wsTrapNsmDhcpIPChanged

OID (symbolic): WS-TRAP-MIB::wsTrapNsmDhcpIPChanged

OID (numeric): 1.3.6.1.4.1.388.14.5.1.3.4

Node type: NOTIFICATION-TYPE

Description: Interface IP Address assigned by DHCP has changed.

Solution: If a different DHCP server assigned the IP address this time, disable the unwanted server and restart the blade.

Other Possibilities: Time may not be correctly set on the blade. If the current time on the blade is significantly off from the time on the DHCP server, the same DHCP server may assign a new IP address when the lease is renewed.

Severity: TP_SEV_NORM

Message: Interface: [str], New IP: [str]/[uint]

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' WS-TRAP-MIB::wsTrapNsmDhcpIPChanged
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.388.14.5.1.3.4

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:
