\n0. \u00davodn\u00ed slovo, nebo trochu off-topic<\/b>Tento \u010dl\u00e1nek vznikl pouze proto, \u017ee je velmi t\u011b\u017ek\u00e9 naj\u00edt srovn\u00e1vac\u00ed charakteristiky podobn\u00e9ho softwaru, nebo dokonce jen seznam na jednom m\u00edst\u011b.

1. Teorie<\/h2>\n

<\/p>\n

1.1. Pro\u010d?<\/h3>\n

\nAbychom odpov\u011bd\u011bli na ot\u00e1zku \u201ePro\u010d?\u201c, je nejprve pot\u0159eba pochopit, co to vlastn\u011b je \u201eMapa s\u00edt\u011b\u201c. Mapa s\u00edt\u011b \u2013 (nej\u010dast\u011bji) logicko-grafick\u00e9 sch\u00e9ma interakce s\u00ed\u0165ov\u00fdch za\u0159\u00edzen\u00ed a jejich vztah\u016f, kter\u00e9 popisuje jejich nejv\u00fdznamn\u011bj\u0161\u00ed parametry a vlastnosti. Dnes se \u010dasto pou\u017e\u00edv\u00e1 v kombinaci s monitoringem stavu za\u0159\u00edzen\u00ed a syst\u00e9mem upozorn\u011bn\u00ed. Tak\u017ee: abychom m\u011bli p\u0159edstavu o rozlo\u017een\u00ed uzl\u016f s\u00edt\u011b, jejich interakci a vazb\u00e1ch mezi nimi. V kombinaci s monitoringem m\u00e1me pracovn\u00ed n\u00e1stroj pro diagnostiku chov\u00e1n\u00ed a p\u0159edpov\u011b\u010f chov\u00e1n\u00ed s\u00edt\u011b.<\/p>\n

1.2. L1, L2, L3<\/h3>\n

\nJsou to Layer 1, Layer 2 a Layer 3 v souladu s modelem OSI. L1 \u2013 fyzick\u00e1 \u00farove\u0148 (dr\u00e1ty a p\u0159ep\u00edn\u00e1n\u00ed), L2 \u2013 \u00farove\u0148 fyzick\u00e9ho adresov\u00e1n\u00ed (MAC adresy), L3 \u2013 \u00farove\u0148 logick\u00e9ho adresov\u00e1n\u00ed (IP adresy).
\n<\/a><\/noindex>
\nNen\u00ed smyslupln\u00e9 vytv\u00e1\u0159et mapu L1, ta logicky vypl\u00fdv\u00e1 z L2, snad krom\u011b m\u00e9diov\u00fdch p\u0159evodn\u00edk\u016f. A i ty nyn\u00ed existuj\u00ed m\u00e9dii, kter\u00e9 lze tak\u00e9 sledovat. <\/p>\n

Logika je takov\u00e1, \u017ee L2 vytv\u00e1\u0159\u00ed mapu s\u00edt\u011b na z\u00e1klad\u011b MAC adres uzl\u016f, L3 \u2013 na z\u00e1klad\u011b IP adres uzl\u016f.<\/p>\n

1.3. Jak\u00e1 data zobrazit<\/h3>\n

\nZ\u00e1vis\u00ed to na \u0159e\u0161en\u00fdch \u00faloh\u00e1ch a po\u017eadavc\u00edch. J\u00e1 nap\u0159\u00edklad chci samoz\u0159ejm\u011b pochopit, zda je samotn\u00e9 za\u0159\u00edzen\u00ed '\u017eiv\u00e9', na jak\u00e9m portu co 'vis\u00ed' a v jak\u00e9m stavu je port \u2013 up nebo down. To m\u016f\u017ee b\u00fdt L2. A v\u016fbec mi L2 p\u0159ijde jako nejvhodn\u011bj\u0161\u00ed topologie s\u00ed\u0165ov\u00e9 mapy v praktick\u00e9m smyslu. Ale, co se vkusu t\u00fd\u010de...<\/p>\n

Rychlost p\u0159ipojen\u00ed na portu \u2013 to nen\u00ed \u0161patn\u00e9, ale nen\u00ed to kritick\u00e9, pokud je tam koncov\u00e9 za\u0159\u00edzen\u00ed \u2013 tisk\u00e1rna nebo PC. Bylo by dobr\u00e9 m\u00edt mo\u017enost pod\u00edvat se na \u00farove\u0148 vyu\u017eit\u00ed procesoru, mno\u017estv\u00ed voln\u00e9 opera\u010dn\u00ed pam\u011bti a teplotu za\u0159\u00edzen\u00ed. Ale to u\u017e nen\u00ed tak jednoduch\u00e9, zde bude t\u0159eba nastavit monitorovac\u00ed syst\u00e9m, kter\u00fd um\u00ed \u010d\u00edst SNMP a vykreslovat a analyzovat z\u00edskan\u00e1 data. O tom pozd\u011bji.<\/p>\n

Co se t\u00fd\u010de L3, na\u0161el jsem tohle \u010dl\u00e1nek<\/a><\/noindex>. <\/p>\n

1.4. Jak?<\/h3>\n

\nLze to ud\u011blat ru\u010dn\u011b, nebo automaticky. Pokud rukou \u2013 tak to trv\u00e1 dlouho a je t\u0159eba br\u00e1t v \u00favahu lidsk\u00fd faktor. Pokud automaticky \u2013 je t\u0159eba zv\u00e1\u017eit, \u017ee v\u0161echna s\u00ed\u0165ov\u00e1 za\u0159\u00edzen\u00ed mus\u00ed b\u00fdt 'inteligentn\u00ed', um\u011bt SNMP a tento SNMP mus\u00ed b\u00fdt spr\u00e1vn\u011b nastaven, aby syst\u00e9m, kter\u00fd bude shroma\u017e\u010fovat data, mohl tyto \u00fadaje na\u010d\u00edst.<\/p>\n

Na prvn\u00ed pohled to nevypad\u00e1 slo\u017eit\u011b. Ale jsou tu skryt\u00e9 komplikace. Za\u010d\u00edn\u00e1 to t\u00edm, \u017ee ne ka\u017ed\u00e1 systema bude schopn\u00e1 na\u010d\u00edst ze za\u0159\u00edzen\u00ed v\u0161echny ty data, kter\u00e9 bychom cht\u011bli vid\u011bt, nebo ne v\u0161echna s\u00ed\u0165ov\u00e1 za\u0159\u00edzen\u00ed mohou tyto data vyprodukovat, a kon\u010d\u00ed t\u00edm, \u017ee ne ka\u017ed\u00fd syst\u00e9m um\u00ed s\u00e1m automaticky vytv\u00e1\u0159et s\u00ed\u0165ov\u00e9 mapy.<\/p>\n

2. Praxe<\/h2>\n

\nTak\u017ee, te\u010f si promluvme o tom, jak lze sestavit s\u00ed\u0165ovou mapu. Vezmeme za v\u00fdchoz\u00ed bod, \u017ee chceme, samoz\u0159ejm\u011b, tento proces co nejv\u00edce automatizovat. No, to znamen\u00e1, \u017ee Paint a MS Visio vypad\u00e1vaj\u00ed... i kdy\u017e... ne, po\u0159\u00e1d vypad\u00e1vaj\u00ed.<\/p>\n

Existuje specializovan\u00fd software, kter\u00fd \u0159e\u0161\u00ed \u00fakol vytv\u00e1\u0159en\u00ed mapy s\u00edt\u011b. N\u011bkter\u00e9 programov\u00e9 produkty mohou pouze poskytnout prost\u0159ed\u00ed pro \"ru\u010dn\u00ed\" p\u0159id\u00e1n\u00ed obr\u00e1zk\u016f se vlastnostmi, vykreslov\u00e1n\u00ed vazeb a spou\u0161t\u00ed \"monitoring\" v siln\u011b omezen\u00e9 podob\u011b (je uzel \u017eiv\u00fd, nebo u\u017e neodpov\u00edd\u00e1).
