no switchport mode dynamic desirable

mode access to mode trunk

I got a Cisco 2950 swicth where a port is configured "access vlan 54". I want to make vlan 54 native on this and put a vlan 150 over it.

I then have to enter something like:

 interface FastEthernet0/4  description vers switch admin1 fa0/17  switchport trunk encapsulation dot1q  switchport trunk native vlan 54  switchport trunk allowed vlan 54,150  no cdp enable
Unfortunately, when runnnig the configuration, I get: 
 interface FastEthernet0/4  description vers switch admin1 fa0/17  switchport trunk encapsulation dot1q  switchport trunk native vlan 54  switchport trunk allowed vlan 54,150  switchport mode dynamic desirable  no cdp enable
Whatever I tried, I always got the "switchport mode dynamic desirable"...

no, then mode trunk

The solution was to negate the dynamic and directly force trunk. I entered the configuration in this order:

 interface FastEthernet0/4  no  switchport mode dynamic desirable  switchport mode trunk  switchport trunk encapsulation dot1q  switchport trunk native vlan 54  switchport trunk allowed vlan 54,150  no cdp enable
I'm done!

npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='https://ngx.rktmb.org/foo' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin. I got the habit to build the application with "npm run build" before deploying it. But the development team once asked me to set the "--base-href='https://ngx.rktmb.org/foo'" parameter. npm run build --base-href='https://ngx.rktmb.org/foo did not set the base href in indext.html After looking for a while, I found https://github.com/angular/angular-cli/issues/13560 where it says: You need to use −− to pass arguments to npm scripts. This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo&
