SNMP for ACE Failover.

[fariha zain]

Hi Experts,

Could someone please let me know the SNMP settings for my ACE failover.

Query:-

When my active 4710 ACE load balancer fails for any reason(due to s/w or h/w)  and the second 4710 ACE load balancer  take over (becoming active), will there be a SNMP alarm send from the ACE?

If so, which SNMP alarm will that be and which SNMP settings need to be applied for this?

Thanks in advance. Appriciate your comment on this.

Regards

Fari

Hello Fariha-

There is a MIB you can poll to get the current FT stats:

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.4.1.9.9.254.1.10.1.1#oidContent

As well, you can set "snmp-server enable traps syslog" with "logging enable" and "logging history 5" which will send all syslog messages (including ft failover messaging) as a trap to your snmp server.

Hi Christopher,

I configured the SNMP but nothing is been seen on SYSLOG Server. But I am able to ping the syslog server from ACE as it is in the same subnet.

But the messeges are not getting recored to the syslog server. I reloaded the ACE and saw OID getting generated for link up/dow and restart but nothing been recorded on the syslog server.

Is this a bug?

Generating configuration....

Logging part config:

logging trap 3

logging history 4

logging host 10.10.10.5 udp/514

SNMP part config:

snmp-server host 10.10.10.5 traps version 2c private

snmp-server trap-source vlan 32

snmp-server enable traps snmp coldstart

snmp-server enable traps virtual-context

snmp-server enable traps license

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

However, I don’t see the OIDs you mentioned.Alsothere is no incoming syslog message from any of the ACE load balancer IP addresses shown.

Anyhelp would be appriciated. Thanks in advance.

Regards,

Fari

Fari-

  configure "logging enable" on ACE - it should look like this:

logging enable

logging trap 3

logging history 4

logging host 10.10.10.5 udp/514
