Output Characters from PING
This table is taken from the following Cisco article:
Understanding PING and Traceroute Commands
Understanding PING and Traceroute Commands
The table below lists the possible output characters from the ping facility:
| Character | Description |
|---|---|
| ! | Each exclamation point indicates receipt of a reply. |
| . | Each period indicates the network server timed out while waiting for a reply. |
| U | A destination unreachable error PDU was received. |
| Q | Source quench (destination too busy). |
| M | Could not fragment. |
| ? | Unknown packet type. |
| & | Packet lifetime exceeded. |
And I just want to log this here for quick reference. Thanks
