Dynamic troubleshooting

The Ethernet TAP probe provides troubleshooting utilities that let you test communications dynamically, without making any permanent changes to the flash EPROM of the Ethernet TAP probe. Any settings will be lost after the Ethernet TAP probe is reset.

Using host command

Use the host command to edit the host table by assigning hostnames to specific IP addresses without permanently storing the changes in the Ethernet TAP probe flash EPROM. When entered without options, the host command displays the current host table. See netparam (netparamadd_host) to permanently store an address in flash.

To add a hostname to the host table

Connect to the internal setup utility of Ethernet TAP probe, for more information, see Connecting to Ethernet TAP probe setup utility topic.
At the core> prompt, enter the host command by using this syntax:
```
host add 
hostname

ip_address
```

The system adds the specified hostname to the host table.

To remove hostname from host table

Connect to the internal setup utility of Ethernet TAP probe.
At the core> prompt, enter the host command by using this syntax:
```
host delete 
hostname

ip_address
```
The system removes the specified hostname from the host table.

Hostnames are also cleared from the host table after the Ethernet TAP probe is reset.
