Preparing a Power Systems compute node for network topology

Use the following steps to prepare your Power Systems™ compute node to support network topology.

Before you begin

Links are added to the network topology either dynamically by IBM® Flex System Manager Network Control or manually by a user. You can take advantage of dynamic link discovery by enabling Link Layer Discovery Protocol (LLDP) on s. Power® VIOS has native support for LLDP, but LLDP is not started by default. Perform the following steps to enable LLDP on your :

Procedure

Run the following command to log in to the VIOS server and escape to the root access:
```
oem_setup_env
```
If you are configuring the Shared Ethernet Adapter for VEPA functionality that provides Qbg support, skip this step. Otherwise, you need to restart the daemon with the -A option to keep the 'lldpd' service running. Run the following command to verify that the lldpd daemon is up and running with the -A option:
```
ps -ef | grep -i lldpd
```
1. If the lldpd daemon is not started with the -A option, kill the process and restart the daemon using the following command:
```
lldpd -A
```
Run the following command to obtain a list of devices and find out the shared ethernet adapters:
```
lsdev
```
For each such shared ethernet adapter found in the previous step, run the following command to update the lldpsvc attribute:
```
chdev -l ent2 -a lldpsvc=yes
```
Note: Replace ent2 with the interface device from your environment.
