isisVersionSkew
Module: ISIS-MIB
OID (symbolic): ISIS-MIB::isisVersionSkew
OID (numeric): 1.3.6.1.2.1.138.0.11
Node type: NOTIFICATION-TYPE
Description:
A notification sent when we receive a Hello PDU from an IS running a different version of the protocol. This notification includes the header of the packet, which may help a network manager identify the source of the confusion.
The agent must throttle the generation of consecutive isisVersionSkew notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time.
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> '' ISIS-MIB::isisVersionSkew snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.138.0.11
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
