Network configuration
All Ethernet ports on the device support the tunnel service. Assign Twenty-FiveGigE 1/0/1 through
Twenty-FiveGigE 1/0/3 to a service loopback group to loop GRE packets sent out by the device back
to the device.
Procedure
# Create service loopback group 1, and specify its service type as tunnel.
<Sysname> system-view
[Sysname] service-loopback group 1 type tunnel
# Assign Twenty-FiveGigE1/0/1 through Twenty-FiveGigE1/0/3 to service loopback group 1.
[Sysname] interface twenty-fivegige 1/0/1
[Sysname-Twenty-FiveGigE1/0/1] port service-loopback group 1
All configurations on the interface will be lost. Continue?[Y/N]:y
After this command is executed, the speed will be reset to the default value on
Twenty-FiveGigE1/0/1 to Twenty-FiveGigE1/0/4, which belong to the same port group.
Continue? [Y/N]:y
[Sysname-Twenty-FiveGigE1/0/1] quit
