What Information Do SD-WAN Show Commands Provide?
With SD-WAN show commands, you can view various information about a SD-WAN. For example, you can view the number and percentage of sessions that have been distributed to each tunnel member of a virtual SD-WAN interface.
You can also use show commands to view global counters, for troubleshooting purposes. For example, you can verify that the number of SD-WAN probe Request packets received on a hub equals the number of probe Reply packets sent.
Show commands also allow you to view VPN tunnel information. For example, you can view all the tunnels created on a firewall as well as details about them.
Viewing BGP (Border Gateway Protocol) data is another type of information that show commands provide. For example, you can view a BGP summary for a virtual router.
Finally, you can use show commands to view SD-WAN interface information. For example, you can view the SD-WAN interfaces in the forwarding information base (FIB).
