Configuration Examples

Use the following examples to configure various rules and comparison operators and operands for a Command Template.

Example 1

In this example, we need to verify Cisco CSR has sufficient memory. The IOS command show platform software vmemory info prints memory statistics, including the total system memory.

In the application:

1. Create a new Command Template.
2. Select a device name for testing.
3. Type show platform software vmemory info in the command field of Command #1.
4. Keep the default contains operator.
5. Click Test This Command.
6. The test results will display.

Example Test Results

Memory Upgrade Limits:
    Total System Memory:        3890 MB
    Memory From Upgrade Licenses:   0 MB
    Memory From Feature Licenses:   0 MB
Memory Available For Upgrade:
    Available System Memory:    0 MB
    Available Upgrade Licensed Memory:  0 MB
    Available Feature Licensed Memory:  0 MB
Current Memory Allocation:
    IOSD:   2354 MB (default) + 0 MB upgrade
    Data Plane: 1536 MB (default) + 0 MB upgrade

Top Comparison Operand

To build a regular expression to select data:

1. Select RegEx operator.
2. Type a regular expression to select the command's output data containing the first operand. The line containing "Total System Memory" includes the first operand, 3890 MB.
3. Type Total System Memory:\s+\d+ MB in the rule field.
4. Click Test This Command.
5. Verify a green check is displayed, indicating the rule matches.
6. If a red dash is displayed, check the regular expression for errors.

To build a capture group:

1. Change the command operator to #comparison.

2. Surround the regular expression rule with slash characters:

   /Total System Memory:\s+\d+ MB/
   

3. Add a capture group by placing a pair of parentheses around the part of our regular expression matching installed memory:

   /Total System Memory:\s+(\d+) MB/
   

To set the comparison operator:

1. Select >= comparison operator.

Bottom Comparison Operand

To define a comparison using a Bottom Operand:

1. Type 3000 in the compare with field.
2. Click Test This Command.
3. Verify a green check is displayed, indicating the rule matches.
4. If a red dash is displayed, check the top comparison operand regular expression for errors.

Example 2

This example extends the previous example; we need to verify Cisco CSR has sufficient memory. In the previous example, we compared installed memory to a static value. In this example, we compare installed memory to a variable.

Variable MEM-THRESH will be passed to the MOP command template.

Bottom Comparison Operand

• Type <!MEM-THRESH!> in the Compare with field.

Example 3

In this example, we have an EBGP adjacency configured with a maximum prefix of 10 prefixes. The adjacency is configured to log warning messages when the neighbor sends 80% or more of the maximum number of prefixes, and the adjacency is reset if the neighbor sends more than 10 prefixes. In this example, we verify the number of sent prefixes is not greater than the warning threshold.

The IOS command show ip bgp neighbor X.X.X.X prints the number of accepted prefixes, the maximum prefix limit, and the warning threshold.

1. In the application, create a new command template.

2. Select a device name for testing.

3. Type show ip bgp neighbor X.X.X.X in the command field for Command 1.

   • Replace X.X.X.X with a valid EBGP neighbor's router ID.

4. Keep the default contains operator.

5. Click Test This Command.

6. The test results will display.
