Configuration Considerations for Forwarding Profiles

The following configuration considerations apply to forwarding profiles:
  • Forwarding profiles are only supported on ICX 8200, ICX 8100, ICX 7850, and ICX 7550 devices.
  • The UFT is configured during the initialization process. The configuration is based on the forwarding profile selected.
  • When the forwarding profile is changed using the forwarding-profile command, the maximum system parameters for IPv4 routes, IPv6 routes, MAC addresses, IGMP groups, MLD groups, PIM mcache, PIMv6 mcache, and next hops take the value from the configured profile. The IP route default VRF, IP route VRF, IPv6 route VRF, and IPv6 default VRF are reset.
  • The default forwarding profile is profile1.
  • For ICX 7850 devices, there are four profiles available. For ICX 8200, ICX 8100, and ICX 7550 devices, for router images, there are three profiles available.
  • When uRPF is enabled, IPv4 route and IPv6 route scaling numbers are reduced.
  • In previous FastIron releases that supported a UFT, the Layer 2 table and Layer 3 table sizes were fixed and the UFT partition could not be changed.
  • The UFT shared table partition can be changed only during the initialization process. The selected forwarding profile is available after a reload.
  • When profile3 (SP: Service provider) is used for ICX 7850 devices, PIMv4 and PIMv6 can simultaneously scale to 8192 mcache entries each.
  • For ICX 8200 devices, non-optimization of Multicast snooping and Routing is not supported for Profile 3.
