Guys,
In IEWB Lab-20, the task it to do LACP port-channel b/n SW1 and SW3, where
SW4 is in the middle.
SW1==(19,21)==============(13,15)==SW4==(19,21)==============(19,21)==SW3
*Task:*
Configure interfaces 19 & 21 on SW1 and SW3 as ISL Trunks.
These links should be bound togather by LACP negotiation.
Do not use DTP to accomplish this.
SW1 and SW3 are in VTP domain 789. SW4 is in domain 10.
*Problem:*
I could get following config working for dot1q encapsulation, but *not for
ISL*. Can someone plz try on their rack ?
*SW4:*
interface GigabitEthernet1/0/13
switchport access vlan 100
switchport trunk encapsulation dot1q
switchport mode dot1q-tunnel
switchport nonegotiate
l2protocol-tunnel point-to-point lacp
!
interface GigabitEthernet1/0/15
switchport access vlan 200
switchport trunk encapsulation dot1q
switchport mode dot1q-tunnel
switchport nonegotiate
l2protocol-tunnel point-to-point lacp
!
interface GigabitEthernet1/0/19
switchport access vlan 100
switchport trunk encapsulation dot1q
switchport mode dot1q-tunnel
switchport nonegotiate
l2protocol-tunnel point-to-point lacp
!
interface GigabitEthernet1/0/21
switchport access vlan 200
switchport trunk encapsulation dot1q
switchport mode dot1q-tunnel
switchport nonegotiate
l2protocol-tunnel point-to-point lacp
!
*SW1 and SW3:*
interface GigabitEthernet1/0/19
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
channel-group 1 mode active
!
interface GigabitEthernet1/0/21
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
channel-group 1 mode active
!
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
TIA,
Naveen.
