i have just started at my new employer 's HQ, where i came to find a flat network with a subnet of 192.168.10.0/24 which was diminishing in IP addressing space. so what i did was to implement a router on a stick setup with one router, five cisco 2960 catalysts, one per floor and five subnets, one per switch per floor. 192.168.10-14.0/24

the users in all five VLAN's are able to access all network resources, email, internet, business system etc. the problem i have is, i cannot ping any host in any VLAN when on any catalyst.

but when i am on a host on VLAN 10 (192.168.10.0/24), i am able to ping all the hosts in the same VLAN as well as in all the other four VLAN's. but when on a a host on VLAN 11 (192.168.11.0/24), i can ping all hosts in the same VLAN but cannot ping all hosts in VLAN 10 of which i am able to ping when on a host in VLAN 10.

i hope my scenario is comprehensive

please assist?
 
thanks a whole lot guys, its working now, i shut vlan 1 and change the default gateway to 192.168.14.1

"The default-gateway points to the router for the management network" this is what i had not known, and it was the solution, thanks cluebird

just one more thing guys, i can ping all hosts in all other vlans when on this catalyst (vlan2) but when on a host in this vlan 2, there is one machine i cant ping, 192.168.10.14 but i can ping it when on a host in the native vlan 192.168.10.0

not even rdp works.
 
Check the default gateway on the host 192.168.10.14 that you can't ping when on a different subnet.

If you can ping it locally but can't ping it from another subnet it may not have a gateway configured.
