+# EtherChannel
+
+- propojení switchů přes několik linek (drátů), zvýší spolehlivost a rychlost
+- musí být stejná rychlost, technologie, vlan
+- až 8 linek
+- nelze mixovat rychlosti ani technologie (Fast Ethernet a Gigabit nejde mixovat, ani ostatní)
+- defaultně [Spanning Tree Protocol](Spanning%20Tree%20Protocol.md) vypne kabel, musí se proto nastavit EtherChannel. 
+- konfiguruje se přes jeden interface, zařídí jednotnou konfiguraci mezi více fyzickýma interface.
+
+## PAgP
+
+- zajišťuje automatické nastavení rychlosti, STP a kontroluje že linka funguje.
+- posílá pakety každých 30 vteřin
+- cisco proprietární
+
+### Mode
+
+- **on** - manuální nastavení EtherChannel 
+- **Desirable** - Automatické nastavení přes PAgP
+- **Auto** - Automatické nastavení přes PAgP, ale nezačne komunikaci (druhý switch musí být na **Desirable**)
