Cisco Mac Question
When I do a snmpwalk of my router the mac address are not what I expected.

Then return looking like this
Quote:
0:1c:c9:2a:b6:77
How would you convert them to 001c.c92a.b677 when a shell script?

Awful long but works:
Code:
echo "0:1c:c9:2a:b6:77"| tr -s ':' '\n'|  sed 's/^.$/0&/'| tr -d '\n'| sed 's/\(....\)\(....\)\(....\)/\1\.\2\.\3\n/g'
001c.c92a.b677

Here is a pure shell solution using ksh93
Code:
#!/usr/bin/ksh93

MAC="0:1c:c9:2a:b6:77"

IFS=":" typeset -a array=($MAC)

outmac=""
for ((i = 0; i < 6; i++))
do
   (( ${#array[i]} < 2 )) && outmac="${outmac}0"
   outmac="${outmac}${array[i]}"
   (( i < 5 && (i % 2) == 1 )) && outmac="${outmac}."
done

echo "$MAC --> $outmac"

which gives the following output
Code:
0:1c:c9:2a:b6:77 --> 001c.c92a.b677
