I have a customer that has two vlans setup on their idf switches (vlan 10, 20).
on the core switch they all come in on multiple fiber trunks set for vlans (1, 10, 20)
ports 1/0/1-8 are access ports on vlan 10
ports 2/0/1-8 are acess ports on vlan 20
now they want to be able to have cross traffic from ports 1-8 vlan 10 to talk to devices on vlan 20, and ports 1-8 vlan 20 to talk to devices on vlan 10.
can someone explain to me how to do this. (I'm pretty new at this but it makes no sense to me since it would be easier to get rid of the vlans since in doing this they seem to have no purpose).
i was told to setup vlan int on both vlans with ip addresses to use as gateways and the IP routing would take care of the rest, but I can't seem to make that work.
help, the more I go into this the more confusing it is getting.
Thanks for any help.
Assuming your core switch is L3 capable then depending on the model you may need to enable routing ie.
vlan 10 = 192.168.3.0/24
vlan 20 = 192.168.4.0/24
int vlan 10
ip address 192.168.3.1 255.255.255.0
int vlan 20
ip address 192.168.4.1 255.255.255.0
clients in vlan 10 have a default gateway of 192.168.3.1 and clients in vlan 20 a gateway of 192.168.4.1.
just to clarify;
my core switch has trunk ports. all trunk ports have vlan 1,10,20 on them.
also on my core switch I have ports gi1/0/1-8 as access ports on vlan 10
int vlan 10 ip address is 192.168.151.254.255.255.254.0
also on my core switch i have ports gi2/0/1-8 as access ports on vlan 20
int vlan 20 ip address is 192.168.152.254 255.255.254.0
ip routing has been enabled.
i set up access ports;
gi3/0/1 access port on vlan 10
gi3/0/2 access port on vlan 20
my laptop is setup for testing as;
i can ping the gateway for vlan 20 (152.254) and one of my ip cameras on the same vlan (152.100)
i cannot ping the gateway for vlan 10 (151.254) or any of my cams on vlan 10.
what am I missing?
thanks again for your input.
Thanks for posting the config. Based on this I would expect that devices in vlan 10 and vlan 20 should be able to communicate and am surprised that they do not. Can you tell us which switch port your computer is connected to and post the output of these commands
