Connecting Verizon Metro ethernet and (2) 3750's

Here is my issue. This is my first metro ethernet connection.


Site A (1) Cisco 3750X connected to ethernet to media fiber converter.  IP 10.0.8.1  vlan 8

Site B (1) Cisco 3750X connected to ethernet to media fiber converter.  IP 10.0.8.2  vlan 8

Site A will come up

Site B line will come up, protocol is down

Originally the metro E was connect to two juniper firewall and it worked. Got rid of one firewall and wanted the routing to be on the Cisco switches instead of the junipers. Site A is currently connected to the cisco and Site B to a Juniper Firewall as I cant get it to come up on the switch.

Site A

interface Vlan8

ip address 10.0.8.1 255.255.255.0

interface GigabitEthernet1/0/7

description UPLINK_TO_METRO_ETHERNET

switchport access vlan 8

power inline never

spanning-tree portfast disable

Gi1/0/7   UPLINK_TO_METRO_ET connected    8          a-half  a-100 10/100/1000BaseTX

Site B

interface Vlan8

ip address 10.0.8.2 255.255.255.0

interface GigabitEthernet1/0/3

description UPLINK_TO_METRO_ETHERNET

switchport access vlan 8

power inline never

spanning-tree portfast disable

I have tried this as a trunked interface also with the same result. Also when i go 100/full the line goes down but on the juniper it works.
Any input is welcome.

Hello,

Is the SVI on site B up/down? is g1/0/3 on a 3750 stack? what's its status? Please provide:

sho int vlan 8

sho int g1/0/3

sho vlan id 8
