CAnt ping from my switch to connected router

I am not sure why, but I can not ping from inside my switch to the connected router.

Switch:

interface FastEthernet0/48
switchport trunk encapsulation dot1q
switchport mode trunk
!
interface GigabitEthernet0/1
!
interface GigabitEthernet0/2
!
interface VLAN1
no ip address
ip helper-address 192.168.1.150
no ip directed-broadcast
no ip route-cache
shutdown
!
interface VLAN100
description Voice_Vlan_Bldg1
ip address 192.168.1.251 255.255.255.0
ip helper-address 192.168.1.150
no ip directed-broadcast
no ip route-cache

interface Ethernet0/0
ip address 192.168.1.252 255.255.255.0
no ip directed-broadcast

A straight thru cable connects f0/48 on switch to e0/0 on router.

Can you show us the config for your router?

mmicha

You need to setup the router side to do trunking as well, or remove the trunking from the switch side.

Take a look at:

Thas your problem. Trunking is setup on your switch, but not your router.

removed trunkport from switch, still nothing.

Glen Krinsky

Are you trying to ping the ip of E 0/0 on your router?

Glen Krinsky

How is port 48 configured now?

jbell72

ASKER

yes, and e0/0.1. Attempting from inside of my switch consoled in.

mmicha

I'd try setting a default gateway on your switch to point to the router and see what happens...

jbell72

ASKER

interface FastEthernet0/47

And nothing follows.....

mmicha

You probably also want to setup the management VLAN on the switch, along with the default gateway.

management vlan is vlan 100, nevermind the description.

I removed gw command and it still works. SO what worked was putting port 48 in access vlan 100? I know it works right now, but is that right? It should be a trunk port. My goal is to get vlan 10 working on the router to use as a voice vlan and gw of 10.0.1.1 since my switch is layer 2. I have a phone plugged into f0/1.

interface Ethernet0/0.1
encapsulation dot1Q 10
ip address 10.0.1.1 255.255.255.0
no ip directed-broadcast

So I can ping back and fourth from router to switch, I can even ping from 10.0.1.1 to the switch. However, my home dhcp server and call manager is 192.168.1.150. I can ping from erotuer to .150 but from interface 0/0.1 10.0.1.1 I can not ping the call manager...
