One of the core switches lost its layer 3 routing capability. The switch was working fine until the afternoon of 2nd of October when it stopped responding to pings. When connected through the console the switch is unable to ping any of the local or remote subnets/hosts. It doesn?t appear that any of the layer 2 switching capability has been affected by this issue as the hosts connected directly to this switch do not seem to be affected. Fortunately, this switch is not used as the default gateway for any networks, not VLAN interfaces are configured on it for this purpose, but I am concerned that this issue may be part of a greater issue on this device that may result in the chassis failing at some point in the near future.
Please could any one help me to find the solution to this issue.
