Enable Layer 2 Protocol Tunneling
Specify a Destination MAC Address for BPDUs
By default, FTOS uses a Dell Networking-unique MAC address for tunneling BPDUs. You can configure
another value.
Rate-limit BPDUs on the S-Series, and Z-Series
CAM space is allocated in sections called Field Processor (FP) blocks.
There are total 13 user-configurable FP blocks on the S-Series. The default number of blocks for L2PT is
0; you must allocate at least one to enable BPDU rate-limiting.
Step Task Command Syntax Command Mode
1 Verify that the system is running the default CAM profile;
you must use this CAM profile for L2PT.

2 Enable protocol tunneling globally on the system. protocol-tunnel enable CONFIGURATION
3 Tunnel BPDUs the VLAN. protocol-tunnel stp INTERFACE

Task Command Syntax Command Mode
Overwrite the BPDU with a user-specified destination
MAC address when BPDUs are tunneled across the
provider network.
Default: 01:01:e8:00:00:00

CONFIGURATION
Step Task Command Syntax Command Mode
1 Create at least one FP group for L2PT. Refer
