Description: Remote MAC address count of this VXLAN.
What is h3cVxlanRemoteMacCount?
This value reports the number of remote MAC addresses currently known for a given VXLAN. An admin monitors it to watch for abnormal MAC table growth, which can indicate a Layer 2 loop or a MAC flooding condition within that overlay segment. For example, a count that suddenly jumps from a few hundred to several thousand entries would prompt an admin to investigate that VXLAN for a loop or attack.
Examples
