Basic Requirements of Operational Scripts
For operational (op) scripts, the context is a required argument because a context is transmitted to the script, when the script is run from troubleshooting operation. The format of the argument to be pushed to the script is as follows:
var $arguments = {
<argument> {
<name> "CONTEXT";
<description> "The CONTEXT.";
}
}
var $CONTEXT;
The context has parameters based on the service type, which needs to be parsed to use the parameters.
The following is an example of an E-Line LDP service context:
Context: /device[name=”deviceName”]/configuration/protocols/l2circuit/neighbor[name=”neighbor IP”]/interface[name=”interfaceName.unitID”]
The code in op script to parse the context is as follows:
var $tempContext = str:replace(str:replace($CONTEXT, "/device[name=\"", ""), "\"]/configuration/protocols/l2circuit/neighbor[name=\"", "|"); var $finalContext = str:replace(str:replace($tempContext, "\"]/interface[name=\"", "|"), "\"]", ""); var $variables = jcs:split( "\\|", $finalContext ); var $deviceName = $variables[1]; var $neighborIp = $variables[2]; var $interfaceName = $variables[3];
The following is an example of an E-Line BGP service context:
Context: /device[name=”device name”]/configuration/routing-instances/instance[name=”Service name” and instance-type=”l2vpn”]/bgp/interface[name=”interfaceName.unitID”]
The code in op script to parse the context is as follows:
var $tempContext1 = str:replace(str:replace($CONTEXT, "/device[name=\"", ""), "\"]/configuration/routing-instances/instance[name=\"", "|"); var $tempContext2 = str:replace($tempContext1, "\" and instance-type=\"l2vpn\"]", ""); var $finalContext = str:replace(str:replace($tempContext2, "/bgp/interface[name=\"", "|"), "\"]", ""); var $variables = jcs:split( "\\|", $finalContext ); var $deviceName = $variables[1]; var $instanceName = $variables[2]; var $interfaceName = $variables[3];
The following is an example of an E-Line E-LAN service context:
Context: /device[name=”device name”]/configuration/routing-instances/instance[name=”Service name” and instance-type=”vpls”]/vpls/interface[name=”interfaceName.unitID”]
The code in op script to parse the context is as follows:
var $tempContext1 = str:replace(str:replace($CONTEXT, "/device[name=\"", ""), "\"]/configuration/routing-instances/instance[name=\"", "|"); var $tempContext2 = str:replace($tempContext1, "\" and instance-type=\"vpls\"]", ""); var $finalContext = str:replace(str:replace($tempContext2, "/vpls/interface[name=\"", "|"), "\"]", ""); var $variables = jcs:split( "\\|", $finalContext ); var $deviceName = $variables[1]; var $instanceName = $variables[2]; var $interfaceName = $variables[3];
The following is an example of an E-Line IP service context:
Context: /device[name=”device name”]/configuration/routing-instances/instance[name=”Service name” and instance-type=”vrf”]/vrf/interface[name=”interfaceName.unitID”]
The code in op script to parse the context:
var $tempContext1 = str:replace(str:replace($CONTEXT, "/device[name=\"", ""), "\"]/configuration/routing-instances/instance[name=\"", "|"); var $tempContext2 = str:replace($tempContext1, "\" and instance-type=\"vrf\"]", ""); var $finalContext = str:replace(str:replace($tempContext2, "/vrf/interface[name=\"", "|"), "\"]", ""); var $variables = jcs:split( "\\|", $finalContext ); var $deviceName = $variables[1]; var $instanceName = $variables[2]; var $interfaceName = $variables[3];
Predefined Scripts for Troubleshooting
