[c-nsp] privilege exec ... unexpected behaviour

["Rolf Hanßen"]

Hello,

Following Setup:
I created a User with no privileges and want to allow some commands. I
configured:
privilege exec level 0 show bgp ipv6 unicast
privilege exec level 0 show bgp ipv4 unicast
privilege exec level 0 show ip bgp
privilege exec level 0 show ip route
All commands were accepted by the cli.

I then access the device with the limited user.
Those commands work fine:
show ip route 1.2.3.4
show ip bgp 1.2.3.4

But the "sh bgp ..." commands fail:
Router>show bgp ?
  all       All address families
  ipv4      Address family
  ipv6      Address family
  l2vpn     Address family
  nsap      Address family
  rtfilter  Address family
  vpnv4     Address family
  vpnv6     Address family

Router>show bgp ipv4 ?
% Unrecognized command
Router>show bgp ipv4

The Config file also does not list the commands.
Router#sh running-config | inc privilege exec
privilege exec level 0 show bgp
privilege exec level 0 show ipv6 route
privilege exec level 0 show ipv6
privilege exec level 0 show ip bgp
privilege exec level 0 show ip route
privilege exec level 0 show ip
privilege exec level 0 show


Is there some additional config needed or is it some kind of
restriction/limitation ?

Hardware is Sup2T
Software is 15.0(1)SY2

kind regards
Rolf
