Could you please advise. we have set a new network using 4507 as cores,3750 as distribution,2960 as access switches. now the vlans doesn't see each other and you can't access remotely to any host on a different vlan! how can i assign the IT ports the privilege to see all VLANS and access them. i only can access servers remotely if i disabled the firewall.
P.S: the IT are connected to the access which is connected to the distribution which is connected to the cores. the distribution and access are clients and the cores are servers
