0x806 port 1-12 permit
correct Source MAC in the Ethernet frame can pass
through the switch.
Step 3:
create access_profile profile_id 2
profile_name 2 packet_content_mask
offset_chunk_1 3 0xFFFF
offset_chunk_2 7 0xFFFF
offset_chunk_3 8 0xFFFF0000
Create access profile 2
The first chunk starts from Chunk 3 mask for Ethernet
Type. (Blue in Table 6, 13th and 14th bytes)
The second chunk starts from Chunk 7 mask for
Sender IP in ARP packet. (Green in Table 6, 29th and
30th bytes)
The third chunk starts from Chunk 8 mask for Sender
IP in ARP packet. (Brown in Table 6, 31st and 32nd
bytes)
Step 4:
config access_profile profile_id 2
add access_id 1 packet_content
offset_chunk_1 0x00000806
offset_chunk_2 0x00000A5A
offset_chunk_3 0x5A5A0000 port 1-12
deny
Configure access profile 2.
The rest of the ARP packets whose Sender IP claim
they are the gateway’s IP will be dropped.
Step 5:
save
Save configuration.
