I can ping both workstation and VOIP Phone, when connected individually to the port.

I can ping VOIP Phone when workstation is connected to it.

I can not ping workstation when connected through VOIP Phone.

 

 

Can any one let me know why I  can not ping workstation when connected through VOIP Phone?

Can the workstation ping its default GW?

 

Has the workstation received a DHCP address when connected through the phone?

 

WHy "hybrid VLAN"?

 

WHat is the port config of each port each of those 3 devices is connected to?

Its fixed now, I had to actually run the DHCP for VOIP. ;p

Well Hybrid allows multiple vlans on an edge port

Workstation (VLAN 100) :

interface Ethernet1/0/1
 poe enable
 lldp compliance admin-status cdp txrx
 port link-type hybrid
 port hybrid vlan 200 tagged
 port hybrid vlan 10 100 untagged
 undo port hybrid vlan 1
 port hybrid pvid vlan 100
 undo voice vlan mode auto
 voice vlan lldp

 

Workstation / VOIP Phone on port :

 

interface Ethernet1/0/2
 poe enable
 lldp compliance admin-status cdp txrx
 port link-type hybrid
 port hybrid vlan 200 tagged
 port hybrid vlan 10 100 untagged
 undo port hybrid vlan 1
 port hybrid pvid vlan 100
 undo voice vlan mode auto
 voice vlan enable
 voice vlan lldp

 

DHCP with two scopes for both VLANS:

 

interface Ethernet1/0/8
 poe enable
 lldp compliance admin-status cdp txrx
 port link-type hybrid
 port hybrid vlan 10 100 200 untagged
 undo port hybrid vlan 1

Trunk allows multiple VLANs on an edge port.
