IBM Datapower XI52 will transmit only to 5K switch but works on 7k

[leebarton2003]

Hi

We have multiple IBM Datapower XI52 boxes, with fiber conenctions.

We can get transmit only, no receive talking to a 5k Switch, but if i move the same transceiver and cable to a 7k switch it works fine, and we can connect, transmit, receive, and ping.

is this a known issue?

XI52 : Firmware 5.0.0.8

Cisco 5k switch

BIOS : 1.5.0

System: version 5.1(3)N2(1b)

Image file : bootflash:///n5000-uk9-kickstart.5.1.3.N2.1b.bin

Cisco 7k switch

BIOS : 3.22.0

System : version 6.1(3)

Image file : bootflash:///n7000-s1-kickstart.6.1.3.bin

Thanks
Lee

It could be a transceiver compatibility issue. What transceiver model are you using at the switch end?

We use identical transceiver make and model at both ends (cisco) , and we move the transceiver from the 5k switch to the 7k switch and it works there too.

Transceiver compatibility with the NX-OS, not with the distant end. Different transceiver types are compatible with different OS levels.

The transceivers on both ends are

Cisco : SFP-10G-SR

Hmm. Those are pretty standard transceivers and should work fine.

Can you confirm the port operating correctly on the 5k - perhaps by connecting it on a new VLAN to the 7k? That would isolate the problem domain.
