VLANs in a Converged Network A switch virtual interface (SVI) is a
VLAN of switch ports represented by one interface to a routing or
bridging system.VLAN There is one-to-one mapping between a VLAN and
SVI, thus only a single SVI can be mapped to a VLAN. In default
setting, an SVI is created for the default VLAN (VLAN1) to permit
remote switch administration. VLAN An SVI cannot be activated
unless associated with a physical port. 2006 Cisco Systems, Inc.
All rights reserved.Cisco PublicITE 1 Chapter 6 8 Explain the Role
of VLANs in a Converged Network SVIs are generally configured for a
VLAN for the following reasons: Allow traffic to be routed between
VLANs by providing a default gateway for the VLAN. Provide fallback
bridging (if required for non-routable protocols). Provide Layer 3
IP connectivity to the switch. Support bridging configurations and
routing protocol. 2006 Cisco Systems, Inc. All rights

mode dynamic auto This command makes the interface willing to
convert the link to a trunk link if the neighboring interface is
set to trunk or desirable mode. Otherwise, the link will become a
non-trunking link. 2006 Cisco Systems, Inc. All rights

20 Summary VLANS Allows an administrator to logically group devices
that act as their own network Are used to segment broadcast domains
Some benefits of VLANs include Cost reduction, security, higher
performance, better management 2006 Cisco Systems, Inc. All rights

a VLAN include Data Voice Network protocol Network management
Communication between different VLANs requires the use of Routers

Chapter 6 22 Summary Trunks A common conduit used by multiple VLANS
for intra-VLAN communication EEE 802.1Q The standard trunking
protocol Uses frame tagging to identify the VLAN to which a frame
belongs Does not tag native VLAN traffic 2006 Cisco Systems, Inc.
