| Item | Description |
|---|---|
| Sent Packet Statistics | Statistics about sent packets. |
| Packet Check | Packet check. |
| Type | Type of statistics collection. |
| NS | Number of NS messages. |
| NA | Number of NA messages. |
| RS | Number of RS messages. |
| RA | Number of RA messages. |
| Total | Total number of packets. |
| Source mac rate-limit | Source MAC anti-attack rate limit. |
| Source ip rate-limit | Source IP anti-attack rate limit. |
| Source IP | Source address of ND messages, which is used for neighbor discovery. |
| Unspecified | Number of packets with unspecified source addresss. |
| Destination IP | Outer destination address of ND messages, which is used for packet forwarding. |
| Destination ip rate-limit | Destination IP anti-attack rate limit. |
| Unicast | Unicast address. |
| Multicast | Multicast address. |
| Target IP | Inner destination address of ND messages, which is used for neighbor discovery. |
| Target ip rate-limit | Target IP anti-attack rate limit. |
| Linklocal | Link-local address. |
| Global | Global unicast address. |
| Global rate-limit | Rate limit for packet receiving. |
| Received Packet Statistics | Statistics about received packets. |
| ND_MISS | Number of ND Miss messages. |
| Recv Total | Number of received packets. The value of Recv Total is the sum of Valid Total and Total in Dropped Packet Statistics. |
| Valid Total | Number of valid packets. In the scenario where rate limiting is based on ND Miss messages, if ND entries (incomplete entries) exist, the device continues to send ND Miss messages. These messages are received but not processed, and are counted into Valid Total. |
| Dropped Packet Statistics | Statistics about dropped packets. |
| Checksum error | Checksum error. |
| Bad length | Incorrect packet length. |
| Bad code | Incorrect packet code. |
| Bad hoplimit | Incorrect hop limit. |
| Bad source mac | Incorrect source MAC address in the Layer 2 header. |
| Bad destination mac | Incorrect destination MAC address in the Layer 2 header. |
| Bad source ip | Incorrect source IP address. |
| Bad destination ip | Incorrect destination IP address. |
| Bad target ip | Incorrect target IP address. |
| Bad option | Incorrect packet option. |
| Bad target mac | Incorrect target mac address in the ND message option. |
| Anti-attack | Attack defense check. |
| Nd validate mac-check | Source MAC address consistency check on ND messages. |
| Nd source mac check | Nd source mac check. |
| Interface source ip rate-limit | Interface source IP anti-attack rate limit. |
| Interface rate-limit | Interface ND packet type or ND Miss message anti-attack rate limit. |
| LR rate-limit | LR ND packet type or ND Miss message anti-attack rate limit. |
