How many Ports are in the Router?
All the other ports are working fine ?
If you have more then One Ports in your router , Why cont you change the connecting to an another port. If we do this , we will know whether the particular Port is working properly or not.
And then see the ports properties,
There will be Two type of problems ,
1 . Hard were Problems.
2. Soft were problems.
1.
May in the router , there will an option to reset. Just do a reset and then connect.Whether it is working properly or not.
And in the Port , Some interface which are in micro might be broken.
2.
Hope you know about the MIB. Just query to the MIB for the particular Port, and Get the port's information. If that Port is fine , the Information will be returned successfully. Otherwise they give some error code about that port's problem , just make a search with that error code in the Google. They will tell what is the problem for that property of the Port.
An another option , just load that MIB to any simulator(ex: SNMP agent simulator) . Now it will be easy for you to query the information of the Particular property.
Hope this will be helpful.
