Request New Feature: 'nxos' prompt

[miguecor]

I work a lot with Cisco NX-OS switches. These switches change the prompt depending on the configuration level you are at.

It would help greatly to a lot of Network Engineers if we could add prompts for Cisco devices. Here's an example of how the prompt behaves:

switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# interface ethernet1/1
switch(config-if)# exit
switch(config)# router bgp 65501
switch(config-router)# address-family ipv4 unicast
switch(config-router-af)# exit
switch(config-router)# neighbor 10.101.0.1
switch(config-router-neighbor)# address-family ipv4 unicast
switch(config-router-neighbor-af)# exit
switch(config-router-neighbor)# exit
switch(config-router)# exit
switch(config)# interface vlan 100
switch(config-if)# hsrp 1
switch(config-if-hsrp)# exit
switch(config-if)# exit
switch(config)# exit
switch#

As you can see, there are multiple configuration levels. These are just some examples. The commands to jump into each configuration level are very static, maybe this would make it easier to implement. Maybe a JSON file with the prompt and the regex that triggers the next prompt would work and also would allow the user to expand the initial file if needed.

If you consider implementing this prompt and need some help defining the different prompt levels, please reach out to me.

Thanks!

I can look at it, but unfortunately I am currently very busy in other projects, so it might take a while. I add this to my todo list as well. Are these the only keywords that trigger a prompt change (if, exit, router, address-family, neighbor,hsrp) or are there any more? Or maybe is there somewhere a documentation which lists all of them? Although I would need one, which also lists to what the prompt changes, because as I see there are exceptions e.g. address-family --> af

Those are not the only ones. There might be at least a hundred of them. The word itself is not what takes you into the next configuration mode always.

Some examples:

interface Ethernet<slot>/<port>
interface Vlan<vlan_no>
interface loopback<id>
interface port-channel<po_no>

Will take you into interface-configuration-mode: config-if

router bgp <asn>
router ospf <proc_id>
router eigrp <as>

Will take you into router-configuration-mode.

The command modes are only referenced in the NX-OS command guides:
https://www.cisco.com/c/en/us/td/docs/dcn/nx-os/nexus9000/105x/command-reference/config/b_n9k_config_commands_1051/m_a_cmds.html

Each command specifies in what configuration mode it needs to be executed.

If you could point me into the files that need modification, I could try to make the changes myself and then create a PR for your review.

Thanks a lot for taking the time to read me :)

The files that handles prompts are PromptManager and PromptUtils . The logic is not quite the best. It is a little messy. I wanted to clean that up, but didn't had the time. If you are able to figure it out, and submit a PR that would be great. If not, that is not a problem, and I'll do it later.
