trunking

[squaredeal]

I set up a trunk between 2 3560 switches,

I can see them as neighbors but cannot ping them

the config is

switchport trunk encap dot1
switchport mode trunk

this is on both switches

what am I doing wrong

jack

 

[robertjo24]

Are both switches set up with management IP's on the same subnet?
Same default gateways?

 

[squaredeal]

one is under a vlan300 on the 13 network and the other is it native vlan1 but on the 8 network

thanks for the reply

Are the trunk ports connected with a crossover cable? Also, post a sh vlan and sh vtp server

Burt

 

[burtsbees]

Also, do you have ip routing enabled?

Burt

 

[squaredeal]

I will post both config files shortly.

Jack

 

[vipergg]

On the first switch put an ip address on vlan 1 and make sure the second switches default gateway is pointed to that address . The way it is now it can never ping.

 

[squaredeal]

This is the switch i need to connect to on fa0/11

I cant get a copy of the other switch right now but i did enter the ip routing command , I am using a crossover cable and the vtp mode is set to transparent.
as well as the trunking commands are

thanks guys

[vipergg]

Do a show vlan and make sure all your layer 2 vlan definitions show active under this command . If you need more help post a "show vlan" and a sh int trunk command here .

[vipergg]

You don't have the same native vlan on each side of the link , these have to match in order for the trunk to work. Looks like the native is 1 on one side and 300 on the other , this won't work. either make the native vlan 1 on both sides of the trunk or make it vlan 300 on both sides. Also i am not sure why on one side it only shows 400 as active . all your vlans should show active like they do on your 2nd switch.
The other question is which switch is doing the routing ?

switch 1
vtp domain cisco
ip routing


int vlan 1
interface Vlan1
ip address 172.17.8.1 255.255.255.0

interface Vlan300
ip address 172.17.13.254 255.255.255.0

interface FastEthernet0/22
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk native vlan 1

-------------------------------------------------------------

switch 2
vtp domain cisco
no ip routing

interface Vlan1
ip address 172.17.8.23 255.255.255.0

ip default-gateway 172.17.8.1

int f0/1
switchport encapsulation dot1q
switchport mode trunk
switchpor trunk native vlan 1

 

[squaredeal]

the ip routing--this should only be on one side of the trunk?
to add voice vlan the command would be for example
switchport voice vlan 301?


ok ..so this is what i will have on both sides,

interface FastEthernet0/48
