Net::Telnet::Cisco::IOS

Hi
today I tried the example of the methods list:

...
my $int = "vlan1";
%state = $conn->getIntState( $int );
print "Interface $int has a port state of $state{ 'port' }.\n";
print "It also has a protocol state of $state{ 'lineprotocol' }.\n";

This gives the messages:
Use of uninitialized value in concatenation (.) or string at telnetIOS.pl
line 23.
Interface vlan1 has a port state of .
Use of uninitialized value in concatenation (.) or string at telnetIOS.pl
line 24.
It also has a protocol state of .

It seems to me that the &harmonizeInts changes the input to VLAN1 which is
compared to the output of a switch:

#sho int vlan1
Vlan1 is up, line protocol is up
Hardware is EtherSVI, ....

Because VLAN1 is not Vlan1 there is no match.

For a test I modified in IOS.pm , sub getIntState the line
if ( $line =~ /$if is (.+), line protocol is (.+) / ) {
to
if ( $line =~ /$if is (.+), line protocol is (.+) /i ) { # Do
case-insensitive pattern matching

That seems to work in this case.
