Hello!
We bought a few 2540 switches (JL357A) and like to connect them to our Cisco 9300 Switches via direct attach cables. The switches are running on the latest firmware (YC.16.09.0001) and I enabled support for unsupported transceivers. The DACs we use are Cisco SFP-H10GB-CU3M.
Looking at Table 1 in the "Allow unsupported transceivers"-guide from aruba, "10-GbE SFP+ 3m Direct Attach Cable" should be supported.
But when looking at the output of
show tech transceivers
it shows otherwise:
Transceiver Technical Information:
Port # | Type | Prod # | Serial # | Part #
-------+-----------+------------+------------------+----------
52 *| ?? | ?? | unsupported |
* third-party transceiver
and the LED for the port is flashing orange.
As far as i understand, when enabling unsupported devices, any DAC should work.
Any hints on how to resolve this issue?
I don't want to change to aruba DACs and play the same game on the side of the Cisco Switches again.
