I have the following scenario:

EX2200 Switch whit

• ge-0/0/6 set as an access port on VLAN 80
• ge-0/0/0 set as a trunk port connected to a catalyst switch and various vlans allowed to pass includin vlan 80

On the Catalyst Switch.

• port #3 set up as a trunk port that receives traffic from the EX switch.
• port 46 is set up also as a trunk port that connects to a cisco router. Port #48 is where the host used to be connected

host -> EX2200 -> Catalyst -> Router

the problem is that this EX2200 is a new addition to the network and the host connected previosly to the catalyst switch.

traffic is not getting from the host to the router, but the router can send ARP request to the host.

following is the relevant configuration:

Catalyst Switch:

interface GigabitEthernet1/46
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 80,82,83,93,289
 switchport mode trunk
 mtu 1532
 media-type rj45
 speed 1000
 duplex full
 arp timeout 300
!

interface GigabitEthernet1/48
 switchport access vlan 80
 switchport mode access
 mtu 1532
 media-type rj45
 speed 100
 duplex full
 arp timeout 300
 no cdp enable
!

EX2200 Switch:
