When input a series of MAC addresses, must put in colon between each number pair as 00:60:08:20:85:E3. When typing in large numbers of these into hotspot automatic MAC login, it is tedius. I agree that the MACs are easier to read with the colon punctuation. How about making the input parser accept MACs both with colons and as number strings as 0060082085E3 and convert them to the usual colon delimited format.
this is already possible in the latest versions. look :
[admin@router] ip arp> add mac-address=010203040506 interface=ether1
[admin@router] ip arp> print
Flags: X - disabled, I - invalid, H - DHCP, D - dynamic
# ADDRESS MAC-ADDRESS INTERFACE
0 0.0.0.0 01:02:03:04:05:06 ether1
