Cisco SG300-10 pinging problem

jschreck

Good afternoon,
I am currently building a layer 3 switch. It has been almost 4 years since I touched a Cisco switch/router, so any help would greatly be appreciated. The following is my current running config.

GWPCoreSW1#show running-config
config-file-header
GWPCoreSW1
v1.4.0.88 / R800_NIK_1_4_194_194
CLI v1.0
set system mode router

My problem is vlan 20, pcs on port ge3 and ge 4 are not able to ping vlan 21 ge 5 and 6.

I was able to ping from 10.20.0.1 to 10.20.0.2, 10.20.2.1 to 10.20.0.2, 10.20.2.1 to 10.20.2.2. How ever anything leaving from vlan 20, 10.20.0.1, going to 21, 10.20.2.X gets dropped. There are no other switches in the chain, this switch and pcs directly connected are labbed at this time. I need to get this switch up for November. Any Ideas and thank you!

the running config shows "set system mode router". Have you saved your configuration and rebooted since issuing that command?

jschreck

Yes I have sir. Just to double check I did again.

clarson

what does the routing table look like? does show ip route run on that switch?
And, are you sure you want your ports to be trunks?
usually, hosts are just access ports.
