Use of SDLC at the data link layer permits 250 nodes on one segment with a total distance of 13.2 km.
Survivability can be addressed in many layers in a network and protection can be performed at the physical layer (SONET/SDH, Optical Transport Network), Layer 2 (Ethernet, MPLS) and Layer 3 (IP).
VSP 4850GTS, a 1RU Layer 2/Layer 3 Switch that is equipped with 48 10/100/1000 Ethernet ports (including two common ports offering SFP connectivity) plus 2 10 Gigabit Ethernet ports that feature SFP+ physical connectivity.
An individual certified in CCIE Storage will be highly skilled with LANs, MANs and WANs over Fibre Channel, iSCSI, FCIP and FICON, and must demonstrate in-depth understanding of layer 2 and layer 3 network infrastructures.
Some of these applications are in varying levels of commercialization, such as IPv6, open-source middleware for secure network access, Layer 2 VPNs and dynamic circuit networks.
Link-local addresses, which are intended only for use in the local layer 2 domain
The Nortel Discovery Protocol (NDP) is a Data Link Layer (OSI Layer 2) network protocol for discovery of Nortel networking devices and certain products from Avaya and Ciena.
