Displays the IP Address Resolution Protocol (ARP) table. You can filter the display by IP address, MAC address, VLAN (Virtual LAN), or permanent entries.
| ip_addr | Specifies an IP address. |
| mac | Specifies a MAC address. |
| vlan_name | Specifies a VLAN name. |
| vlan_list | Specifies a VLAN list of IDs. |
| permanent | Specifies permanent entries. |
| port | Show entries for a specific port. |
| port | Show only entries for this port number. |
| vr_name | Specifies a VR or VRF. |
Show all entries, except for proxy entries.
If you do not specify a VR or VRF, the command applies to the current VR context.
The show output displays the following information:
| ARP address check | Whether IP ARP checking is enabled or disabled. IP ARP checking verifies if the ARP request‘s source address is in the receiving interface‘s subnet. |
| ARP refresh | Whether ARP refresh is enabled or disabled. ARP refresh is performed when an ARP entry‘s age is three-fourths of the timeout value. |
| Distributed mode | The Configured field shows the feature state that will apply the next time the switch is restarted. The Current state shows the current state that was applied the last time the switch was restarted. |
| Dup IP Addr | IP addresses that have been used by other hosts on the network. |
| Dynamic entries | The number of dynamic (learned ARP) entries in the table. |
| Failed requests | The number of failed ARP requests sent (by this VR or VRF). |
| In Request | The number of ARP request packets received (by this VR or VRF). |
| In Response | The number of ARP reply packets received (by this VR or VRF). |
| Max ARP entries | Maximum ARP table size for the VR or VRF (each VR has its own ARP table). |
| Max ARP pending entries | Maximum number of incomplete (pending) ARP entries allowed in the table. |
| Out Request | The number of ARP request packets sent (by this VR or VRF). |
| Out Response | The number of ARP reply packets sent (by this VR or VRF). |
| Pending entries | The number of sent ARP requests that have not yet received a response. |
| Proxy Answered | The number of ARP requests answered by the ARP proxy. |
| RX Error | The number of incorrect ARP request and reply packets received. The malformed packets include the following errors: incorrect ARP op code, hardware address type is not Ethernet, the protocol address is not IP, and similar errors. |
| Static entries | The number of configured (static ARP) entries in the table. |
| Rejected Count | The number of rejected ARP request packets. |
| Rejected I/F | The VLAN on which the last rejected ARP request packet arrived. |
| Rejected IP | The source address for the last rejected ARP request. An example reason for an ARP request packet to be rejected is if the source address of the packet is not in the subnet. |
| Rejected Port | The port on which the last rejected ARP request packet arrived. |
| Timeout | Timeout value for a dynamic (learned) ARP entry. |
The following example displays the IP ARP table for the current VR or VRF context:
