<Sysname> debugging tunnel event
*Jul 17 09:16:07:930 2008 Sysname TUNNEL/7/debug:
Tunnel1 can't come up because:
// The link state of Tunnel1 cannot be up, and the reason might be the following:
*Jul 17 09:16:07:930 2008 Sysname TUNNEL/7/debug:
Tunnel source is null.
// The link state of Tunnel1 was down because the source IP address was not configured.
*Jul 17 09:16:07:935 2008 Sysname TUNNEL/7/debug:
Tunnel destination is null.
// The link state of Tunnel1 was down because the destination address was not configured.
# Enable tunnel packet debugging on the local device. The output in this example was created when the
following conditions exist:
•
Tunnel interfaces have been created on two devices.
•
For some switches, packet decapsulation is implemented through chips. After being received by the
local device, the tunnel packets are decapsulated, and then sent to the tunnel interface for
processing.
