Cisco Webex Bandwidth Requirements

Cisco Webex Bandwidth Requirements – Network QoS Internet & Data Use

Cloud-based collaboration tools are one of the best options for increased productivity. The suite for Webex comprises Webex Meetings, Webex Teams, and Webex Devices. All these services were rebranded in April 2018 to form the Cisco Online Collaboration Portfolio. What are the Network and bandwidth requirements do these services need? We will find the details in finer detail. Let’s get started with the Cisco Webex Bandwidth Requirements in the following paragraphs.

Webex Products – An Overview

The Cisco Webex products come with core collaboration functionalities. The services include video meetings, team messaging and file sharing requirements. No matter whether you are looking for unified communication needs towards the small group collaborations and enterprise level collaborations, the services offered are quite excellent in its own right.

The service integrates well with Microsoft Teams and Slack. The Cisco Webex Platform is part of a wide range of facilities spread across multiple collaboration tools. The high end and seamless integration with all the services would make it an excellent option in every right.

Now that we are aware of what Cisco Webex offers you let us check out the network requirements you may need to have for each of the Webex components.

Cisco Webex Bandwidth Requirements:

Webex makes use of the following ports for communication whether inbound or outbound –

Protocol  Port Numbers Access Type
TCP 80 or 443 Outbound – Webex Client Access Port
TCP/UDP 53 Outbound – DNS
ODP 9000 Outbound – Webex Client Media
TCP/UDP OS Specific Inbound – Return Traffic from Webex

The ports for Video Collaboration include the following –

Protocol  Port Numbers Access Type
TCP /UDP 5060 – 5070 Outbound – SIP signaling
TCP 5060, 5061 and 5065 Inbound – SIP signaling
TCP /UDP 1719, 1720, 15000 to 19999 Inbound and outbound – H.323 LS
TCP/UDP Ephemeral Ports Inbound and outbound – media ports

You would need to whitelist the following domains for an uninterrupted functionality –

  • *.localytics.com
  • *.rackcdn.com
  • *.clouddrive.com
  • *.crashlytics.com
  • *js-agent.newrelic.com
  • *bam.nr-data.net
  • *.wbx2.com

The Webex hosted services are typically posted through AS13445. All the traffic from AS13445 needs to be allowed.

Total Per Hour 316 MB

The Concluding Thoughts

Well, those are a few network and bandwidth requirements you would need to work effortlessly with Webex systems. However, Webex is optimized to reduce the amount of data transmitted over the network. The Webex client will be transmitting the data only when the data is requested. For instance, when you are attending a meeting where the content is almost static most of the time, and Webex will not transmit any data. This will help keep the traffic to a minimum. Whenever there is an activity like loading a presentation, sharing an application or any other similar action – the data transfer will on only for a few seconds and only those parts of the screen will change which depends upon the exact changes.

Please note that we have not outlined all the network and bandwidth requirements while compiling this information. We have only focussed on the essentials elements alone. For more information, you may get in touch with the official Webex support.
