To view ARP entry information, use the following command:
Admin@nodename> show network arp
You can filter the displayed entries using these filtering options:
|
Parameter |
Description |
|---|---|
|
node-name |
The name of the cluster node whose ARP entries need to be displayed. Next, specify the interface name or host IP address: Admin@nodename> show network arp node-name <node-name> interface <iface-name> Admin@nodename> show network arp node-name <node-name> host <ip> |
|
interface |
The NGFW interface name. |
|
host |
The IP address of the device. |
|
mac |
The MAC address of the device. |
Admin@nodename> show network arp host <IP-address> Admin@nodename> show network arp interface <interface-name> Admin@nodename> show network arp mac <MAC-address>
You can also view ARP entries in the configuration mode. The commands are identical to those used in the diagnostics and monitoring mode.
Static ARP entries can be added in the configuration mode using the following command:
Admin@nodename# set network arp host <IP-address> interface <interface-name> mac <MAC-address>
Command parameters:
|
Parameter |
Description |
|---|---|
|
node-name |
The name of the cluster node on which the ARP entry will be created. Next, specify the interface name and the IP and MAC addresses of the device. |
|
interface |
The NGFW interface name. |
|
host |
The IP address of the device. |
|
mac |
The MAC address of the device. |
The commands for deleting system and static ARP entries have a similar structure and differ only in the action to be taken:
-
clear: delete system records in the diagnostics and monitoring mode
-
delete: delete static records in the configuration mode.
The format of the deletion commands is shown below using diagnostics and monitoring commands as an example.
To delete a system entry:
Admin@nodename> clear network arp interface <iface-name> host <ip>
To delete an entry on a different cluster node:
Admin@nodename> clear network arp interface <iface-name> node-name <node-name> host <ip>
The following command deletes all system records on the specified interface(s):
Admin@nodename> clear network arp interfaces [ <iface-name1> <iface-name2> ... ]
To delete all system entries for an interface on a different node:
Admin@nodename> clear network arp interfaces [ <iface-name1> <iface-name2> ... ] node-name <node-name>
