I have 3 3560's on a fibre ring terminated on a gbic blade in a 6509.
The two gbic ports on the 6509 are configured 'set trunk n/n on dot1q'.
The gbic ports on the 3560's are 'switchport mode trunk'. I can ping all 3 3560's from the 6509 but I can only ping one of them from my P.C. The 3560 I can ping from my p>c is the one not connected to the 6509. VTP details are correct, all three 3560's can see all vlans. Any ideas?
Are you using a routing protocol on the 3560
like ospf or eigrp? No
You will need to add static routes to them pointing back to the 6509 address
ip route 0.0.0.0 0.0.0.0 192.168.2.2
ip route 0.0.0.0 0.0.0.0 192.168.2.1
