Networking > Integrated cisco and unix network architectures > Chapter 5. Ethernet and VLANs

This chapter deals with all issues and aspects of Ethernet network interface cards (NICs) with regard to the physical and data link layers. It discusses card-specific aspects such as Media Access Control (MAC) address modification, cabling issues, hardware virtual LAN (VLAN) support, as well as aspects of the OS-specific IP stacks such as IP aliases, 802.1Q VLAN support, and bridging modes of operation.

The second half of this chapter investigates the capabilities of these interfaces when connected to switches, routers, or other UNIX gateways. The chapter concludes with a discussion of bridge and VLAN security, Ethernet channel bonding, and some hands-on labs.
