Cisco 6807 VSS ISSU Upgrade

The Request:

I have a client with multiple 6807 VSS pairs that required an IOS upgrade. All of the pairs have a single SUP2-T in each chassis and were in the 15 code train. Although the ISSU process is very straight forward I wanted to put this quick process up as I had to search through multiple documents to gather all the pieces I needed to knock it out.

Cisco Unified Communications Manager & Unity Connection SFTP Emergency Backup to Mac OS X over the Internet

The Request:

I was engaged by a long time client who was having an issue with their local SFTP1 server. After some upgrades to their server infrastructure they noticed their phone/voicemail system had not been backed up in MONTHS! They asked if there was a way for me to perform an “emergency” backup to my system if they gave the voice VLAN access to the Internet temporarily while they fixed their SFTP issues.

Cisco Translation Rules, CDRs, and Unity Connection

The Request:

I had a new client contact me requesting that I investigate a call that came in over the weekend where an external customer was able to leave a voicemail on an internal users extension, using the corporate IVR, instead of being routed to the weekend service. This behavior was unacceptable and caused much concern throughout the leadership. The client provided me the internal extension where the voicemail was left and a timeframe. Since I was relatively new to the system I was excited to get my hands dirty and really investigate the routing. As all voice engineers know, coming into a system someone else built can always be an adventure…

Cisco VRF/MP-BGP Router On A Stick With Nat

The Request:

I was approached by a client who wanted me to build their multi tenant network for a small office building. During the initial meeting it came out that they already had equipment and would like to use this equipment without purchasing much more. This is what I had to work with:

  • 1 x Cisco X8XX Series ISR1
  • 6 x Cisco 2960X Switches

The client also has an existing Cisco Unified Communications System that they will be configuring to provide voice services to all of the tenants. There will be no LAN-to-LAN communications between the tenants. There will be a reasonable amount of commercial grade Internet access and the tenants will be allowed to host some services locally (e-mail, collaboration software, etc.).
