Annoying ethernet command

I really hate on a switch the way i have to complete the command ethern otherwise the cli is confused with etherchannel. As i annoys me, i wanted to use alias to get past this but it doesn't work, strange. I'm not really a fan of using aliases but in this case it could have made my life easier.

Yea, you got to love it. I was setting up a new data center last month with ASA, IOS, IOS-XE, NX-OS it was fun remembering which box I was in and which syntax I needed to use, etherchannel/port-channel, snmp syntax, etc fun times!

and I had to alias's for 'wr' in NX-OS

-along with an alias for switching VDCs cause I got lazy

To get your command to work you have to match from the beginning of the command and cannot use it in the middle like you're trying to do here.

Here's an example:

Switch(config)#alias exec EdTheLad show int gi
Switch(config)#do EdTheLad 1/0/1
GigabitEthernet1/0/1 is up, line protocol is up (connected)
  Hardware is Gigabit Ethernet, address is 0019.5577.3581 (bia 0019.5577.3581)

So in your case something like this might serve you well:
"alias exec show show interface ethernet"
show 0/0

HTH,
Happy New Year

I do this now too, for wr, all switchto and for switchback from all VDCs. I learned the hard way that if you are typing too fast in configuration mode that "swicthback" can become "switch b" and then you've renamed your vdc to "b" due to the "switchname" command.

LAB-7K1# sh vdc

vdc_id vdc_name

1 LAB-7K1
2 DC-1

LAB-7K1# swd1

LAB-7K1-DC-1# con
LAB-7K1-DC-1(config)# swi b <

OOPS
LAB-7K1-b(config)# sb <

Its hostname is now "b"
LAB-7K1# sh vdc

vdc_id vdc_name

1 LAB-7K1
2 b <

VDC name b

Good times.
