I have workstation on VLAN 100 (Access Switch). When doing a source ping from another vlan (15) on the core (6509) i can ping some of the workstation on vlan 100, but can not ping others.
If i source ping a workstation from VLAN 100 i get replies with no problems. The access switch is directly connected to the core. The gateway for the workstations on vlan 100 is the ip address configured on the access switch (4506-VLAN100). Any recommendations
