Hi geovane95,
I'm assuming you're using some Cisco IOS version.
The equivalent to the Cisco IOS command "Show" is the HP comware command "Display".
so
1: show version ~ display version
2: show running-config ~ display current-configuration
3: show ip interface brief ~ display ip interface brief
4: show interfaces trunk:
There is no direct "translation" a comware command here. But "display interface brief" and "display port trunk" might both create the output you're looking for.
5: show cdp neighbors
Well the HP series run lldp and not cdp. Depending on what output you expect, you might want to run a "display lldp neighbor-information list"
6: show vlan
I havent found a command that does exactly what Cisco IOS "show vlan" does, however you can do : "display current-configuration configuration - and the output you look for will be part of that, or you can do :
vlan 1
display this
which is 2 commands.
7: show ip protocols :
there is no one command for this, but try.
display ip routing-table protocol [bgp,direct,isis,ispf, rip, static] verbose
8: show ip route ~ display ip routing-table (verbose)
where verbose is optional.
Regards
