Dynamic Access Lists solve a different problem that traditional ACLs cannot solve quickly. Imagine a few users accessing a set of servers. ACLs match user host IP addresses. The legitimate user’s IP address changes if she borrows a PC, uses DHCP, takes her laptop home, etc. Each new IP address requires editing a traditional ACL. This caused painful administration and security holes.
An extended access list, a reflexive access list allows for the dynamic combination of two access lists. If the outbound access list recognizes a remote connection, the inbound access list will be activated to permit bidirectional traffic. With the conclusion of this interactive session, the remote host is once again denied access to the inbound access list.

Cisco Catalyst 9000 StackWise Virtual Link merges two physical switches into one. Both switches’ configuration and forwarding state are identical. This technology improves the network availability, scalability, management, and maintenance.
This article will discuss how to upgrade IOS-XE on switches belonging to the catalyst 9000 series.
When you draw or paint anything, you don’t imitate it; that’s photography. To paint a tree, flower, or sunset. You must feel its meaning and significance. We never touch a tree, feel its solidity or rough bark, or hear its sound. Not the wind through the leaves or the morning breeze that flutters them, but we must listen to…
When starting the project planning process, the first things to think about are:
What could be the show-stopper? It may sound negative, but realistic project managers know this kind of thinking is preemptive. Problems will inevitably arise, so knowing how to manage risk in your project plan requires a risk mitigation strategy.
According to a January 1996 paper published by Gartner Group , inadequate stakeholder engagement and infrequent communication with sponsors were the primary causes of project failure. Although these findings first surfaced decades ago, the findings remain more important than ever.
