Dear Guys,

Last day i had issue while doing the vss on new 4507E+R switch with 2 Sup engines.After connecting eachother both cables was not up and neighbour switch not showing in cdp as well.then we put the command like hw-module uplink select tengigaethernet then the links became to up .Then we started to configure VSS

VSS:

switch virtual domain 50
switch 1
switch 1 priority 110
mac-address use-virtual

switch virtual domain 50
switch 2
switch 2 priority 90
mac-address use-virtua

sw01:
int po21
switchport
switch virtual link 1
no shut

sw02:
int po22
switchport
switch virtual link 2
no shut

sw01:
int range ten 1/2/7-8
channel-group 21 mode on
no shu

sw02:

int range ten 1/2/7-8
channel-group 22 mode on
no shut

sh ether summ

Sw01:
switch convert mode virtual

Sw02:
switch convert mode virtual

Then we put RELOAD in both switch primary supervisor.After rebooting VSS is not formed and secondary switch is keep rebooting and its showing error like"Its SYNC confg since it is not in SSO mode"

Please help me that how to recover from the autobooting and to make it the both switches vss functionality.

Console into switch 2 and reboot the chassis. Post the entire boot-up process. We want to see what the switch is doing.
