Workstation can't ping ESXI Load Balance cluster through LACP port-channel

[douglas.mckee]

Hello,

We have our IIS 10.0 hosted on our ESXI server and are able to ping from the ESXI server to the distribution switch and can also ping the IIS servers as well. Anything that's on the same subnet can ping the network load balancing cluster. Please see attached.

***ISSUE***
Cannot ping the network load balancing cluster from the User workstation

Note:
VMWARE KB states to put a static ARP entry into the router/switch mac address table

Hello,

did you try the static ARP ?

Router(config)#arp 172.16.1.31 20cf.303a.f7c9 arpa

George,

Thanks for the quick response.

We tried the Router(config)#arp 172.16.1.31 20cf.303a.f7c9 command but when we do a "sh mac address-table address" afterward the mac address doesn't show up in the table.

We also tried "mac address-table static 342d.4562.b532 vlan 140 interface Gig1/0/1" and states you can't add a layer 2 mac address to a layer 3 interface. Understandable, since we have an IP address under this interface.

Do you have any other workarounds that may work? Another article mentioned the daughter card on the router processing layer 2/3 and somehow linking the arp requests to the daughter card.

Thank you,

Doug

Doug,

Does it work when you don't use Etherchannel at all? Just trunk ports from the ESXi hosts to the switch.

Also, how about an Etherchannel with mode "on" (not lacp)?

HTH,

The switch with the port-channel is a 9396PX and is part of our data center. There's currently about 30 other applications that traverse this port-channel constantly and would need to test this after hours. Our server personnel stated that they don't want to use a trunk for the IIS application.

I found the command listed below on the 9396PX and was wondering if this would be a possible solution or if it could cause issues with our current applications.

ip arp allow-static-arp-outside-subnet

Thank you,

Doug
