configuring trunk betwen IOS (12.2) and CATOS (8.5(2))

[Rosa Ladeira]

switch 1: WS-C2960S-24PS-L / c2960s-universalk9-mz.122-55.SE7 / port g 1/0/28

switch 2: WS-C6509 + WS-X6K-SUP1A-2GE / cat6000-supk9.8-4-5.bin / sc0

configuring trunk on fiber interfaces

switch 1#sh interfaces g 1/0/28 trunk

Port        Vlans in spanning tree forwarding state and not pruned

Gi1/0/28    1-7,10-11,14,20-21,23,105-107,110,112,114,130-131,160,168,177,232,254,931
switch 1#

on switch 2 the possibilities are:

switch 2> (enable) set trunk 5/1 [on | off | auto | desirable | nonegotiate] [dot1q | isl | negotiate]

What should I choose?

Thanks Rosa

 To match encapsulation type on both switches try "set trunk 5/1 dot1q" on the second switch.

Hi!

I have executed on switch 2:

swtich 2 >  (enable)  set trunk 5/1 on 1,2,3,4,5,6,7,10,11,14,20,21,
23,105,106,107,110,112,114,130,131,160,168,177,232,254,931 dot1q

I have gotten:
