I am inheriting this network and need help with packet losses experienced by users on network.
I have 2 powerconnect 6248s (stacked for redundancy) with iSCSI connected to five 5424 powerconnects as Access switches (for users and servers).
Currently there is only VLAN1 on the network, other than the 3 created on the iSCSI.
i don't see any trunks on the connecting ports connecting the switches together; so i am going to have to trunk these ports.
My concern is, is it ok to create a couple VLANs on the 5424s and trunk them to the 6248s which have 3 VLANs created on them for the iSCSI.
I haven't seen VLANs created in this way before and was wondering if it will work. InterVLAN and default routing will be provided by a Microsoft ISA server connected to the 6248s.
All these switches are acting as layer 2 switches. 6248 acting somewhat as a core switch.
Any ideas will be greatly appreciated. Thanks
