Global configuration
By default, the device enables Layer 2 protocol forwarding (L2PF). Customer-BPDU packets on all
CVLANs are forwarded to provider network ports when they arrive at customer-edge ports.
Since L2PF is globally enabled by default, all CVLANs have L2PF enabled by default. No CLI
configuration is needed.
To globally disable Layer 2 protocol forwarding, enter the following command:
Brocade(
config)# no l2protocol-forwarding stp
To disable L2PF on a particular CVLAN, enter commands such as the following:
Brocade(config)#esi acme encapsulation cvlan
Brocade(config-abc)#vlan 10
Brocade(config-abc-vlan-10)# no l2protocol-forward stp
Syntax: [no] l2protocol-forwarding stp
Use the no parameter to disable Layer 2 protocol forwarding.
