On one switch i have native vlan 114<br />
<br />
i should do the same think on the other switch as well , right ?

Yes, you would want to have the same vlans defined on both switches. &nbsp;That's the point of trunking - to pass all vlan traffic between the switches using only one port.

on switch 2 when i do sh run int gi0/1 &nbsp;i get<br />
<br />
switchport trunk encapsulation dot1q<br />
switchport mode trunk<br />
<br />
when i do sh int brief<br />
<br />
i see gi0/1 down/down<br />
i did no shut but no luck<br />
<br />
on switch 1<br />
<br />
switchport trunk encapsulation dot1q<br />
switchport mode trunk<br />
switchport trunk native vlan1<br />
<br />
<br />
so i cannot of course ping between the two switches...<br />
<br />
Any ideas ?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
