Enable Layer 2 Protocol Tunneling; Specify A Destination Mac Address For Bpdus; Rate-Limit Bpdus On The E-Series; Rate-Limit Bpdus On The C-Series, S-Series, And Z-Series - Dell Force10 Z9000 Configuration Manual

Enable Layer 2 Protocol Tunneling

Step Task
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.
3 Tunnel BPDUs the VLAN.

Specify a Destination MAC Address for BPDUs

By default, FTOS uses a Dell Force10-unique MAC address for tunneling BPDUs. You can configure
another value.
Task
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

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.
Task
Set a maximum rate at which the RPM will process BPDUs for
L2PT.
Default: 75 pps
E-Series Range: 75 to 3000 pps

Rate-limit BPDUs on the C-Series, S-Series, and Z-Series

CAM space is allocated in sections called Field Processor (FP) blocks.
