CISCO SWITCHES FOR SMALL and MEDIUM BUSINESS
Introducing the next generation of Cisco Small and Medium Business Switches. Cisco is refreshing its SMB Switch portfolio. Click here to learn more.
Hello,
Are there any specific settings for the SG200-26 when used with ESXi vSwitches (in a load-balancing configuration)
For example 2 hosts, 4 NICs per host, each NIC transferring traffic from 2-3 VLAN's (trunk ports)
I am able to setup the VLANs on the switches and test connectivity on the individual ESXi vmnic adaptors, but when I use two adaptors in my vSwitch, I lose connectivity.
I dont see anything relevant in the logs.
Any recommendations? How are you guys setting up your SG200's to work with ESXi?
Thank you
Alex
Solved! Go to Solution.
I'd recommend you make a static LAG. The information from what you posted in pretty spot on from that knowledge base.

Hi Alex, you should be able to set up a Link Aggregation (LAG) on the switch. The switch supports 802.3ad.
To set up a LAG, go to port management -> LAG management
You will need to remove all VLAN off the ports you want to bundle. However, once the LAG is built, you may add the vlans you want again.
Also consider, the trunk links are 802.1q. The switch does not support per-vlan-spanning tree (pvst). This means you may only have 1 spanning tree instance even for different vlans.

Thank you Tom, is this same as EtherChannel?
I am reading on this VMware KB article that I should either use static LAG or EtherChannel:
(Quote below)
Note: There are a number of requirements which need to be considered before implementing any form of link aggregation. For more/related information on these requirements, see ESX/ESXi host requirements for link aggregation (1001938).
The following explains link aggregation concepts:
The following are EtherChannel supported scenarios:
This 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
!
I'd recommend you make a static LAG. The information from what you posted in pretty spot on from that knowledge base.

Thanks so much Tom for the prompt responses - I will try this!
But I just realized the SG200-26's are not stackable, right? how do the two switches know they are part of the same LAG?
Ie
LAG1:
host1, nic1 -> switch1, port1
host2, nic1 -> switch2, port1
LAG2:
host1, nic2 -> switch1, port2
host2, nic2 -> switch2, port2
LAG3:
host1, nic3 -> switch1, port3
host2, nic3 -> switch2, port3
LAG4:
host1, nic4 -> switch1, port4
host2, nic4 -> switch2, port4
This way I would have
LAG1: 2G - VM network
LAG2: 2G - NFS Storage front-end
LAG3: 2G - NFS Storage back-up
LAG4: 2G - ESXi features network (vMotion/FT)
I'm just realizing that I probably can not do this, unless I have the stackable SG500 series, right?
