This was a busy week. Last weekend I performed some hardware maintenance on Cisco 6506, continued deployment of a MSSP integration and had some time with a DMVPN deployment and troubleshooting. When time permitted I was reviewing CCIE OSPF Material.

Continuing on my hardware upgrades , I swapped a 4 x 10G card for the 16 port variety and did some new fiber run to comply with an LC Fiber form factor. For some reason the previous engineer had one side LC and another SC which drove me nuts. I did add some labeling and well . The only stand out item was in order to allow for the change. I needed to gain some power on the chassis for the 16 port cards. I also swapped out the 2500W Power Supply units for the 3000W variety. The power allocation was just under the 24 Amps allowed on the PDU combined but it did the trick.

A great deal of the time this week was ensuring proper integration with my firewalls and other devices were properly logging to my Alienvault SIEM service. I came to a better understanding of how the service depends on the Device Category and how it fits into the service plug-ins and event detection. Testing was successful for static defined alerts. I plan to run some test next week for some of the Correlation Events the system can detect.

A few months ago, I deployed dmvpn solution and was engaged to an issues with the customer having packet loss issues. The return traffic was learning a path back to the hub via a peer spoke instead of the hub network.

I have a new site to deploy which I will put together more in my next post.
