1. Config CIMC (Cisco Integrated Management Controller)

– Connect Display/Mouse to UCS, and FJ45 to CIMC Port

– Power on UCS, then press F8, config IPv4/GW, as follow

2. Config FlexFlash

– Login CIMC address by web

– Config “Auto Sync” in “Configure Cards”, and waiting sync complete

– After sync, enable “Hypervisor” in “Virtual Drives”

– Then login in virtual console by “Launch KVM” -> “HTML based KVM”

– “Activate Virtual Decvices” and mapping ESXI image

– After complete installing, set FlexFlash boot priority in “Configure BIOS Order”

Attentation:

At first there was follow alarm when install ESXI, that due to SD Card of FlexFlash not empty, so you need boot with GParted first, then remove original “fat32 disk”, then “Create Partition Table…”. After completed this task, then install ESXI.

Introduction

Now more customer complains their Peering network not flexible and hard to control, that will cause peering link’s utilization not balance and waste of resources. As follow the example on Router-2, customer peering device connect to multi ISP, each ISP sends full internet route, select only based on the BGP. BGP select rule only based on the route but not real traffics, that may be cause port-A’s traffics have 8G, but port-B and port-C only have 4G, if want to adjust BGP select, only change RPL that more complex, and due to route from internet and multi ISP, so route maybe change at some time, in order to balance peering link, customer must continue to adjust their RPL.

Could we have more flexible and simplest way to resolve the issue? The answer is Yes 🙂 we can achieve the task by Segment Routing – Egress Peer Engineering. Now some customer had deployed the solution, that combine NetFlow, Openbmp to check AS/traffics of prefix, then send BGP LU(EPE label) to ingress node, and easy to control traffics.

Introduction

I installed the WAE 6.4.5 at formal and summaried to Blog, e.g: INSTALL CISCO WAE 6.4.5. After 7.0, install/config have big change and similar with NSO that easy/module to deploy. For this article, only talk about how to install and enable.

Auto source profile

Similar with NSO, add “source” command to “.bash_profile” that in MacOS. That will let you direct to login to WAE but not do “source wae711/waerc”, as follow:

[root@frank ~]# echo "source /opt/wae711/waerc" >> .bash_profile
[root@frank ~]# more .bash_profile | grep wae
source /opt/wae711/waerc

部署虚拟开发环境

虽然自己不是软件工程师，但有时候为了测试会写一些小程序，所以常常需要在自己电脑上设置开发环境。由于MacOS原生支持Python，所以我们可以不用那么麻烦的设置开发环境。但为了系统的稳定性，还是不要随便增加或变更自带的python，所以开发环境直接用虚拟环境就可以了，大概构架如下：
