Running tcpdump on the device i'm trying to ping, there are ARP requests and replies. But the replies are never received by the target, arp -a shows <incomplete>. Looking at the stats counters in debugfs, the packets are counted in in_unicast, but also sw_in_filtered. Port 0 is lan0 and port 5 is the cpu port. root@370-rd:/sys/kernel/debug/dsa0# cat regs GLOBAL GLOBAL2 SERDES 0 1 2 3 4 5 6 0: c874 0 1940 1d0f 1d0f 1d0f 1d0f 100f e07 6 1: fa0 0 149 3 3 3 3 3 c03e 3 2: fa0 ffff 141 0 0 0 0 0 0 0 3: 0 ffff ea1 1721 1721 1721 1721 1721 1721 1721 4: 6000 258 1e0 433 433 433 433 433 373f 433 5: 3000 ff 0 0 0 0 0 0 0 0 6: fa0 1f0f 4 7f 7e 7d 7c 7b 7a 79 7: 3331 707f 2001 0 fa1 fa2 fa3 fa4 0 fa6 8: 303 7800 0 2c80 2c80 2c80 2c80 2c80 2c80 2c80 9: 0 1600 0 1 1 1 1 1 1 1 a: 148 0 0 0 0 0 0 0 0 0 b: 2000 1000 0 1 2 4 8 10 2000 40 c: f0f 7f 0 0 0 0 0 0 0 0 d: 0 5f1 3 0 0 0 0 0 0 0 e: 0 0 0 0 0 0 0 0 0 0 f: 0 f00 c000 dada dada dada dada dada dada dada 10: 0 0 4005 0 0 0 0 0 0 0 11: 0 0 8000 0 0 0 0 0 0 0 12: 5555 0 0 12 0 0 0 0 8 0 13: 5555 0 0 0 0 0 0 0 22 0 14: aaaa 400 0 0 0 0 0 0 0 0 15: aaaa 0 0 0 0 0 0 0 0 0 16: ffff 0 1 700f 7002 7004 7008 33 33 0 17: ffff 0 0 0 0 0 0 0 0 0 18: fa41 15f6 0 3210 3210 3210 3210 3210 3210 3210 19: 0 0 0 7654 7654 7654 7654 7654 7654 7654 1a: 5550 0 42 0 0 0 0 0 0 0 1b: 1fa f869 0 8000 8000 8000 8000 8000 8000 8000 1c: 0 0 0 0 0 0 0 0 0 0 1d: 5ce0 0 0 0 0 0 0 0 0 0 1e: 0 0 0 0 0 0 0 0 0 0 1f: 0 0 0 0 0 0 0 0 0 0 Andrew
