This article focuses on concepts, limitations, and sample configuration of Link aggregation / NIC Teaming / LACP / Ether-Channel connectivity between ESX 3.x Server and a Physical Network Switch, in particular, Cisco and HP.
The following is a Cisco EtherChannel sample configuration:
interface Port-channel1
switchport
switchport access vlan 100
switchport mode access
no ip address
!
interface GigabitEthernet1/1
switchport
switchport access vlan 100
switchport mode access
no ip address
channel-group 1 mode on
!
ESX Server and Cisco switch sample topology and configuration:
Run the following command to verify EtherChannel loadbalancing mode configuration:
Switch# show etherchannel load-balance
EtherChannel Load-Balancing Configuration:
src-dst-ip
mpls label-ip
EtherChannel Load-Balancing Addresses Used Per-Protocol:
Non-IP: Source XOR Destination MAC address
IPv4: Source XOR Destination IP address
IPv6: Source XOR Destination IP address
MPLS: Label or IP
Switch#show etherchannel summary
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator
M - not in use, minimum links not met
u - unsuitable for bundling
w - waiting to be aggregated
Number of channel-groups in use: 2
Number of aggregators: 2
