Service Provider Bridging
Service provider bridging is composed of virtual local area network (VLAN) Stacking, Layer 2 Protocol Tunneling, and
Provider Backbone Bridging as described in the
This chapter includes command line information (CLI) for the Dell Force10 operating software (FTOS) Layer 2 Protocol
Tunneling (L2PT). L2PT enables protocols to tunnel through an 802.1q tunnel.
L2PT is supported by FTOS on the C-Series, E-Series, S-Series, Z-Series, or S4810 Dell Force10 systems. L2PT is
supported on E-Series ExaScale with FTOS 8.2.1.0. and later.
For more information, refer to
Important Points to Remember
•
L2PT is enabled at the interface VLAN-Stack VLAN level. For more information about Stackable VLAN (VLAN-
Stacking) commands, refer to
•
The default behavior is to disable protocol packet tunneling through the 802.1q tunnel.
•
Rate-limiting is required to protect against bridge protocol data units (BPDU) attacks.
•
A port channel (including through link aggregation control protocol [LACP]) can be configured as a VLAN-Stack
access or trunk port.
•
Address resolution protocol (ARP) packets work as expected across the tunnel.
•
Far-end failure detection (FEFD) works the same as with Layer 2 links.
•
Protocols that use Multicast MAC addresses (for example, open shortest path first [OSPF]) work as expected
and carry over to the other end of the VLAN-Stack VLAN.
debug protocol-tunnel
Enable debugging to ensure incoming packets are received and rewritten to a new MAC address.
C-Series, E-Series, S-Series, Z-Series, S4810
Syntax
debug protocol-tunnel interface {in | out | both} [vlan vlan-
id] [count value]
To disable debugging, use the no debug protocol-tunnel interface {in |
out | both} [vlan vlan-id] [count value] command.
