Enable Layer 2 Protocol Tunneling
Specify a Destination MAC Address for BPDUs
By default, FTOS uses a Force10-unique MAC address for tunneling BPDUs. You can configure another
value.
Rate-limit BPDUs on the E-Series
In order to rewrite the destination MAC address on BPDUs, they are forwarded to the RPM. You can
rate-limit BPDUs to protect the RPM, in which case the system drops BPDUs when the threshold is
reached.
