SG300-10 Unable to ping from vlans

[jornelas74]

Having issues with machine pinging from VLAN. I can ping each VLAN from CLI on the switch. I can ping the VLAN IP from the workstation. When I try to ping outside it fails.

- from switch do: ping <vlan_XYZ--interface_ip_address> source <vlan_10-interface_ip_address> count 10

If it goes everytime you have already inter vlan IP switching.

- What vlan is your workstation located at ?

from switch do:

show arp (look for your WS hw address and IP and vlan)

then do:

ping <WS-interface_ip_address> source <vlan_XX-interface_ip_address> count 10

if it doesn't go then you have a problem in the return of packets from WS to switch

- What are you trying to ping? all vlan ip addresses from WS-host machine at vlan 20? are you specifying the correct interface in the host?

- What is the IP configuration of the workstation? Dynamic(from where?)/Static DNS/no-DNS, netstat -rn, arp -a

- What's between your workstation and the switch? if you have a router you'll need to add a manual route to your vlan in the router

- How many paths are there to your workstation? disable spanning tree to see effects.

I would like to gather more information to help diagnose this issue. What outside IP address are you trying to ping from the host? Also, what IP address is configured on the host? What type of device is the host directly connected to? Are you using a layer 2 or layer 3 switch?
