Pinging Host Devices
Use the Ping Host task in Monitor mode to determine whether an MX Series host can be reached over the network from the device selected in the network tree. Entering a hostname or an address creates a periodic ping task that sends a series of Internet Control Message Protocol (ICMP) echo (ping) requests to the specified host. The output of the task displays in the Response Console.
The Ping from Device to a Host task is available only for ACX Series routers, M Series routers, MX Series routers, and PTX Series routers in your network.
- Select either IP or HostName in the Remote Host Details box.
- Type the IP address or hostname for the device that you want to reach.
- Click Ping to use the default settings and start the requests or select the plus (+) symbol to use the Advanced Search Criteria. The fields in Advanced Search Criteria are described in Table 1.
Table 1: Ping Host Advanced Search Criteria Field Descriptions
Indicates the number of ping requests to send. Valid values are 1 through 24.
Type of Service
Sets the type-of-service (ToS) field in the IP header of the ping packets. The range of values is 0 through 255. If the routing platform does not support ToS, the field is ignored.
Time To Live
Indicates the time-to-live hop count for the ping request packet. Valid values are 0 through 255.
Indicates the amount of time in seconds between ping requests. Valid values are 0 through 24; a 0 value sends the request immediately.
Indicates the size of the ping request packet in bytes. The routing platform adds 8 bytes of ICMP header to this size before sending the request packet.
Sends the ping requests on the interface you specify. Iif you do not specify this option, ping requests are sent on all interfaces.
Uses the source address that you specify in the ping request packet.
