Hi All,

I have a IP SLA and track configured in ASA. I want to get a SNMP trap or a syslog alert when these go down.

Hi Cisco Freak,

This is the Syslog that triggers when there is a change in routing as configured by the tracking and SLA:

622001

Error Message %PIX|ASA-6-622001: string tracked route network mask address, distance number, table string, on interface interface-name

e.g. Sep 05 2013 17:18:10: ASA-6-622001 Removing tracked route 1.2.3.3 255.255.255.255 72.163.4.1, distance 100, table Default-IP-Routing-Table, on interface outside

Explanation
A tracked route has been added to or removed from a routing table, which means that the state of the tracked object has changed from up or down.

string-"Adding" or "Removing."
network-The network address.
mask-The network mask.
address-The gateway address.
number-The route administrative distance.
string-The routing table name.
interface-name-The interface name as specified by the nameif command.

Recommended Action None.
This is an informational message that indicates a change in routing and a likely change in forwarding paths, as configured by the tracking and SLA commands.


Here is the configuration in order to send an alert via e-mail directly to your account:

logging list test message 622001
logging mail test
logging from-address ciscosecurityappliance@example.com
logging recipient-address admin@example.com level errors
logging message 622001 level alerts
smtp-server <ip address>

Hi Dinesh,

There is no routing change happening when the track/IP SLA goes down.

Can you help me explain how are you using SLA monitor in the configuration. Is it nor associated with any tracking ? What is the purpose for this SLA ?

We have an intermittent IPSEC vpn flap issue. I want to confirm if the reachability to remote site public IP is the root cause for VPN flap.

So I have configured a IP SLA to ping other end public IP every 2 seconds. Whenever there is a lose if connectivity, I want to get a syslog/SNMP trap.

Any help would be appreciated.

You might want to run the following debugs and check the specific ID for the logging message to be sent to the syslog server:

debug sla monitor trace
debug sla monitor error
