chasIpAddrToPing
Module: CHASSIS-MIB
OID (symbolic): CHASSIS-MIB::chasIpAddrToPing
OID (numeric): 1.3.6.1.4.1.800.2.1.1.9
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: The IP address to which a ping should be issued. A Network Management Station can use this to issue directed broadcast pings so as to augment the IP ARP table. The ARP table is useful in discovering the IP network topology.
What is chasIpAddrToPing?
Setting this object tells the chassis to issue a directed-broadcast ping to the specified IP address, a mechanism the description says an NMS can use to populate the device's IP ARP table and thereby help discover the surrounding IP network topology. An admin exploring an unfamiliar subnet attached to this chassis would SET this object to a broadcast address on that subnet to force the chassis to learn the MAC-to-IP mappings of hosts there, rather than waiting for organic traffic to populate the ARP cache. Setting chasIpAddrToPing to 10.10.5.255, a subnet broadcast address, would prompt the chassis to ping that address and populate its ARP table with the responding hosts on that /24.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.800.2.1.1.9 snmpwalk -v2c -c public <target> CHASSIS-MIB::chasIpAddrToPing
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.800.2.1.1.9.1 snmpget -v2c -c public <target> CHASSIS-MIB::chasIpAddrToPing.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.800.2.1.1.9.1 a <value>
