icmpEchoReq
Module: HP-UNIX
OID (symbolic): HP-UNIX::icmpEchoReq
OID (numeric): 1.3.6.1.4.1.11.2.7.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The number of milliseconds it takes for an ICMP echo request to respond. IcmpEchoReq is -1 if there is an internal error, -2 if the echo request timed out, -3 if the echo reply is not the correct reply, -4 if the packet size is too large, and -5 if the timeout is invalid.
To request the ICMP response time for IP address a1.a2.a3.a4 with a timeout of t and a packet size of s, send a request for icmpEchoReq.s.t.a1.a2.a3.a4.
For example, suppose one wanted to find out the number of milliseconds it took to ping 15.2.112.113, with time out of 8 seconds, and packet size of 75. Accordingly, icmpEchoReq.75.8.15.2.112.113 would identify the number of milliseconds.
This MIB object is there only to provide for backward compatibility. A new MIB object is provided which does not violate the SNMP standards too, 'icmp.icmpEchoReqTable.icmpEchoReqEntry.icmpEchoReqTime'. This new MIB object is recommended to be used to achieve the same funtionality as provided by this (icmp.icmpEchoReq) MIB object.
What is icmpEchoReq?
Triggers an ICMP echo (ping) to a target IP by encoding the packet size, timeout, and address into the OID itself (e.g. icmpEchoReq.75.8.15.2.112.113 pings 15.2.112.113 with an 8-second timeout and 75-byte packets), returning the round-trip time in milliseconds or a negative error code (-1 internal error, -2 timeout, -3 bad reply, -4 packet too large, -5 invalid timeout). The description explicitly says this legacy object is kept only for backward compatibility and that icmpEchoReqTime (the indexed table version) should be used instead.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11.2.7.1 snmpwalk -v2c -c public <target> HP-UNIX::icmpEchoReq
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.11.2.7.1.1 snmpget -v2c -c public <target> HP-UNIX::icmpEchoReq.1
