[c-nsp] How to get VLAN from Switch to a Router via another switch

[Michael K. Smith - Adhost]

Hello:

It looks like you've set up a trunk port facing your PC.  That won't work
unless you have a VLAN-aware NIC.  On the port facing the PC, try:

Switchport mode access
Switchport access vlan 900

You probably want to "default interface fa0/2" from a global config prompt
to clear the trunking info out first.

Hey everyone!

I'm trying to get a couple of ports on a 3550 to appear on a router.
normally easy, but I have another switch in between.

Hardware: 7206, 2 * 3550

Machine (1.1.1.2/30)
	|
	| Cat 3550-A - port 3 - dot1q 900
	|
	| Cat 3550-A - port 2 trunk port to 3550-B)
	|
	| Cat 3550-B (port 4 trunk port from 3550A)
	|
	?????
	|
	| Cat 3550-B - port gig0/11 Trunk to 7206
	|
    7206 VXR - GigE .900 with (1.1.1.1/30)

Question is. how do I get dot1q trunk from 3550-A onto the 7206vxr?

How to connect the two trunk ports.. I'm not sure.

Config:

3550-A

interface FastEthernet0/2
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,900
 switchport mode trunk
!
interface FastEthernet0/3
 switchport access vlan 900
 switchport mode dynamic desirable

PC plugged into port 3 with 1.1.12/30


3550-B

interface FastEthernet0/4
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,900,901
 switchport mode trunk
.
interface GigabitEthernet0/1
 description Trunk to 7204VXR-G1/0
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,12,301-310,900,901
 switchport mode trunk


7206vxr

interface GigabitEthernet1/0.900
 description Test Trunk
 encapsulation dot1Q 900
 ip address 1.1.1.1 255.255.255.252
!


Thanks!
