Catalyst 3560 optimize for iSCSi traffic

[imanco671]

Hello Community,

I would like to properly configure my L3 to support iSCSi traffic.

My L3 acts as an internal router between 4 different subnets.

I have a iSCSi SAN on my network. A Windows server has Microsoft iSCSi initiators connecting to the SAN.

Thanks Community!

As it's is not like fcoe in terms of being lossless however you might try to put all traffic coming from the iscsi port to be set with cos 5 and put it in the priority queue and enabled in the inbound direction

Assuming in you vm you have certain ports/Vlan dedicated for this type of traffic not mixed with other vm traffic

Hope this help

Well I found that the iSCSi traffic was the cause of my issues. My backup server was on a different subnet than my SAN, once I switched my backup server to the SAN subnet, all is fine.

I will have to implement your suggestions to make the iSCSi traffic priority.
