   • CONFIGURE ETHERCHANNEL
     • CONFIGURATION GUIDELINES
       • ETHERCHANNEL SUPPORT
       • SPEED AND DUPLEX
         • ALL INTERFACES MUS BE SAME SPPED AND DUPLEX MODE
       • VLAN MATCH
         • ALL INTERFACES IN CHANNEL MUS BE ASSIGNED SAME VLAN
       • RANGE OF VLANs
         • SAME ALLOWED RANGE OF VLAN
       • CHANNEL IS FORMED WHEN CONFIGURATION SETTINGS MATH ON BOTH SWITCHES
       • CAUTION : SETTINGS MUT BE CHANGED ?
         • CONFIGURE THEM IN PORT CHANNEL INTERFACE CONFIGURATION MODE
           • CONFIGURATION APPLIED INDIVIDUAL INTERFACES DO NOT EFFECT THE PORT CHANNEL
         • ANY CONFIGURATION APPLIED TO THE PORT CHANNEL
           • AFFECTS INDIVIDUAL INTERFACES
     • LACP CONFIGURATION EXAMPLE
       • 1) SPECIFY THE INTERFACES THAT COMPOSE THE ETHERCHANNEL GROUP
         • (CONFIG)# INTERFACE RANGE FASTETHERNET 0/1-2
       • 2- CREATE THE PORT CHANNEL INTERFACES
         • (CONFIG-IF-RANGE)#CHANNEL-GROUP 1 MODE PASSIVE
         • (CONFIG-IF-RANGE)#CHANNEL-GROUP 1 MODE ACTIVE
       • 3) CHANGE LAYER 2 SETTINGS ON THE PORT CHANNEL
         • (CONFIG)#INTERFACE PORT-CHANNEL 1
           • (CONFIG-IF )# SWITCHPORT MODE TRUNK
           • (CONFIG-IF )# SWITCH TRUNK ALLOWED VLAN 1,10,20

     • DISPLAYS THE GENERAL STATUS OF THE PORT CHANNEL
       • S1#SHOW INTERFACES PORT-CHANNEL
     • INTERFACES ARE CONFIGURED IN CHANNEL ; DIAPLAY LINE OF INFORMATION PER PORT CHANNEL
       • S1#SHOW ETHERCHANNEL SUMMARY
         • THE ORDER IN WHICH EHETCHANNEL COMAMNDS IS IMPORTANT , STP AND ETHERCHANNEL INTEROPERATE
     • COMMOM ISSUES WITH ETHERCHANNEL CONFIGURATIONS ?
       • CANNOT FORM AN ETHERCHANNEL
         • PORTS ARE NOT IN THE SAME VLAN OR ARE NOT CONFIGURED AS TRUNKS
         • PORTS WITH DIFFERENT NATIVE VLANS
         • TRUNKING IS CONFIGURED ON ONLY SOME MEMBER PORTS
         • TRUNK CONFIGURATION MUST BE APPLIED ON THE PORT-CHANNEL, NOT ON INDIVIDUAL PORTS
         • ALLOWED VLAN RANGE IS NOT THE SAME ACROSS ALL PORTS
         • PAgP OR LACP NEGOTIATION SETTINGS ARE NOT COMPATIBLE ON BOTH ENDS
     • CAN PROVIDE INFORMATION ABOUT THE ROLE OF INTERFACE IN THE ETHERCHANNEL
       • S1#SHOW INTERFACES ETHERCHANNEL
