Hey guys,
in the last weeks I got two strange problems with 10GB ports on different 2960-X switches.
Problem 1:
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 52 WS-C2960X-48TD-L 15.2(3)E1 C2960X-UNIVERSALK9-M
I connected the two 10G Ports with a QSFP-4SFP10G cable. When I plug in the twinax both tranceivers were detected correctly. On the other side I had a Mellanox SX1012 and configured a LACP channel. On the Catalyst only Port 2 had a link and nothing on Port 1. So I switched the cables/twinax gbics and after that again only Port 2 was up. So this has to be fixed on the Catalyst side. After some testing I just rebooted the switch and Port 1 had a link???
Problem 2:
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 52 WS-C2960X-48TD-L 15.2(2)E C2960X-UNIVERSALK9-M
Port 2 has a SFP-10G-SR GBIC inserted and is an uplink to a cheap Netgear 10G switch (don't blame me, customer insisted). After 2 months the systems on the Netgear were gone! I checked the link and GBIC, everything was fine. There were hitcounts on "sh int te1/0/2", GBIC detected and port type connected. The customer replaced the Netgear with a new one, same thing, bought a D-Link 10G switch, same thing.
Reboot on Catalyst and with all switches the uplink runs properly???
I checked the resolved caveats for all following images, nothing found regarding 10G.
Anyone observed similiar issues?
Thanks!
Michael
