Hi how can i found out which all ports are down in 48 port 2960 switch , which all ports are down from how long. thourgh LMS ( CISCO WORKS) and also through command line.
From command line, you can see if this info is in the logs:
You could also check your syslog server for this type of info, though that could be a pain for something like this.
In Ciscoworks, there are many ways to see which ports are down, but for the sake of killing two birds with one stone, look in the CiscoView module and click 'Chassis View'. Then use the expandable device tree or the search box to locate the device in question. Once you've located it, select it. Once the chassis is viewable, you can see which ports are down easily by the port color (green is up, orange is down, etc). Right click the interface that you want info about and click 'Configure'. In the popup window you should see "Last Change:" this is the last time the interface state changed, which should tell you when the interface went down last.
Edit: I want to add that if you bring up the interface before checking Ciscoworks, the "Last Change:" info would reflect when the interface came back up, hence the term "Last Change:".

You could do a show interface and look at the "last input , output" line:
