Unable to ping between two switches in GNS3

Hello Cisco Experts,

I've configured two switches (really they are two routers with NM-16ESW modules in them) in GNS3.  The switches connect to each other on fa1/12 (on both ends).  I have configured vlan 990 on both switches.  Below is the show vlan id 990 results of each switch:

SW1
SW1#show vlan-switch id 990

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
990  POINT-TO-POINT_CONNECTION_TO_SW2 active    Fa1/12

VLAN Type  SAID       MTU   Parent RingNo BridgeNo Stp  BrdgMode Trans1 Trans2
---- ----- ---------- ----- ------ ------ -------- ---- -------- ------ ------
990  enet  100990     1500  -      -      -        -    -        0      0

SW2:
SW2#show vlan-switch id 990

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
990  POINT-TO-POINT_CONNECTION_TO_SW1 active    Fa1/12

VLAN Type  SAID       MTU   Parent RingNo BridgeNo Stp  BrdgMode Trans1 Trans2
---- ----- ---------- ----- ------ ------ -------- ---- -------- ------ ------
990  enet  100990     1500  -      -      -        -    -        0      0

The vlan information above looks good to me.

Below is the results of a show ip interface brief run on each switch:

Vlan1                      unassigned      YES NVRAM  up                    down
Vlan990                    10.147.255.250  YES NVRAM  up                    up

Looking at the SVI for vlan 990, everything looks good to me.

Finally, below is the configs for both fa1/12 and the interface vlan 990 on each switch:

SW1:

interface FastEthernet1/12
 description CONNECTS TO SW2
 switchport access vlan 990


interface Vlan990
 description POINT-TO-POINT_CONNECTION_TO_SW2
 ip address 10.147.255.149 255.255.255.248

SW2:

interface FastEthernet1/12
 description CONNECTS TO SW1
 switchport access vlan 990

interface Vlan990
 ip address 10.147.255.250 255.255.255.248

If this was a real environment and not GNS3, I would be looking at maybe a bad cable.  All the configs look good to me.  Does anyone see anything I'm missing?

Thanks,
Nick

You are missing "switchport mode access" in your config on FA1/12
ndalmolin_13Author Commented:
I added the switchport mode access on both fa1/12 interfaces, but that did not make a difference.
JustInCaseCommented:
Your ip addresses are not in the same subnet.
SW1
ip address 10.147.255.149 255.255.255.248
SW2
ip address 10.147.255.250 255.255.255.248

Actually, it is.  251 is the broadcast address
Daniel SheppardSenior Network Analyst - Core & PerimeterCommented:
Never mind...  Just noticed it is 149 not 250.  Sorry, it is 1 am here...

Haha
