Overview

Get certain number of ips within a prefix

Examples

def test_fun(duthosts, rand_one_dut_hostname, tbinfo):
    duthost = duthosts[rand_one_dut_hostname]

    mg_facts = duthost.get_extended_minigraph_facts(tbinfo)

    vlan_addr = mg_facts['minigraph_vlan_interfaces'][0]['addr']
    vlan_prefix = mg_facts['minigraph_vlan_interfaces'][0]['prefixlen']

    ips_in_range = duthost.get_ip_in_range(num=1, prefix="{}/{}".format(vlan_addr, vlan_prefix))

Arguments

  • num - Number of ips to be generated
    • Required: True
    • Type: Integer
  • prefix - required IP range in prefix format
    • Required: True
    • Type: String
  • exclude_ips - List of ips within the prefix that should be excluded from generation
    • Required: False
    • Type: List
      • Element-Type: String

Expected Output

Returns dictionary containing generated ips. The dictionary hierarchy is described below, with each indentation describing a sub-dictionary:

  • ansible_facts
    • generated_ips - list of generated ips

(u'ansible_facts', {u'generated_ips': [u'192.168.0.1/21', u'192.168.0.2/21']})
