To enhance my previous code a bit. One could also add regular expressions for finding the version etc. from the string like this (example given just for Cisco)

my(%manufacturers)= (
    Cisco        => {
        key => qr/Cisco/i,
        version => qr/Internetwork.*(C[0-9]+[a-zA-Z]*?)|Cisco\s+(\d+)|
+Cisco\s+(AP\w+)/,
        # the re will pick any possible Version number in $1.. $n
    },

    'TUT Systems'=> {
        key => qr/Expresso GS|MDU Lite/i,
        version => qr//, 
    },
    Gigalink     => {
        key => qr/Gigalink/i,
        version => qr//, 
    },
    Huawei       => {
        key => qr/Huawei/i,
        version => qr//, 
    },
    Orinoco      => {
        key => qr/AP-2000|AP-1000/i,
        version => qr//, 
    },
    Lucent       => {
        key => qr/WavePOINT/i,
        version => qr//, 
    },
    HP           => {
        key => qr/HP/,
        version => qr//, 
    },
    Paradyne     => {
        key => qr/Paradyne/i,
        version => qr//, 
    },
    Colubris     => {
        key => qr/CN320/,
        version => qr//, 
    },
    SMC          => {
        key => qr/TigerSwitch/,
        version => qr//, 
    },
    Ricoh        => {
        key => qr/RICOH/,                         
        version => qr//, 
    },
);
