Default level
2: System level
Parameters
value: Maximum number of hops a probe packet traverses in the network, which ranges from 1 to 255.
Description
Use ttl to configure the maximum number of hops a probe packet traverses in the network.
Use undo ttl to restore the default.
By default, the maximum number of hops that a probe packet can traverse in a network is 20.
After you configure the route-option bypass-route command, the maximum number of hops a probe
packet traverses in the network is 1, and the ttl command does not take effect.
Examples
# Configure the maximum number of hops that a probe packet can traverse in a network as 16.
