Hi !


I tried to enable Traps on the ACE Module - but in case of Real-Server Failure nothing is sent out...


I did the following:


snmp-server host xxx.xxx.xxx.xxx traps version 2c xxxxxxxx


snmp-server trap-source vlan xxx


snmp-server enable traps slb vserver

snmp-server enable traps slb real

snmp-server enable traps syslog

snmp-server enable traps snmp authentication

snmp-server enable traps snmp linkup

snmp-server enable traps snmp linkdown


interface vlan 210

description Mgmt-Interface

ip address xxxxx

peer ip address xxxxx

access-group input PERMIT_ALL

access-group output PERMIT_ALL

service-policy input mgmtaccess

no shutdown




Could you please let me know if I did anything wrong ?


thx

Hans

HI Hans,


When you specify the slb keyword, specify the real or vserver keyword to enable server load-balancing notifications. This selection generates a notification if:


The real server changes state (up or down) due to occurrences such as user intervention, ARP failure, and probe failure.




Also ,I think you have not configured SNMP communities (SNMP uses software entities called managers and agents to manage network devices)


Kindly refer the following link for getting full configuration in this regard:

Is there any real server failure occur and no trap generated plx tell.

Hi !


that`s what I did:


snmp-server enable traps slb vserver

snmp-server enable traps slb real


The real server is down - but no SNMP Trap is sent.


f.e.: rserver: OSN03_IN1

xxx.xxx.xxx.xxx:0 8 ARP_FAILED 0 937 85


unfortunately I do not see any trap on the Mgmt-VLAN.


thx

Hans
