Invalid input detected - Extreme VOSS 8.1.10

[eliandawg]

• [ X] I have read and understood docs/Issues.md.

Describe the bug
The VOSS model views the running configuration by using the more config.cfg command, but the more command is not available on a VSP-7400-48Y-8C running Extreme VOSS 8.1.10.0. Newer versions (for me, Extreme VOSS 9.1.2.0 work as expected.

EDIT: Should've checked before, but the command does go through when running as the rwa user, although I'd rather use a read-only account for configuration backups.

To Reproduce
Steps to reproduce the behavior:

1. Configure authentication with a read-only user.
2. Use model voss.
3. Run the backup
4. See error

# vsp-sw-1:1#
# more config.cfg
                    ^
% Invalid input detected at '^' marker.

Expected behavior
The running configuration should be listed, but I only see an error when running the more command.

It is not clear to me what the expectation here is. What are you asking?

[eliandawg]

The more command doesn't seem to be available for a user configured as read-only in VOSS (at least for 8.1.10.0), so the running configuration isn't shown when running a backup job when authenticating with a read-only user. The command is available for read/write users, but I would prefer to have the backup user be read-only

# vsp-sw-1:1#
# more config.cfg
                    ^
% Invalid input detected at '^' marker.

  # more the config rather than doing a show run
  cmd 'more config.cfg' do |cfg|
    cfg.gsub! /^[^\s#>]+[#>]$/, ''
    cfg.gsub! /^more config.cfg/, '# more config.cfg'
    cfg
  end

So what command works in RO? Whats the difference in output?

[eliandawg]

The regular show running-config command works fine as the RO user. The difference in output is that config.cfg is the last written configuration, not the current running configuration, plus some extra lines showing the command execution time.

show running-config:

We probably should have input from @ospfbgp to understand their decision
