ISL is a deprecated technology no longer formally supported on a variety
of Cisco platforms.  Now would like be a good time for you to look
towards the ratified alternative of dot1q, assuming the rest of your
infrastructure can/will support it.

| So I wonder if it is really possible to build an ISL-bundle like
| 1750+1924-EN or 1750+2924XL-EN, to build an ISL-trunk between 1750 and a
| catalyst and to make 1750 route IP between VLAN subinterfaces.
| If anyone was a success to do so -- please, let me know. Thank you.
