Configuring the SLA Mon Agent
Configure the SLA Mon agent to communicate with an SLA Mon with SLA Mon technology to perform Quality of Service (QoS) tests of the network.
Before you begin
-
To use the SLA Mon agent, you must have an Avaya Diagnostic Server with SLA Mon technology in your network.
About this task
To configure the SLA Mon agent, you must assign an IP address and enable it. Remaining agent parameters are optional and you can operate the agent using the default values.
Note
-
If you want to change SLA Mon parameters, you must first disable SLA Mon.
If you are configuring SLA Mon at the switch side for the first time, make sure you configure the SLA Mon agent address under an IP address for a VLAN or brouter, and you must remove the SLA Mon address before you can remove the IP address for the VLAN or brouter. To remove the SLA Mon address, first use the command no slamon oper-mode enable, followed by slamon agent ip address 0.0.0.0.
Procedure
-
Configure the SLA Mon agent IP address:
Note
The SLA Mon Agent uses its own reserved Host IP address, reachable via the Switch VLAN IP interface of the same IP subnet.
slamon agent ip address {A.B.C.D} [vrf WORD<1-16>]
Example
-
Configure the SLA Mon agent IP address. Configure the agent so that it only accepts registration packets from a specific server communicating on a specific port. Finally, enable the SLA Mon agent, and then verify the configuration.

What to do next
If you have configured SLA Mon, but the agent does not function as expected, use the show khi performance pthread [{slot[-slot][,...]}] command to verify that the slamon task is running.
If the SLA Mon agent is not running, use the commands no slamon oper-mode enable and slamon oper-mode enable to start the agent.
If the agent task is running, perform typical troubleshooting steps to verify agent accessibility:
-
Verify IP address assignment and port use.
-
Ping the server IP address.
-
Verify the server configuration.
-
Use the trace level 192 <0-4> command to observe the status of the SLA Mon software module.
Variable definitions
Use the data in the following table to use the slamon command.
|
Variable |
Value |
|---|---|
|
agent-comm-port <0–65535> |
Configures the port used for RTP and NTR testing in agent-to-agent communication. The default port is 50012. If you configure this value to zero (0), the default port is used. |
|
agent ip address {A.B.C.D} |
Configures the SLA Mon agent IP address. You must configure the IP address before the agent can process received discovery packets from the server. The agent ip address is a mandatory parameter. The default value is 0.0.0.0. |
|
agent port <0–65535> |
Configures the UDP port for agent-server communication. The SLA Mon agent receives discovery packets on this port. The default is port 50011. The server must use the same port. |
|
install-cert-file |
Installs an SSL certificate. WORD<0-128> specifies the file name and path of the certificate to install. If you install a certificate on the SLA Mon agent, you must ensure a matching configuration on the server. |
|
oper-mode enable |
Enables the SLA Mon agent. The default is disabled. If you disable the agent, it does not respond to discovery packets from a server. If you disable the agent because of resource concerns, consider changing the server configuration instead, to alter the test frequency or duration, or the number of targets. |
|
server ip address {A.B.C.D} [{A.B.C.D}] |
Restricts the SLA Mon agent to use the server at this IP address only. The default is 0.0.0.0, which means the agent can register with any server. You can specify a secondary server as well. |
|
server port <0–65535> |
Restricts the SLA Mon agent to use this registration port only. The default is 0, which means the agent disregards the source port information in server traffic. The server must use the same port. |
|
vrf WORD<1-16> |
Specifies the name of a VRF. |
