Parameter
number: Maximum number of hops that an NQA ICMP test packet can pass in the
network, in the range of 1 to 255. This parameter equals to the "-i" parameter in
the ping command of the Windows operation system.
Description
Use the ttl command to configure the maximum number of hops that an NQA
ICMP test packet can pass in the network, that is, the "life time" of the NQA
packet.
Use the undo ttl command to restore the maximum number of hops that a NQA
ICMP test packet can pass in the network to the default value.
By default, the maximum number of hops that an NQA ICMP test packet can pass
in the network is 20.
Example
# Configure the maximum number of hops that an NQA test packet can pass in
the network to 16.
<SW8800>system-view
System View: return to User View with Ctrl+Z.
