I am getting the error while taking ssh of the router 1941. And i can able to access all other cisco switches routers thru ssh. But only 1941 router, i am facing the issue in daily 4-5 time. after 5-6 hrs it automatically comes up.
changed the cable. Checked the CPU utilization is normal - 5%.
Configured active standby mode and this router is in standby mode. there is less cpu utilization.
only SSH connection says "Network error : connection timed out .." The issue occurs at every day and after some time automatically SSH works fine. There is no specific time. It occurs randomly, no fixed time.
T Steps,
Reconfigured the SSH connection with 1024 key.
Verified the ACL rules.
SSH Config ;
ip access-list standard TELNET-ACCESS
permit 172.17.102.0 0.0.0.255
permit 172.17.103.0 0.0.0.255 --------> This Subnet,i couldn't access the SSH some times.
permit 172.21.102.0 0.0.0.255
permit 172.21.103.0 0.0.0.255
