Junos OS

Is there a way to change the system prompt to somethign different then the hostame?

 

dhanks@MX80> set cli prompt ?
Possible completions:
  <cli-prompt>         CLI command prompt string
dhanks@MX80> set cli prompt

 

 

Hi,

 

You can try "set cli prompt" command.

Thanks guys. This does work but as soon as I log out it goes back to what it was. Anyway to make it permanent?

Junos only supports temporary prompt changes.

 

There's no permanent way to change the prompt.  We intentionally limit the customization so that Junos is able to maintain its look and feel.

Makes sense.  I basicly have this problem:

 

I have a router in many different cities.  The router perform the same function in each city so we give it the same hostname in each city.  The domain the router is part of is different.

 

ex) Router in Vancouver is WanRouter  but its FQDN is WanRouter.VAN.company.com

      Router in LA is WanRouter but tis FQDN is WanRouter.LA.company.com

 

my issue is when I SSH the prompt alwasy just says  root@WanRouter>

 

I could just change the hostname to be WanRouter-LA but then my FQDN is WanRouter-LA.LA.company.com which looks silly.

 

Any suggestion?

Don't use sub-domains 😉

 

I also suggest the following hostname scheme:

 

AIRPORT-FUNCTION-DEVICE-NODE-PROCESSOR.domain.com

 

LAX-WAN-MX80-01-RE0.domain.com

 

Also apply DNS to each interface as well so that your traceroute is pretty.

 

AIRPORT-FUNCTION-DEVICE-NODE-PROCESSOR-PORT.domain.com

 

LAX-WAN-MX80-01-RE0-xe-0/0/0.domain.com

 

Use the apply-groups if you have a router with two routing engines.

Thanks for the great Tip. 

 

Can you show me an example of applying DNS on each interface.  I thought it would just always take the system's DNS.

There's no Junos configuration for that.

 

For example if your IP on xe-0/0/0.0 was 10.0.0.1/30, you would simply add an entry into DNS for 10.0.0.1 with the extended hostname.
