Hi all,

I have been working with the AOS-CX role for a while and decided to see if I could improve the speed of administration of  VLANs with aoscx_vlan.  Currently I am have them all in a vars file like:

vlans:
  ....
  - {vlanid: '399', vlanname: 'vlan4000', vlanstate: 'delete'}
  - {vlanid: '4000', vlanname: 'vlan4000', vlanadminstate: 'up', vlanstate: 'create'}

Hi Don,

I think, it is better to ask directly on Ansible AOS CX github

What latency do you have to the switch ? (on the same LAN ?)
do you have look log to see what it is make ?

Hi all,

I have been working with the AOS-CX role for a while and decided to see if I could improve the speed of administration of  VLANs with aoscx_vlan.  Currently I am have them all in a vars file like:

vlans:

  - {vlanid: '4', vlanname: 'vlan0004', vlanadminstate: 'up', vlanstate: 'create'}

  - {vlanid: '8', vlanname: 'vlan0008', vlanadminstate: 'up', vlanstate: 'create'}

  ....
  - {vlanid: '399', vlanname: 'vlan4000', vlanstate: 'delete'}
  - {vlanid: '4000', vlanname: 'vlan4000', vlanadminstate: 'up', vlanstate: 'create'}

and the task is:

  - name: Create VLANs

    aoscx_vlan:

      vlan_id: "{{ item.vlanid }}"

      name: "{{ item.vlanname }}"

      admin_state: "{{ item.vlanadminstate | default(omit)  }}"

      state: "{{ item.vlanstate }}"

    loop: "{{ vlans | flatten (levels=1) }}"

My vars file has about 80 vlans defined and takes about 50 seconds per switch to run. Not terrible, but you can see where this will be a bottleneck once getting past a handful of switches.

I did a bit of research and found a few Ansible config changes to try, it saved about 1 second off the time. Found other suggestions that were module specific which the aoscx_vlan module does not support, aggregate (eos module), src + jinja template (nxos module). 


Any suggestions to improve this workflow?

Typical latency is ~0.4ms.  For a log, are you talking about a -vvvv output or a log from the switch?

Yes,

I think there is a also some timer on the switch when you add a vlan...
(and i think it is not yet possible to add multiple vlan on the same time/POST API request)

for (Iterator<String> i = someIterable.iterator(); i.hasNext();) {
String item = i.next();
System.out.println(item);
}
Note that if you need to use i.remove(); in your loop, or access the actual iterator in some way, you cannot use the for ( : ) idiom, since the actual iterator is merely inferred.

As was noted by Denis Bueno, this code works for any object that implements the Iterable interface.
