If ping attempts to the SM100 IP address fail and the default gateway is incorrectly set, what action should you take?

Choosing to edit the SM Instance under SM Administration via Avaya Aura System Manager web GUI is the correct action to take when there are failed ping attempts to the SM100 IP address due to an incorrectly set default gateway. This is because the default gateway is a critical configuration parameter that directs network traffic from the Session Manager (SM) to the appropriate external networks. If the default gateway is not set correctly, the Session Manager won’t be able to communicate with other devices on the network, which will result in ping failures.

By accessing the SM Administration section through the Avaya Aura System Manager, you can review and modify the settings for the SM Instance, including the default gateway. Correcting any misconfiguration here is essential for re-establishing proper network connectivity, thereby resolving the ping failure issue.

While other actions may also be relevant for network management or troubleshooting, they do not address the immediate need to correct the gateway settings. For instance, executing runsmconsole or SMnetSetup might offer additional diagnostic or configuration options, but they wouldn't directly allow you to specify the correct default gateway setting. Editing the SIP Entity screen pertains to routing and entity configuration rather than the direct issue with the default gateway, which makes it less appropriate in this context.
