4500X not pingable post VSS

[rajitoor55]

I am configuring new 4500x switches. After i did vss configuration, i am not able to ping to/from the switch. Below is how it is connected to one of the core switches right now. I have tried configuring SVI or assigning IP directly on the interface, nothing seems to work.

Core-Switch#
Vlan17                 172.17.0.1      YES NVRAM  up                    up 

interface TenGigabitEthernet1/1/5
 switchport
 switchport mode trunk
 switchport trunk allowed vlan 17

TenGigabitEthernet1/1/5 is up, line protocol is up

4500#
Vlan17                 172.17.0.20      YES NVRAM  up                    up 

interface TenGigabitEthernet2/1/32
 switchport
 switchport mode trunk
 switchport trunk allowed vlan 17

TenGigabitEthernet2/1/32 is up, line protocol is up

ip route 0.0.0.0 0.0.0.0 172.17.0.1

I have tried this as well. Management interface as well does not work

interface TenGigabitEthernet2/1/32
ip address 172.17.0.10 255.255.0.0

Can you post the output of "sh run" and "sh redundancy" from the vss switch?

Below is redundancy output and attached running config

[Reza Sharifi]

Configuration register = 0x2101

Can you change the config register to 0x2102, save config, reload both chassis and test again?

Issue was VSS domain number which same to that of the connected switch. Changing VSS domain number resolved issue.
