VLAN Assistance

Greetings All,

I need some VLAN assistance please. I would like to be able to make some ports on switch 3 members of the DO_Admin VLAN which resides on switch 2. Switch 1 physically resides between switches 2 and 3. Is it simply a matter of adding the DO_Admin VLAN to switches 1 and 3, or is there a better way? Please give configuration examples. All three switches are layer 3, switch 3 does support OSPF. Any assistance would be greatly appreciated!


Switch 1 (5308)

vlan 8
name "DHS_To_DSE"
untagged A3
ip address 10.37.28.1 255.255.255.0

Re: VLAN Assistance

hi john
you can create on each switch Do_Amin vlan
assign untag port on switches for Do_Admin vlan member port
after all uplik port(between switches)you make tagged port Do_Admin vlan

cenk

Switch 1 (5308)

vlan 8
name "DHS_To_DSE"

Re: VLAN Assistance

Thank you for your help.

However,

I'm still unable to connect. Does an IP need to be assigned to the VLAN on each switch?

1-can you create each switch vlan 41
Yes- I have created the vlan on each switch

2-can you assing tree switch between uplink port vlan 41 tagged port

I'm sorry, I'm not sure what your asking. I have tagged the interfaces that connect the three switches.

3-can you create untag port on each switch

Yes- aminimum of one untagged port for VLAN 41 exists on each switch

4-when connect pc vlan 41 all pc (anyone switch)default must be gateway address 10.37.64.1

Yes - the PC I attempted to connect with has the gateway set at 10.37.64.1
