2650 vlan routing porlbem

hi all,
i have enabled Routing on the switch and each vlan can be communicated, but i am unable to get out onto the internet with this configuration:

ip default-gateway 192.168.0.1 [router`ip]
ip routing
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
untagged 1-42,45-50
ip address 192.168.0.254 255.255.255.0
no untagged 43
tagged 44
exit
vlan 2
name "VLAN2"
untagged 43
tagged 44
ip address 192.168.1.1 255.255.255.0
exit
ip route 0.0.0.0 0.0.0.0 192.168.0.1
password manager
password operator

i also config a static route at the router:
192.168.0.0 255.255.0.0 192.168.0.254

now,192.168.1.x can ping 192.168.0.x execpt 192.168.0.1

any ideas?may be an hardware problem?
Thanks in advance.

Re: 2650 vlan routing porlbem

Hi,

try to ping the router from the switch. Is this working? If not check VLAN membership of the router port ("show vlan port xx" -> should be VLAN 1) and arp resolution (show arp). Most likely there is no layer 2 connectivity between the switch and the router.

Cheers,

Re: 2650 vlan routing porlbem

Hi,

please run the following commands on the router:

ping 192.168.0.254
ping 192.168.1.1

Then check the ARP table and the Routing table on the router (please paste it here if feasable). This will give you a clue whats going on.

Re: 2650 vlan routing porlbem

On the 2650 switch go to VLAN 2 and "untagged 41". This statically put port 41 to VLAN 2. From you intial configuration notice that port 41 is still on the default VLAN. You have to assign it to VLAN 2
