Last Updated
Sep 03, 2026
MAC Scaling by ICX Device MAC Scaling by ICX Device MAC Scaling by ICX Device All ICX devices support 256 MAC match statements per ACL and 3,072 filter statements per device. Hardware scaling allows for the following number of filter statements per device: ICX 7150: 256 ICX 7250: 3,072 ICX 7450: 2,816 ICX 7550: 2,048 ICX 7650: 1,536 ICX 7750: 2,048 ICX 7850: 1,536 By default on all platforms, 30 entries are reserved in the Layer 2 ingress group.
