Reload will reboot the router without losing changes. &nbsp;Make sure that the running config is saved to NVRAM: copy run start

last week it was discovered that the port our backup appliance was plugged into was set for 100MB instead of 1GB. Common sense told us to turn it up, and everything was still pinging. I just noticed though that backups are no timing quie often, even though I can still ping th device. I am not too experianced at switches and need to commands to very port 1 is indeed set for 1GB and the command to bring it back to 100MB. Once backups are stable I will start to troubleshoot the issue. I am logged in with putty but confused how to verify and change. I cannot reach my co workers. All advice welcome

need to change speed of port 1 on cisco 3750 switch from 1GB back to 100MG

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.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

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.
