As part of UpKeep, our feature to keep NWG Manage customers' devices on the latest stable version, we reviewed the latest Cisco releases and recommend the upgrades detailed below.

Why Are You Sharing This Information?

Even if we're not managing Cisco switches for you, we want you to have the latest information to help keep your devices secure.

• What should I do if I have a Cisco switch that NWG manages?
  If you have a Cisco Switch(es) that we manage for you, we already know what hardware you have and what version you need to be on. We’ll handle the upgrade during an upcoming maintenance window (unless you are already running the recommended version). Zendesk notifications will be sent out once maintenance has been scheduled, including details about when implementation will take place. If your devices/locations require different days/times for maintenance to take place, you’ll receive separate tickets.
• What if I have a Cisco switch that NWG does not manage?
  If you have a Cisco switch(es) in your environment, we suggest you upgrade to the recommended version.
• What if I don't have any Cisco switches?
  If you don't have any Cisco switches, no action is needed.

Which Cisco Release Do You Recommend?

For Cisco SG250 switches: 2.5.9.55

• 2.5.9.55 is the latest stable, long-term support release for SG250 switches.

• This is the version recommended by Cisco. 

For other Cisco switch models:

• Currently, NWG is in line with Cisco's recommendations to upgrade to the latest release compatible with your specific model. These versions are all stable.
• The current recommendations focus on long-term support releases, not bleeding-edge versions, so for this round of UpKeep, we have no concerns about following the manufacturer’s suggestions.
• A detailed list is as follows (note: this list does not include all Cisco switch models. We only reviewed the models that we manage.):
