Next Hop 2
Next Hop 1
Egress ACLs
ILM
IP FLOW
IP ACL
IP FIB
L2 ACL
L2 FIB
