After being six times at Cisco Live Europe between 2009 and 2016, this year my management allowed me to go to Cisco Live US. I registered last week and now I am starting to see some rumors about the customer appreciation event (CAE) and the keynote speakers.
On Cisco routers, by default the BGP protocol will not do load-sharing – and even less unequal cost load-sharing – across multiple links, for traffic to the same eBGP destination with different AS-path. Let’s see how we can change this.
The Cisco Embedded Event Manager or Cisco EEM is a software component of Cisco IOS, IOS-XR, and NX-OS that provides real-time network event detection and onboard automation.
EEM allows you to automate tasks, perform minor enhancements and create workarounds and can makes life easier for network operators by tracking and classifying events that take place on a network device and providing actions options for those events.
Recently, a customer called me to configure Netflow on these routers because he just installed NetFlow Analyzer software from ManageEngine. This software is an “all in one” NetFlow collector, database, WebUI software, able to build pretty nice reports.
In my opinion, Netflow is one of the absolutely required software to have a good visibility when you operate a network. Continue reading “Cisco Flexible Netflow configuration”
Configuring a LACP link aggregation, EtherChannel, or port-channel, or Eth-trunk between Huawei and Cisco switch is something very common. But since the configuration syntax between the two vendors is different, it can be confusing.
In this article, I will show how to configure a LACP port-channel – called Eth-trunk on Huawei – properly between a Cisco catalyst switch running IOS or IOS-XE and a Huawei switch, model 6700 in this case.
The GUI application to use Cisco VIRL, VM Maestro, comes with a basic internal Telnet and SSH client called “Cisco Terminal”.
If, like me, you want to use the rock-solid SecureCRT as terminal emulator client, you need to change the the VM Maestro preferences. Continue reading “How to setup Cisco VIRL, VM Maestro to use SecureCRT as default terminal”
