Most routers and switches by Cisco have default passwords of admin or cisco, and default IP addresses of 192.168.1.1 or 192.168.1.254. However, some differ as shown in the table below.

Change the default login data once you're in to make your router more secure.

If you don't see your Cisco device or the default data below doesn't work, see below the table for more help, including what to do.

[1] The Cisco SFE1000P switch's default IP address is assigned via DHCP, meaning that it's different depending on the network that it's installed on. To determine the IP address for your SFE1000P, log in to the router or DHCP server that assigned the dynamic IP and look for it in the list of attached devices.

[2] The Cisco Valet M10 & Valet M20 routers are supported by Linksys. Cisco owned Linksys from 2003 through 2013 and branded the Valet routers with the Cisco name and logo. See our Cisco Valet M10 & Valet Plus M20 default password and support info page for more details.

Next Steps If the Cisco Default Login or IP Above Doesn't Work

If the default username or password doesn't work, it means that it's been changed.

Unlike residential routers, the Cisco business and enterprise-class routers and switches have specific password recovery features, meaning that a full factory reset (the typical reset-a-password process) isn't required.

If you can't locate the password recovery steps for your device, Cisco Support has a PDF manual for every device, which includes help in this area, too.

Most network devices operate with the default IP address they come with but routers, and especially switches, in business and enterprise environments, are often changed when installed. Learn how to identify network hardware IP addresses on a local network if the default IP isn't working.
