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 icon_smile.gif -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)

  Encapsulation ARPA, loopback not set
  Keepalive set (10 sec)
  Full-duplex, 1000Mb/s, media type is 10/100/1000BaseTX
  input flow-control is off, output flow-control is unsupported
  ARP type: ARPA, ARP Timeout 04:00:00
  Last input 00:00:01, output 00:00:03, output hang never
  Last clearing of "show interface" counters never
  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
  Queueing strategy: fifo
  Output queue: 0/40 (size/max)
  5 minute input rate 27000 bits/sec, 2 packets/sec
  5 minute output rate 4000 bits/sec, 3 packets/sec
     131418103 packets input, 109444749754 bytes, 0 no buffer
     Received 1186091 broadcasts (767580 multicasts)
     0 runts, 0 giants, 0 throttles
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
     0 watchdog, 767580 multicast, 352 pause input
     0 input packets with dribble condition detected
     103730060 packets output, 33974237602 bytes, 0 underruns
     0 output errors, 0 collisions, 1 interface resets
     0 babbles, 0 late collision, 0 deferred
     0 lost carrier, 0 no carrier, 0 PAUSE output
     0 output buffer failures, 0 output buffers swapped out
Switch(config)#do EdTheLad 1/0/1 status

Port      Name               Status       Vlan       Duplex  Speed Type

Switch(config)#

    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.
