The three components of AVVID are Network Infrastructure, Intelligent Network Services, and Network Solutions.
When cabling Ethernet connections, do not exceed more than 5 meters between the user's PC and his outlet or punch-down block, 90 meters between here and the patch panel, and 5 meters from the patch panel to the Ethernet switch.
Use the Catalyst 3550 for the Campus Core and the 2950 for the Building Access. Use the Catalyst 4000s or 3500XL for the Building Access, the 4006 for the Building Distribution, and either the 4006 or 6500 for the Campus Core. Use the Catalyst 4000s or 6500 for the Building Access, 4006 or 6500 for the Building Distribution, and 6500s for the Campus Core.
CatOS is supported on the Catalyst 4000s and 6500s, and provides only Layer 2 processing. Hybrid mode is supported on the 4006 and 6500 when a routing card is installed the routing card has IOS and the Supervisor Engine has CatOS. Native mode only runs IOS, controlling both Layer 2 and Layer 3 functions. The CatOS uses set and clear commands to make configuration changes.
In-band management is where your management traffic, such as telnetting to the switch, crosses the switching backplane of the switch. Out-of-band management traffic doesn't traverse the backplane of the switch.
The SFM expands the backplane of the switch from 32 to 256Gbps. In a 6513, it goes in slots 7 or 8, whereas in others, it goes in slots 5 or 6.
To create a logical VLAN interface, use the interface vlan command and specify the VLAN that the switch should be associated with. Then assign an IP address to it with the ip address command. By default, these logical interfaces are disabled, so enable them with the no shutdown command.
