If you want to allow a low-priviledged user on a Cisco router or a Switch to view the Startup Config then this can be done in Routers and Switches running Cisco IOS.
This infact is a simple 2 step procedure as follows:

I dont think we need an introduction to the most widely used Remote console utility, PUTTY. Putty support SSH, Telnet, RLogin & RAW connections.
If you telnet or SSH to your Cisco IOS routers or switches or Juniper Firewalls and ofcourse anything that support CLI and SSH or Telnet then one of the things you would prefer to do is to take a backup of the config (Running or Startup) or even capture session text including logs tech information etc. We discussed here about using Hypereterminal to capture text and hence backup and restore config on Cisco IOS Routers and Switches.
When troubleshooting a problem with Access Control lists, one of the things you would want to do is to clear the counters on the ACL matches.
In Cisco IOS, you can clear the ACL Matches counters as follows:
Another beginner tip that can be useful!
When you work on the Cisco Router or Catalyst Switch console, it would be annoying to have the console or terminal (telnet/ssh) logs to pop in between your commands. This can be even more irritating when it is busy switch or a router spitting messages continuously.
With Spanning Tree Protocol, messages from a connected device always takes the least cost path to the Root Bridge. The least cost path also called as Link Cost or Port cost is the lowest cost path of the one or more paths available from the device to the root bridge. Each link type has its own default costs which is used by the Spanning Tree Protocol (STP) to calculate the least cost path.
In Cisco Catalyst switches, each switchport can be set to different VLAN Membership modes using the "switchport mode" command. This sets the port unconditionally.
The different modes include
With Cisco IOS version 11.2, Cisco introduced the Named ACLs. Named ACLs are Standard or Extended ACLs which are give names instead of a ACL number. Technically, other than giving a name to the ACL there isn't any other difference when it comes to the functionality as in Standard or Extended ACL.
