I have two brand-new Catalyst 4500X switches running cat4500e-UNIVERSALK9-M. The switch has GLC-T 10Gbs copper SFPs in it. All the ports are set to "switchport"
I am trying to crate a VSS pair, but I cannot bundle interfaces T2/7 & 8. I am getting error:
Te2/8 is not compatible with Po10 and will be suspended (trunk mode of Te2/8 is dynamic, Po10 is trunk)
I followed the procedure as follows
Switch1:
switch virtual domain 5
switch 1
switch 1 priority 110
switch 2 priority 100
interface port-channel 10
switchport
switch virtual link 1
no shut
interface range ten 2/7 & 8
channel-group 10 mode on
Switch 2:
switch virtual domain 5
switch 2
switch 1 priority 110
switch 2 priority 100
interface port-channel 20
switchport
switch virtual link 2
no shut
interface range ten 2/7 - 8
channel-group 20 mode on

If I look at the config on switch 1, it looks correct
interface TenGigabitEthernet2/7
switchport mode trunk
switchport nonegotiate
no lldp transmit
no lldp receive
no cdp enable
channel-group 10 mode on
service-policy output VSL-Queuing-Policy
!
interface TenGigabitEthernet2/8
switchport mode trunk
switchport nonegotiate
no lldp transmit
no lldp receive
no cdp enable
channel-group 10 mode on
service-policy output VSL-Queuing-Policy
But po10 is down (waiting to aggregate)
Is there something I am missing here? What am I doing wrong?
