altSwTcpHoldDown

Module: CHEETAH-TRAP-MIB

OID (symbolic): CHEETAH-TRAP-MIB::altSwTcpHoldDown

OID (numeric): 1.3.6.1.4.1.1872.2.5.7.0.21

Node type: NOTIFICATION-TYPE

Description: A altSwTcpHoldDown trap signifies that new TCP connection requests from a particular client will be blocked for a pre-determined amount of time since the rate of new TCP connections from that client has reached a pre-determined threshold. The fltCurCfgSrcIp is the client source IP address for which new TCP connection requests will be blocked. The altSwTrapRate specifies the amount of time in minutes that the particular client will be blocked.

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> '' CHEETAH-TRAP-MIB::altSwTcpHoldDown
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.1872.2.5.7.0.21

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:

zoo11-linux.zoo [UDP: [192.168.30.111]:63394->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (423267746) 48 days, 23:44:37.46
