Feature Comparison

The following sections describe some general featuredifferences between CatOS and Cisco IOS Software. This isnot

an exhaustive or detailed list of features and their operation, but simply a comparison between the implementation

and CLI syntax of some commonly used features onthe CiscoCatalyst 6500.For amore detailedfeature description

of all CatOS and Cisco IOS features, refer to the user documentation at:

VLAN Trunking Protocol

VTP is used to manage VLAN information among switches ina Layer 2domain. Administration ishandled between

VTP Servers and VTP clients so that a common VLAN topology is known throughout the network. A device can

alternatively be conﬁgured as a VTP transparent device; in which case, the device will not participate in the VTP

protocol but can forward VTP advertisements. The only difference in VTP functionality between CatOS and Cisco

IOS Software is that CatOS allows VTP to be disabled completely (for example, the device does not forward VTP

advertisements in the “off” mode).

For Cisco IOS Software, VTP/VLAN conﬁgurations are performed in global conﬁguration mode for VTP

Transparent, VTP Client, and VTP Server systems

. This example compares how to deﬁne the VTP domain, mode,

and VLANs and then apply them to ports:

VTP Operation in Cisco IOS Software

Conﬁguration changes in CatOS are written to NVRAM immediately after a change is made. In contrast, the Cisco

IOS Software does not save conﬁguration changes to NVRAM unless you issue the copy run start command. VTP

Client and Server systems require that VTP updates from other VTP servers be immediately saved in NVRAM

without user intervention. Thus, the VTP update requirements are met by the default CatOS operation; while the

Cisco IOS update model requires an alternative update operation.

3. VLAN or VTP conﬁguration does not have to be completed in VLAN database submode.
