Depending on which AOS switches and brand of SFP's being used, you may need to try a few different settings to get the SFP to come up when used with the new ASE switches.
For a 1531 connect to a 1560 the following worked perfectly.
1531 Switch
!
interface gigabit-switchport 0/12
speed 1000 nonegotiate
no shutdown
!
1560 switch
!
interface 10GigabitEthernet 1/2
spanning-tree edge
speed 1000
!
For a 1544F this config seems to work
1544F Switch
!
interface gigabit-switchport 0/12
speed 1000
no shutdown
!
1560 switch (set to auto)
!
interface 10GigabitEthernet 1/2
spanning-tree edge
!
For a 1550 this config seems to work
ASE Switch 1560:
!
interface 10GigabitEthernet 1/2
switchport mode trunk
speed 1000
description downlink to 1550 xgig 0/4
!
AOS switch 1550
!
interface xgigabit-switchport 0/4
description Link to 1560 1/2
no shutdown
switchport mode trunk
speed 1000 nonegotiate
!
As I come across more combinations I will update.
