Cisco 6500 VSS , VSL Link Connection Issue

Hello Everyone

actually i have two Cisco 6509E with two VS-S720-10G and want to run VSS on them

i do all the config same as cisco recommend, but i get somethings wrong on them, 1st. on switch2 , under "switch virtual domain" when i enter switch2, its not accepot and 2nd. non of 10G link goes up & so VSL link always down

here is my config and show commands

SWITCH#1
==================================
switch virtual domain 10
 switch mode virtual
 switch 1 priority 110
 mac-address use-virtual
 
redundancy
 main-cpu
  auto-sync running-config
 mode sso

interface Port-channel1
 no switchport
 no ip address
 switch virtual link 1
 mls qos trust cos
 no mls qos channel-consistency
 
interface TenGigabitEthernet1/5/4
 no switchport
 no ip address
 mls qos trust cos
 no cdp enable
 channel-group 1 mode on
!
interface TenGigabitEthernet1/5/5
 no switchport
 no ip address
 mls qos trust cos
 no cdp enable
 channel-group 1 mode on
 

======

SWITCH#2

switch virtual domain 10
 switch mode virtual
 switch 1 priority 110

redundancy
 main-cpu
  auto-sync running-config
 mode sso

interface Port-channel2
 no switchport
 no ip address
 switch virtual link 2
 mls qos trust cos
 no mls qos channel-consistency

interface TenGigabitEthernet2/5/4
 no switchport
 no ip address

 no cdp enable
 channel-group 2 mode on
!
interface TenGigabitEthernet2/5/5

Thank you all in advance

Hi,

What version of IOS are you running?

Can you post the output of "sh ver" from both switches?

as you see i use "adventerprisek9-mz.151-1.SY1" but now downgrade it to "s72033-adventerprisek9_wan-mz.122-33.SXJ2" , so nothing change and EtherChannel still not up

below are the show commands:

Ok, does the second switch have the same exact IOS?

under Portchannel  1 and 2 can you issue "shut" and than " no shut" and test again?

HTH

both of them have the same IOS, but in little difference that i think not Important SWITCH1 use sup-boot-disk and SWITCH2 user Disk0.

i also try shut and no shut at any time, and nothing happened yet

i think about something dummy and change the Fiber Optic Patch Cord ;)

 

at end there only one thing i should share with you: do i need to do anything for enabling 10G interfaces on SUP, as you know they ate jsut use for VSS , so it not possible to use them 

 

Ok the first thing we need to know is if the physical interfaces are up and running.

If they are not than you need to fix that first before moving on and configuring VSL link.

So, what is the output of "sh ip int brief te1/5/4, 5 2/5/4 and 5?

if these links are down, then you have physical layer problems and need to troubleshot the fiber cable and optics.

BTW, you don't need to enable the interfaces for 10gig.  For these interfaces 10gig is default.
