In this post, I will show you how to configure up your Pulse Secure VPN client to not tunnel Cisco Webex traffic over your VPN tunnel.

Due to COVID-19, there has been a rapid push to extreme levels of remote work. Many networks, including ours, are seeing traffic flows that significantly differ from anything we’ve ever seen before. For example: VPN Gateways fully utilized, Internet circuit utilization that is through the roof, and an unprecedented level of Cisco Webex usage. All of this has changed the network traffic flows and it has created a need to look at what is going on inside our network and look for ways to quickly optimize it for efficiency and best end-user experience.

About a year ago, we did an upgrade on our standalone Cisco Prime License Manager (PLM). After the upgrade, the option to schedule backups via the GUI was no longer there. Initially, I was told by a Cisco TAC Engineer that scheduled backups were not possible.

RTMT-IconI recently did a migration to move our CUCM nodes to be specified by FQDN hostname. We had been using non-FQDN hostnames, however, we wanted to migrate to using the FQDN hostname to line up with current best practices and in prep for piloting Mobile and Remote Access (MRA) on Expressway. In the process of putting together my implementation plan, I realized that we would likely lose any RTMT profiles we had saved which can be quite complicated and have a number of custom counters defined.

IPPhoneFew things in collaboration will get people more worked up than a user experience change, especially when a contact center is involved. (Protip: do NOT anger the contact center gods). Here is a little story about firmware release 9.4(2SR1.1) (or 9-4-2SR1-1S or 9.4(2)SR1 depending on where you see the version referenced) for the Cisco 7900 series IP Phones and how it has caused grief for not only us, but other customers as well.
