Re: Support


I am assuming that you have all the vlans configured in 3 switches and trunks are working properly.

Config for 3550:

Config t

Int vlan 2

ip address a.a.a.1 x.x.x.0

no shut

Int vlan 3

ip address b.b.b.1 x.x.x.0

no shut

Int vlan 4

ip address c.c.c.1 x.x.x.0

no shut

Int vlan 5

ip address d.d.d.1 x.x.x.0

no shut

Configuration of the 3550 trunk port connected to 2950(1)

Int gig x/y

switchport trunk encapsulation dot1q

switchport mode trunk

Configuration of both the 2950 switch ports

Int gig x/y

switchport mode trunk

After the config is done, Make sure that your PC's connected to the respective vlan has the gateway defined as the 3550 SVI IP addresses.

Let me know if you have any questions.

HTH,Please rate if it does.
