This has two problems.

First and foremost, you cannot nest single quotes in single quotes. You can't escape anything in single quotes either, so not even backslashes will fix it. You'll have to put double quotes on the outside.

Second, not all systems have gawk. In fact very few systems have gawk; even systems like Linux which default to it just call it awk.

Your awk command is simple enough that hopefully vanilla awk can handle it, even the awful old versions some systems have.

Code:
for server in test1 test2; do ssh $server "/usr/listinfo policy -L | awk 'NR == 2'";done

igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION

OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
