Displaying GRE tunnel information
To display information about all GRE tunnels configured on a device, enter the following command.
Syntax: show gre tunnel-number
The tunnel-number option allows you to limit the display to information about a specified tunnel.
Displaying GRE and manual IPv6 tunnel statistics
This section contains examples of the following show commands for GRE tunnel and manual IPv6
tunnel statistics:
• show ip-tunnels
• show ip-tunnel tunnel ID
• show statistics brief tunnel tunnel ID
• show statistics tunnel tunnel ID
• show interface tunnel tunnel ID
To see a list of the configured tunnels with some details of each tunnel, use the show ip-tunnels
command as the following example illustrates. This example shows that one tunnel exists; it has IP
tunnel statistics collection enabled; and neither GRE nor IPv6 session enforce are enabled.
Syntax: show ip tunnel number
Syntax: show ip tunnels
The output of this command contains the following type of information:
passive resets The number of TCP connections this device reset because the device at the other
end of the connection sent a TCP RESET message.
input errors This information is used by Brocade customer support.
in segments The number of TCP segments received by the device.
out segments The number of TCP segments sent by the device.
retransmission The number of segments that this device retransmitted because the retransmission
timer for the segment had expired before the device at the other end of the
connection had acknowledged receipt of the segment.
