If you are wanting an external device to communicate with an internal port then the external port must be on the same Port Aggregator group as the internal port  As far as I understand there are no switchport mode access command options.  The Simple mode does not allow traffic to pass between port aggregator groups.  If it is not working the way you think it should respond you may have to turn off simple mode and configure the switch manually.  Hope this helps,
Hi All, I try setup M6348 blade switch with simple mode as below, but I could not setup external port connect with end device (host), will it support? Example: Port Aggregator group 1 - Internal port 1 with switchport vlan access 888 (untag) Port Aggregator group 1 - external port 33-36 connect to Cisco switch port 3 and 4 with switchport vlan access 888 (untag) I try connect end device (host) to M6348 external port 36 but M6348 internal port 1 (VM) could not ping end device If end device connect to Cisco switch port e.g. port 8, M6348 internal port 1 (VM) ping successful. I try connect end device (host) to M6348 external port with Port Aggregator group 2, it could not allow add vlan 888, will M6348 with simple switch mode support above setup? Many thanks. Best regards, Chung
