1.4.6 Enabling the quick-ping Function
Now, the S9500 Switch responds slowly to a Ping request, because all processing
actions of the Ping command (including an ICMP Request) are sent to the SRPU. As a
result, it causes great load to the system and even affects system running. To solve this
problem, the Switch provides a quick-ping enable command so that all processing
actions are implemented on the interface card. It relieves the load on the SRPU, and
speeds up the processing of the Ping command.
Follow these steps to enable the quick-ping function:
Enter system view
Enable the quick-ping
function
Note:
MPLS packets, Ping packets received on an MPLS-enabled interface and large Ping
packets (to be fragmented) are still sent to the SRPU of the device for processing.
