Trunking vlans to 877

[Shouou]

I followed the example in the previous thread thread557-1525711
But i just can't get trunk working with vlans from a HP Switch to my 877 Router.

interface FastEthernet0
 switchport trunk allowed vlan 1,2,1001-1005
 switchport mode trunk

interface FastEthernet1

interface FastEthernet2

interface FastEthernet3

interface Vlan1
 description Primary
 ip address 192.168.160.1 255.255.255.192

interface Vlan2
 description Secondary
 ip address 192.168.160.65 255.255.255.192

ip default-gateway 192.168.160.1

vlan 1
   name "Primary"
   untagged 1-48
   ip address 192.168.160.2 255.255.255.192
   tagged 49-52
   exit
vlan 2
   name "Secondary"
   tagged 1-52
   exit

I already have a work around of using 1 ethernet port for each vlan and then use 2 cables to the network switch, but where I want to install this router there is only enough patching for 1 link cable not 2.

Is there anything different I have to do for the 877 as we never have a problem with combining vlans with Cisco Switches with HP’s?

Pulled this out of my 877 & HP switch:

Cisco 877:

Hmm,

Is is a stange one, i'm already trunking the vLANs like your example but it still does not work.

 

[Shouou]

Ah Sorted it. Don't Trunk (tag) vLAN 1 on the HP switch but leave Cisco as is.

i was using Port 50 as my link from switch back to the 877 Router

[Code HP Switch]
ip default-gateway 192.168.160.1

vlan 1
name "Primary"
untagged 1-52
ip address 192.168.160.2 255.255.255.192
exit
vlan 2
name "Secondary"
tagged 1-52
exit
[/code]

I tested it with an IP phone on vLAN 2. It works.
Finally i dont have to use a different cable for each vlan going to the cisco router.

Cisco Vlan1 is always "untagged"

...unless you configure a different native VLAN on the trunk port...

 

[DennyHeack]

unless indeed
