I've run into a strange issue bringing up a new vg350 (essentially a 3945E with high-density FXS modules). The topology is the VG350 with 2 SFP uplinks to a 6509 VSS. While troubleshooting, I've disabled 1 of the 2 uplinks, but that 1 shows up/up on both sides. Both sides can see the other via CDP neighbors. Both have a route for the other, but I can't ping across.
I have 3 other production VG350's running the same code (15.4(3)M6), same upstream 6509, same subnet...only difference is that they're using GigE vs the SFP's.
I have a TAC case open, but it's progressing very slowly. Just checking to see if anyone's run into a similar issue before or if anyone has any ideas.
The config is super simple (and exactly the same as working configs except for the BVI mac and ip address and media-type sfp):
bridge irb
interface GigabitEthernet0/1
no ip address
media-type sfp
bridge-group 57
interface GigabitEthernet0/2
no ip address
shutdown
media-type sfp
bridge-group 57
interface BVI57
mac-address bbbb.bbbb.bb01
ip address 10.50.51.5 255.255.255.0
bridge 57 priority 65535
bridge 57 protocol ieee
bridge 57 route ip
ip route 0.0.0.0 0.0.0.0 10.50.51.1
