GLBP issues with a new SVI

ALIAOF_

Level 6

I have two 4948E's configured with GLBP and and they have been working fine.  I configured another SVI with GLBP config and when I do "show glbp vlan 120" I see that both switches are Active and the group member only shows the local switch.  Any ideas will be appreciated:

Switch 1:

interface Vlan120

description "Development Network"

ip address 10.1.120.2 255.255.255.0

glbp 120 ip 10.1.120.1

glbp 120 priority 110

glbp 120 preempt

glbp 120 weighting 5

glbp 120 load-balancing weighted

glbp 120 authentication md5 key-string 7 xxxxxxxxxxxxxxxxx

glbp 120 weighting track 120 decrement 20

An update for some reason I can not ping the IP address of the SVI's from the switches.  I have the following on the two switches:

Switch 1:

spanning-tree vlan 1,5,9,48,200,250 priority 24576

Switch 2:

spanning-tree vlan 1,5,9,48,200,250 priority 28672

Would this be an issue I need to add VLAN 120 to this as well?

Well figured it out yes that was the issue.  New VLAN needs to also go into that statement. 

spanning-tree vlan 120 priority 24576 (Primary)

spannig-tree vlan 120 priority 28672 (Secondary)

I just ran those two commands on the switches primary and secondary and all is working now.  Note:  that command appended to the existing did not overwrite it.
