• When a logical trunk port is enabled, all members of the trunk are enabled for RA Guard. Likewise, when a logical trunk port is disabled (no ipv6 ra-guard ports <trunk-port> ), all members of the trunk are disabled for RA.

• When ports are configured for RA Guard, hardware resources are allocated. If there are not enough hardware resources, this message displays:Commit failed

• When debug logging is enabled (ipv6 ra-guard ports <port-list> log), the RA and redirect packets are sent to the processor, which can be CPU-intensive. This message displays:The log option uses a lot of CPU and should be used only for short periods of time.
