Hi, I am facing an strange problem. I am using cisco 2621XM router.
Router fast ethernet 0/0 is able to ping its ip itself but not ping LAN network users ip on the same subnet & vise-versa. Port status is showing up when network cable is plugged and down when cable is unplugged & also port is showing admin down when i shutting the port and showing up after no shut fa0/0 port.
1- I have connected my pc dirctly to router fa0/0 & erased all the configuration(only fa0/0 confiugred). ip given to pc and fa0/0 on the same subnet. but again not able to ping from router to PC and vise-versa.
2- Then I have connected my pc dirctly to router fa0/1 & erased all the configuration(only fa0/1 confiugred). ip given to pc and fa0/1 on the same subnet. Now i am able to ping from router to PC and vise-versa.
I also checked above two steps with latest IOS release but not successed.
Please help me out to identify exact cause and its solution.
Thanks in advance.......JEET
