Description: A rcMstpNewCistRegionalRoottrap signifies that the SNMPv2 entity, acting in an agent role, has detected the Multiple Spanning Tree Protocol has declared the device to be the new regional root of the common internal spanning tree.

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::rcnMstpNewCistRegionalRoot
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2272.1.21.0.119

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
