I think you will need to look at what you actually get in the result to the
SNMP query by running it manually and then decide what you will need to
compare it to.
There is a second hook in "goodies/hooks.txt" (included below) which does
fancier things with the encoded NAS-Port that you can optionally set in the
Cisco configuration.
# cisco-nas-port.pl
# PreClientHook to extract NAS-Port information.
#
# Cisco encodes information in the NAS-Port attribute as follows:
#
# nl-rt-sh-vpn-aer11(config)#radius-server attribute nas-port format ?
# a Format is type, channel, port
# b Either interface(16) or isdn(16), async(16)
# c Data format(bits): shelf(2), slot(4), port(5), channel(5)
# d Data format(bits): slot(4), module(1), port(3), vpi(8), vci(16)
#
# This hook is written for Cisco format "d" above (ATM vpi/vci).
#
# The encoded information is extracted and the individual data elements
# are added to the request packet as pseudo-attributes.

my $p = ${$_[0]};
my $nasport = $p->get_attr('NAS-Port');
if (defined($nasport))

my ($slot, $module, $port, $vpi, $vci);
$vci = $nasport & 0xffff;
$nasport = $nasport >> 16;
$vpi = $nasport & 0xff;
$nasport = $nasport >> 8;
$port = $nasport & 0x7;
$nasport = $nasport >> 3;
$module = $nasport & 0x1;
$nasport = $nasport >> 1;
$slot = $nasport & 0xf;
$p->add_attr('Cisco-NAS-Port-Vci', $vci)
if defined $vci;
