i have a number of switches on the network; most of them being 3550. the problem is with a 24 port 3550. i have a 3550 12g with gi0/1 assigned to vlan102 (172.17.102.0) with .1 as the address on the 12g. on the 24 port i have the same vlan102 with .2 being the specified address. default vlan on both switches is vlan1 but the 24 port has nothing specified for vlan 1 because no working ports belong to it. the networking is working perfect. the only problem i have is that when i open the cluster management interface, the 24 port is shown in red and says 'no ip address'. gi0/2 is connected to the 12g via fiber link.
heres the config on the 24 port:
!
version 12.1
no service pad
service timestamps debug uptime
service timestamps log uptime
service password-encryption
!
hostname IND-SB-LAB
!
enable secret 5 ...

ip subnet-zero

Hi,
Check/update the following :
1. What is the management vlan on both the switches. That should be the same. as per your config, it seems that vlan 102 is management vlan on both the switches.
2. have u connected your switches via trunk or access link.
3. also upload the config of 12g switch.
regards

the native vlan on both switches is vlan1. is that what you are referring to as management?
from what i have read, trunk is for multiple vlans across the link which we are not doing. i put the 'switchport mode access' on the gi0/2 port of the 24 port, so i think to answer your question i am using access link.
here is the config for the 12g:
!
version 12.1
no service pad
service timestamps debug uptime
service timestamps log uptime
service password-encryption
!
hostname IND-SB-12G
!
enable secret 5 ...
!
ip subnet-zero
