Handy commands...
I've got Juniper ones and a non-Juniper one here:
Xcvr 51 REV 01 740-038623 QSFP+-40G-CU1M
Xcvr 52 REV 01 740-038623 QSFP+-40G-CU1M
Xcvr 53 NON-JNPR UNKNOWN
And I'm seeing some interesting stuff. On the Juniper cable:
TFXPC0(vty)# show qsfp 1 identifier
Identifier: QSFP+
Connector type: No Separable Connector
Encoding: Unspecified
Vendor name: Molex Inc.
Vendor OUI: 00093A
Vendor PN: 1110409055
Vendor Rev: B
...redacted...
Transceiver code:
10G/40G Ethernet: 40GBase-CR4
On the Non working one:
FXPC0(vty)# show qsfp 3 iden
Identifier: QSFP
Connector type: Copper Pigtail
Encoding: Unspecified
Vendor name: Molex Inc.
Vendor OUI: 00093A
Vendor PN: 112-00178
Vendor Rev: A0
...redacted...
Transceiver code:
Gigabit Ethernet: 1000Base-CX
So maybe this cable is only 1000Base? What makes this even more weird is that
the 4300 sees it as the same, but it comes up as 40Gb:
(vty)# show qsfp 1 identifier
Identifier: QSFP
Connector type: Copper Pigtail
Encoding: Unspecified
Vendor name: Molex Inc.
Vendor OUI: 00093A
Vendor PN: 112-00178
Vendor Rev: A0
...redacted...
Transceiver code:
Gigabit Ethernet: 1000Base-CX
root@4300-STACK> show virtual-chassis vc-port
fpc0:
--------------------------------------------------------------------------
Interface Type Trunk Status Speed Neighbor
or ID (mbps) ID Interface
PIC / Port
1/1 Configured -1 Up 40000 1 vcp-255/1/0
I would expect this to come up at 1Gb if that was the case. The QFX5100s also
refuse to bring up those DACs even if they are the only cables available.
