2) PAGP ( Port Aggregation Protokol ) ( Faqat Cisco qurilmasida ishlaydi)
*Staticheskiy agregirovaniya (Masofadan boshqarib bo’lmaydi,lekin ishlashi tez,ushlanishlar bo’lmaydi,Cisco tafsiya etadi buni)
Ulangan ikkala tomondagi portlarga quyidagilar talab etiladi:
-Bir xil tezlikdagi port bo’lishi k.k
-duplex rejimda bo’lishi k.k
- native vlan
-ruxsat etilgan Vlan diapazoni
-trunking status
active Enable LACP unconditionally
auto Enable PAgP only if a PAgP device is detected
desirable Enable PAgP unconditionally
on Enable Etherchannel only
passive Enable LACP only if a LACP device is detected+
Staticheskiy nastroyka qilamiz
Nastroykani switchlarni bir biriga ulamasdan oldin qilamiz
1-switch:
Switch>enable
Switch#configure terminal
Switch(config)#int range fa0/1-4 // 1-portdan to 4-portgacha olamiz
Switch(config-if-range)#channel-group 1 mode on //bularni hammasi 1 ta gruppa qildik
//bir nechta fizicheskiy interfeyslarni bitta lagicheskiyga aylantirdik
Switch(config-if-range)#exit Switch(config)#exit // 2 rejimga o’tamiz
Switch#wr mem // nastroykani saxranit qilamiz
2-switch: 2-switchni ham xuddi shunday nastroyka qilamiz !
Tezlik 4 ta port ulaganimiz uchun 400 mb/s bo’ladi.
Dinamicheskiy Nastroyka qilamiz
Switch 1:
Switch>en
Switch#conf ter
Switch(config)#int range fa0/1-2 //2-switch uchun nastroyka qilamiz
Switch(config-if-range)#channel-protocol lacp //lacp pratakolini yoqamiz
Switch(config-if-range)#channel-group 1 mode active //asosiy switchni active qilamiz unga ulangan //switchni esa passiv qilish tavsiya etiladi
Switch(config-if-range)#exit
Switch(config)#int range fa0/3-4
Switch(config-if-range)#channel-protocol lacp
Switch(config-if-range)#channel-group 2 mode active
Switch(config-if-range)#exit
Switch(config)#exit
Switch#wr mem
Switch 2:
Switch>en
Switch#configure t
Switch(config)#int range fa0/1-2
Switch(config-if-range)#channel-protocol lacp
Switch(config-if-range)#channel-group 1 mode passive
Switch(config-if-range)#exit
Switch(config)#exit
Switch#wr mem
Switch 3:
