rcnInsufficientMemory
Module: RAPID-CITY
OID (symbolic): RAPID-CITY::rcnInsufficientMemory
OID (numeric): 1.3.6.1.4.1.2272.1.21.0.36
Node type: NOTIFICATION-TYPE
Description:
A rcInsufficientMemory trap indicates insufficient memory on CPU blade for proper operation. Recommended memory = 256 MB available through Nortel Networks upgrade kit
What is rcnInsufficientMemory?
This is an alert notification that fires when the network device's main CPU processor runs low on available memory, typically below 256 MB. It signals a serious problem that will degrade the device's ability to route traffic or process network commands normally. An operator receiving this alert would immediately check memory usage and likely reboot the device or install additional RAM to restore stable operation.
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> '' RAPID-CITY::rcnInsufficientMemory snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2272.1.21.0.36
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
