This section identifies the features associated with Layer 2:
|
||
|
||
MAC Layer
|
||
---------
|
||
* Ethernet
|
||
|
||
Discovery
|
||
---------
|
||
* Cisco Discovery Protocol
|
||
* Link Layer Discovery Protocol (LLDP)
|
||
|
||
Link Layer Control Protocol
|
||
---------------------------
|
||
* Bit Index Explicit Replication – Link Layer Multi-cast forwarding.
|
||
* Link Layer Control (LLC) - multiplex protocols over the MAC layer.
|
||
* Spatial Reuse Protocol (SRP)
|
||
* High-Level Data Link Control (HDLC)
|
||
* Logical link control (LLC)
|
||
* Link Agg Control Protocol (Active/Active, Active/Passive) – 18.04
|
||
|
||
Virtual Private Networks
|
||
------------------------
|
||
* MPLS
|
||
|
||
* MPLS-o-Ethernet – Deep label stacks supported
|
||
|
||
* Virtual Private LAN Service (VPLS)
|
||
* VLAN
|
||
* Q-in-Q
|
||
* Tag-rewrite (VTR) - push/pop/Translate (1:1,1:2, 2:1,2:2)
|
||
* Ethernet flow point Filtering
|
||
* Layer 2 Cross Connect
|
||
|
||
Bridging
|
||
---------
|
||
* Bridge Domains
|
||
* MAC Learning (50k addresses)
|
||
* Split-horizon group support
|
||
* Flooding
|
||
|
||
ARP
|

||
Integrated Routing and Bridging (IRB)
|
||
-------------------------------------
|
||
* Flexibility to both route and switch between groups of ports.
|
||
* Bridged Virtual Interface (BVI) Support, allows traffic switched traffic to be routed.
