See Step 3 below about setting up a password for the Privileged EXEC mode. Note: The switch will not ask you for a password when entering into Privileged EXEC mode (i.e after typing “enable”) if it has the default factory configuration. You will get into privileged EXEC mode (“ Switch#”)
You will get the initial command prompt “ Switch>” Use a terminal emulation software such as PuTTY and connect to the console of the switch. I don’t like graphical GUI or web management at all, so I will show you command line configuration (CLI) which is much more powerful and actually forces the administrators to learn what they are doing on the device. In this article I will describe the basic steps needed to configure and setup a Cisco switch from scratch. Unlike other lower class switch vendors (which are plug-and-play), the Cisco switch needs some initial basic configuration in order to enable management, security and some other important features. Versatile, reliable, flexible and powerful, the Cisco switch product line (such as the 2960, 3560, 3650, 3850, 4500, 6500, 9400 series etc) offer unparalleled performance and features.Īlthough a Cisco switch is a much simpler network device compared with other devices (such as routers and firewalls for example), many people have difficulties to configure a Cisco Catalyst Switch. System poll interval is 8, never updated.In my opinion, the Cisco switches are the best in the market. Loopfilter state is 'FSET' (Drift set from file), drift is 0.000000000 s/s
Root dispersion is 3.25 msec, peer dispersion is 0.00 msec Ntp uptime is 22800 (1/100 of seconds), resolution is 5263 Nominal freq is 190.7348 Hz, actual freq is 190.7348 Hz, precision is 2**20
Translating "0.cz.".domain server (255.255.255.255)Ĭommand sh ntp status prints after reboot the following Clock is unsynchronized, stratum 16, no reference clock It prints over console follwoing message, stucks for aproximaltelly 10 seconds and then continues with initialization of interfaces, VLANS, SSH and so on. I think the cause is that switch tries to resolve "0.cz." using DNS in time when ports are disabled and no communication with DNS server can occur. In netflow collector I see that switch do not produce any NTP request to the NTP server and only way to force switch manually sync time is to run following commands again after each reboot manually. ntp server 0.cz.Īnd it works and sync time but after switch reload it does not sync time. I try to setup automatic syncing time on Cisco Catalyst 2960-CG-8TC-L switch using following command.
