Displays IP statistics for the switch CPU or for a particular VLAN (Virtual LAN).
| name | Specifies a VLAN name. |
| vrname | Specifies a VR or VRF. |
N/A.
This command only shows statistics of the CPU-handled packets. Not all packets are handled by the CPU.
If you do not specify a VR or VRF, the command applies to the current VR context.
The fields displayed in the show ipstats command are defined in the following tables.

| Bad Proto | IP packets with unknown (not standard) upper layer protocol. |
| OutRequest | IP packets sent from upper layers to the IP stack. |
| OutDiscard | IP packets that are discarded due to lack of buffer space or the router interface being down, or broadcast packets with broadcast forwarding disabled. |

| Redirects | IP packets forwarded on the same network. |
| No route | Not used. |
| Bad TTL | IP packets with a bad time-to-live. |
| Bad MC TTL | IP packets with a bad multicast time-to-live. |
| Bad IPdest | IP packets with an address that does not comply with the IPv4 standard. |
| Blackhole | IP packets with a destination that is a blackhole entry. |
| Output err | Not used. This is the same as Fwd Err. |
| MartianSrc | IP packets with an invalid source address. |
Global ICMP Statistics Field Definitions
| Field | Definition |
|---|---|
| OutResp | Echo replies sent from the CPU. |

| InTooshort | Incoming ICMP packets that are too short. |
| Bad chksum | Incoming ICMP packets with checksum errors. |
| In Badlen | Incoming ICMP packets with length errors. |
| echo reply (In/Out): | ICMP “echo reply” packets that are received and transmitted. |
| destination unreachable (In/Out): | ICMP packets with destination unreachable that are received and transmitted. |
| port unreachable (In/Out): | ICMP packets with port unreachable that are received and transmitted. |
| echo (In/Out): | ICMP echo packets that are received and transmitted. |
Global IGMP Statistics Field Definitions
| Field | Definition |
|---|---|
| Out Query | Number of IGMP (Internet Group Management Protocol) query messages sent by the router. |
| Out Report | Number of reports sent on an active multicast route interface for reserved multicast addresses and for regular IGMP reports forwarded by the query router. |
| Out Leave | Number of IGMP out leave messages forwarded for IP multicast router interfaces. |
| In Query | Number of IGMP query messages received. |
| In Report | Number of IGMP report messages received (mostly from hosts). |
| In Leave | Number of IGMP leave messages received (mostly from hosts). |
| In Error | Number of IGMP packets with bad header fields or checksum failures. |
Router Interface Statistics Field Definitions
| Field | Definition |
|---|---|
| Packets IN/OUT | Total number of IP packets received or transmitted on a VLAN router interface. |
| Octets IN/OUT | Total number of octets received or transmitted on a VLAN router interface. |
| Mcast packets IN/OUT | Total number of multicast packets received or transmitted on a VLAN router interface. |
| Bcast packets IN/OUT | Total number of broadcast packets received or transmitted on a VLAN router interface. |
| Errors IN/OUT | Total number of IP packets with errors received or transmitted on a VLAN router interface. |
| Discards IN/OUT | Total number of IP packets that cannot travel up to the CPU due to lack of buffer space. |
| Unknown Protocols IN/OUT | Total number of IP packets with unknown upper layer protocols received by the router interface. |
The following example displays IP statistics for the VLAN "accounting":
show ipstats vlan accounting
This command was first available in ExtremeXOS 10.1.
The ipv4 keyword was added in ExtremeXOS 11.2.
