Hi,exports:
I have a question about load-balance between trunk.
Sw1============Sw2
sw1 and sw2 are connected using fa0/1 and fa0/2.
There are 2 vlans on both switches.they are vlan 1 and vlan2.
I want to load-balance between the trunk link.Only allowed traffics of vlan
1 pass through fa0/1,
and traffics of vlan 2 pass through fa0/2.
These are 3 options below.
option 1:
interface fa0/1
switchport trunk encapsulation isl
switchport mode trunk
switchport trunk allowed vlan 1
channel-group 10 mode on
interface fa0/2
switchport trunk encapsulation isl
switchport mode trunk
switchport trunk allowed vlan 2
channle-group 10 mode on
interface port-channel 10
switchport trunkencapsulation isl
switchport mode trunk
option 2:
interface fa0/1
switchport trunk encapsulation isl
switchport mode trunk
spanning-tree vlan 1 port-priority 64
interface fa0/2
switchport trunk encapsulation isl
switchport mode trunk
spanning-tree vlan 2 port-priority 64
option 3:
interface fa0/1
switchport trunk encapsulation isl
switchport mode trunk
switchport trunk allowed vlan 1
interface fa0/2
switchport trunk encapsulation isl
switchport mode trunk
switchport trunk allowed vlan 2
I know option 1 and 2 are OK.
My question is that,which is better ? option 1 or option 2 ?
If option 3 works? and why?
Any inputs will be appreciated.
regards.
David.
